I have a 2008 mt. Vernon that I can not get the error code “convection blower over i” to clear. I tried 2 new convection blowers with no luck. Any advice? I am thinking it’s the control board but it’s not very old.
Hey Bryan,
Running this past our lead technicians. That’s an odd error code. As soon as I hear back I’ll follow-up ASAP.
Thanks,
Hey Bryan, here are some notes from our lead tech on this issue and error code.
This error code means that there is an issue with current flow in the room fan circuit. 4 causes, 1)wire harness and connector molexes, 2)room fan connection terminal corrosion, 3)motherboard connection terminal corrosion, 4)motherboard. #1 is the least expensive and usual culprit. Rule out #2, new fan.
Hope that is helpful, if you have any further questions just let us know. Thanks!
This is Chris. I have similar error message, but it says Combustion Blower Over I. I’ve cleaned all contacts. The fane runs for period and then right before it hit high speed it gives me that error.
Thanks Chris. Touching base with our techs on this. I will follow-up ASAP.
Had problem with calibration setting, just keep adjusting.
Replaced thermostat some issue. What is the problem?
Hey Jack,
Feel free to email us direct with additional information on the issue and we’ll do our best to assist. [email protected].
Appreciated,
I’m experiencing the same issue ever sense replacing the control board. Stove runs fine on medium setting but throws code everytime trying high. I’ve replaced convection blower, blower harness, drop tube thermocouple, and snap disk. I’m completely lost at this point.
Thanks for the message Keith. What error code is reading on the wall control when you run the unit on high?
Convection blower over i
Thanks Keith.
Let me run this past our most experienced MTV AE Tech and follow back up with you. We’ll do our best to get you back up and running 100% again. Given the time here on Friday, it may not be until Monday that I hear back, but we’ll message back asap. Appreciated.
Hey Keith, Heard back from our lead technician this morning and wanted to follow-up. In discussion with HHT, it’s a mystery error put in the logic by engineers that has no documented trail as to what it all means other than “the current to the room fan is sensed to be too high”. I have always followed the diagnostic for error “room fan jammed”, which looks like it’s already been done. There is one more item that needs to be checked and that would be the DC voltage output from the power supply to the motherboard. It will be the white and red two wire harness that links to the motherboard by all the aluminum heat sinks. Check the voltage at the molex that plugs into the board, with the stove plugged in the DC voltage will be between 14.9 DCv and 15.2 DCv.
It varies between 14.9 and 15.3
Is that small variable likely to b the problem?
Running this past the tech here Keith. I will follow back up ASAP. Appreciated.
Hey Keith, Quick Note Here from the tech, will follow up tomorrow with you. The voltage output does vary slightly from one power supply to another and any particular output should be steady. I will verify that tomorrow.
Thanks,
Hi There Keith, I wanted to touch base with you here. Our lead tech that was assisting has been unavailable currently. Personally I do not think a variable that small is the problem here as there can be slight variables simply based on the power supply. If you would like, I can try to reach out to Quadra-Fire on your behalf, otherwise here is the email and contact info direct – https://forgenflame.com/pages/contact-us. If I hear further information back from our technician, I will be in touch right away. Thanks much.
If you could reach out to Quadra fire that would be great. Don’t want to throw any more parts at it
Sounds good Keith. We’ll reach out to Quad on Monday and follow up ASAP. Appreciated.
Good Morning Keith. Our lead Mt. Vernon AE tech reached back out today and has spoken to the factory as well. ‘I tested two different power supplies this morning and both fluctuated in the range between 14.9 and 15.1 Vdc. It appears to be a normal occurrence when testing this voltage type and quantity and as long as it floating in the 15 Vdc range that’s what the manual calls for. It needs 15 volts so 3 different 12v components can run at the same time. Seems like everything other than the board has been replaced which leaves the control board. The control board can be sent in for testing, sending the room fan and wire harness would be beneficial as well’.
If you decide you want to send in your control board for testing (and possibly your blower and harness) please let us know. I can get let you know the cost for this service and get a work order in our system for the lead tech on this. Given the nature of the part, we would also want to insure it for shipping. If there is a local Quadra-Fire dealer near you, you can see if they offer technical diagnosis testing services on something like this as well.
Keep us posted, happy to help however we can.
Appreciated.
The board was replaced with a board I purchased through this site. Issue began after that. Thanks for your help though. Can’t really take the stove apart, medium heat it is I guess.
Hey Keith, didn’t know you replaced the control board and that is when the issue started. In our system I show the control board was ordered/shipped 12/16/2022 – Does that sound correct to you? HHT offers a 1 year warranty on replacement parts/manufacturer defects, but we are beyond that point if the date I’m seeing is correct. Once you can take the stove apart, we will absolutely work with you on this, get that board tested and determine if therein lies the issue. Keep us posted, greatly appreciated.
Hey Keith, I was speaking with Matthew Johnson who manages the eBay platform to get him up to speed. He stated you did tell him about the control board in the initial messaging, I just didn’t see it here in our thread. If I understand correctly, you purchased the board 12/16/2022, but didn’t install it until the following year after something happened with the power supply – is that correct? Any specific details will be super helpful. Thanks.
Purchase date sounds right. Unfortunately as far as warranty goes I let it sit in a box for a year before I actually needed it. The control board that went bad melted where the A/C power comes into the board. I replaced the board and the a/c power wire. Then started having this issue. All other parts were replaced trying to fix this error.
Thanks for going through everything here Keith, good information. Reach back out to us here when you are able to pull out the control board – even if that is at the end of the season here. We’ll work with you on getting that sent in for diagnostics/testing so we have a clear path forward.
Appreciated.
What’s the fee for board diagnostics? Also are the board repairable?
Thanks for the message back Keith. Typical cost to perform control board diagnostics would be $75.00 + shipping expenses. Given your situation here we would cut that to $35 primarily to cover the shipping cost w/insurance back to you. We really just want to help figure this out and get you back up and running 100% again. We do not repair control boards unfortunately. If it is an issue with the board, we should be able to identify and pin-point where that is. There will be a diagnostic report. There are electrician folks out there that do perform control board repairs, however there are none that we work with. In the event that you need a new control board, we would work with you best as we can on costs.
Thanks Keith.
Did you ever get a response to a repair fix
I have a Mount Vernon AE pellet insert. On shut down, whether temp was reached or auto clean. I get a clicking noise that sounds like metal against metal every 5 sec and continues until the stove shuts down. This only happen when on the stove is shutting down. Any suggestions.
Hey Eric,
Ran this past our lead technician – His notes on this: It’s not a clicking sound made by a motor/blower but rather a ticking or popping sound from expansion and contraction of the metals. At this point the stove has been real hot and is now cooling. I had one or two I came across in the field that were very similar and both were inserts. If I recall correctly there is a real thin layer of sheet metal between the firebox and hopper and you can duplicate it in startup if you overload the firepot at ignition and build heat fast.
One of our other techs mentioned: Could it be happening when it is going through the auto clean? Auto clean rail noise or something from underneath the firebox floor?
Let’s see if we can pin-point the area where the noise is coming from – if you have a stethoscope, even a child’s play one, it can really help to pinpoint the area where the noise is coming from.
Keep us posted, happy to help.
My Mt. Vernon AE thermostat is blank, no illumination. Following the user manual and troubleshooting guide I verified AC power from power supply to control board and verified 15 volts DC at the control board. I verified 3.3 volts DC all the way to the thermostat pins on the back of the thermostat itself. According to the user manual under such conditions it is suggested to replace the thermostat, ordered replacement and its the exact same condition.
Which only goes to show, dont ignore troubleshooting 101. The red and green thermostat wires were reversed, feeling real dumb.
Thanks for the message Hal. Don’t feel dumb at all, this happens to all of us. Plus this is a great point for others as well – always check the simple things and basics first. Just glad to hear that you are back up and running again. Any future questions please let us know.
Appreciated!
My Mt Vernon AE says convection blower jammed. I’ve already replaced the convection blower fan, I’ve cleaned the unit inside and out, even the exhaust pipe outside the house. The new fan motor worked for 10 days and now getting same error message “convection blower jammed”. What do you suggest. Thank you
Thanks for contacting us Brent. I ran this past our lead technician. Here is the response back:
Four things likely causing this error code from best case to worst case scenario.
1. The number 3 (overtemp) snap switch located on the drop tube above the drop tube TC. Is the switch button tripped? Reset the switch button. Switch must be closed, check for continuity, could also be a spade connector issue showing up intermittently.
2. The wire harness connecting the room blower to the bottom and side terminals of the motherboard. Bad connection likely, replace if the #3 snap switch checks out ok. Check for burn marks at the blower molex connector. Any of the to the board and blower molex connections could be intermittently faulty.
3. Room blower is bad, replace.
4. Motherboard output to the room blower is bad, replace the motherboard.
If you want to check the power supply, the PS output for the motherboard DC plug-in should be 15 volts DC. I would be shocked if that was it since this has more to do with electrical path vs electrical output DC. Number 1 & 2 are most likely, #3 has been done and worked for a while which brings you back to #1 & # 2. The usual number one culprit is the wire harness for the room blower in my experience.
Keep us posted, happy to help.

Mijn Mount Vernon AE start gewoon op a.s de thermostaat dit vraagt. Cyclus ss- low en ss-med worden doorlopen . Kachel brandt prima. Echter opeens gaat de kachel in shutdown mode, de melding “Vacuüm Sw error” verschijnt in het display. Na de shutdown mode is de kachel in rust, en start na enkele minuten weer gewoon op, omdat de gewenste ruimtetemperatuur nog niet bereikt is.
Dient de Vacuüm switch in dit geval vervangen te worden ?
Thanks for contacting us. Having difficulty understanding your message, if you can resend in English we can try to assist.
I’m sorry
My Mount Vernon AE just starts when the thermostat asks it to. Cycle ss-low and ss-med are completed. The stove burns fine. However, suddenly the heater goes into shutdown mode, the message “Vacuum Sw error” appears in the display. After the shutdown mode, the heater is at rest and starts up again after a few minutes, because the desired room temperature has not yet been reached.
Does the Vacuum switch need to be replaced in this case?
Thanks for your message Rene. Before replacing the vacuum switch, let’s inspect the switch. Make sure the electrical wires are secure on the terminals for the switch. Let’s inspect the vacuum switch tube/hose. Make sure connection points are secure and check if there are any cracks or splits in the hose. From here it’s also good to check any areas of the stove where there may be an air loss or air blockage which would create this error. Let’s check your door and glass gasket to ensure it is sealing tightly all the way around. Let’s inspect the exhaust venting to ensure there is not blockage or heavy ash accumulation. If the fire looks good while it is operating, then most likely your venting and gaskets are good. If your fire seems lazy or sooty in anyway, we definitely want to check these areas. Keep us posted, happy to help.
Thank you. I wil check thuis. Btw, I tested the vacuum switch by unloosen the tube and very gently blow and suck. I hear the switch clicking. Does that mean the switch itself is functioning ok ?
Sorry for responding so late.
I disconnected the stove’s exhaust pipe from the chimney, and it was immediately clear:
it was almost completely blocked with ash , there was only a very small opening left. Cleaning the exhaust fan’s outlet and the connected T-piece solved the problem. After cleaning the fans and fan motors ( a lot of dust) everything runs really smooth, without the slightest sound, no noise at all. Thanks for your help and good advice.
René
That is wonderful to hear René! So glad we could be of assistance and that you are up and running smoothly again. Any future questions or needs please let us know.
Appreciated,
Hi, I have a Mount Vernon, and I have replaced the igniter, because it shows miss ignition, and continued to dump pellets in the ash pan, everything works correctly if the pellets are lite manually, just can’t get the stove to lite. Can’t determine the problem.
Thanks for contacting us, happy to help. Let’s get an ohm reading on the igniter element to ensure the replacement is in proper range. If you purchased the OEM 380 watt loop igniter, ohm range will be 35.5 – 43.5, if you purchased the OEM 300 watt loop igniter Ohm range will be 43.5 – 53.5. Additional Reference for testing https://pellethead.com/how-to-test-and-replace-a-stove-igniter-pellet-stove-ignition-troubleshooting/
If your igniter is in proper ohm range, let’s take a look at the igniter wire harness connections and check the fuse with a multi-meter. Reference of the Igniter Wire Harness – https://pellethead.com/product/quadrafire-mt-vernon-ae-edge-60-ignitor-wire-harness-oem/
Let’s start here, let us know what you find.
Thanks,
I’ve been getting the “Conv Blower Jammed” error for a while. It started when the blower motor was making a lot of noise. I assumed it was motor bearing so I replaced the blower (7000-260). Continued to get the error. I replaced the snap disc (230-1290) and the drop tube thermocouple (7000-381). I checked the harness and the plug to the control board has a center terminal that is darkened/burned. I checked continuity and it was fine. Not sure where to go from here.
Thanks for contacting us Glenn, happy to help. Running this past our lead Mt. Vernon AE technician. We will follow back up very shortly.
Appreciated,
Hi Glenn, thanks for your patience. Notes here from our technician.
The convection fan plugs into the motherboard at two locations, top and the left side. Is it a molex from the convection fan that has a burn spot or the board molex on the left side? Burnt or brown wires/plugs is never good on an AE.
If the wire harness is burnt start with that – https://pellethead.com/product/quadrafire-mt-vernon-ae-edge-60-convection-blower-distribution-fan-wiring-harness-oem/
The next would be the Motherboard if that doesn’t solve the fault – https://pellethead.com/product/quadrafire-mt-vernon-ae-edge-60-circuit-control-board-assembly-oem/
Any questions please let us know, happy to assist.
Thanks,
Greetings, I keep getting a Min. Fire Pot Temp error. I know this usually means that the stove has run out of pellets but that’s not the case. I Have cleaned everything and replaced the firepot thermocoupler. I emptied the hopper and made sure the auger was clean. Any input would be helpful.
Thanks.
Thanks for contacting us, happy to help. Yes, that error will indicate that the firepot temperature is under 500 degrees. Appreciate you sharing all of the things you’ve done so far. Before this error comes on does it seem like your stove is starting up correctly and feeding as it should in regular operation? Is your fire crisp and torchy or does it seem lazy in anyway? How is the flame height? Suggested to double check the positioning of the thermocouple and electrical connections. Make sure your firebox and ash door gaskets are sealing tightly all the way around. Keep us posted, happy to assist.
I have a Mount Vernon AE stove that blew an igniter. Fuse tested the igniter. Igniter was bad. I replaced the igniter. Igniter test good now the stove igniter glows when plugged in and will not shut off until unplugged.
Thanks for contacting us Jason. Sounds like the circuit board is giving constant power to the igniter element. Let’s get a good light and inspect the Igniter Wire Harness and the connection to the circuit board. See if there are any burn spots on the connection. See if anything is loose with the wire harness. Unplug and re-plug the wire harness to the circuit board. Keep us posted, happy to help. Igniter wire harness for reference – https://pellethead.com/product/quadrafire-mt-vernon-ae-edge-60-ignitor-wire-harness-oem/ | Circuit Board for reference – https://pellethead.com/product/quadrafire-mt-vernon-ae-edge-60-circuit-control-board-assembly-oem/
Thanks,
Hey Jason, one of our other techs just chimed in and recommended that you inspect the ‘AC Power Out’ wire harness as well and that connection to the board. Same thing, let’s look for burn spots or loose connection. Reference – https://pellethead.com/product/quadrafire-mt-vernon-ae-edge-60-wiring-harness-ac-power-out/
Thanks,
I have a mount Vernon AE stove and keep getting missed ignition code. I have replaced the igniter with an OEM one and have replaced the control board from your business through amazon. If you unplug the stove from the wall and plug back in, it will then heat the igniter and start and run perfectly fine. It will cycle fine for about 12 hrs and then throw the same code and not heat the igniter again until the unit is unplugged and restarted again, then it will work fine. Is there something i am missing in this system that could stop it from sending power to the igniter?
Thanks for contacting us Jeff. Spoke with our techs on this, and it could potentially be a failing high limit switch. As it ages, the internal contacts get high resistance or open slightly after hours of heating/cooling cycles. The control board sees this as an “overheat” and locks out the igniter. A full power cycle resets the logic and the switch temporarily closes again for another 8–16 hours. We can do a test bypassing the high limit switch. This is a safety switch, so we never want to leave it bypassed, just for testing purposes. Here is a video that will show you how to create a jumper wire to do this. https://youtu.be/FDVkbsHS95U?si=TYuFZOnNh938Sjwk It’s going to be snap disc #3, reference – https://pellethead.com/product/pellethead-replacement-quadrafire-heatilator-250f-high-limit-switch-w-manual-reset-snap-disc-3/
Keep us posted, happy to help.
Thanks,
I have a non ae mt vernon pellet stove i have to reset stove to get it to start it lights and runs for a half hour or so then the flame gets lazy as far as i can tell then shuts down prematurally be before themostat is satisfied, i should have started with i completly cleaned stove and pipe didnt help with issue, another symptom ive noticed since the stove has been acting up is that the convection blower cycles which makes sense with the lazy flame i also tried softwood pellets, normally run hardwood pellets didnt seen to run any different. any help you can give would be great the control board is less than 2 months old and replaced the thermocouple at same time. out of ideas
Thanks for contacting us. It sounds like your combustion blower is not operating at proper voltage based on what you are describing. The convection blower/room air fan does not have any effect on the fire, it is odd that it’s cycling – is it completely shutting on and off or is the voltage cycling with your room air fan?
Would suggest that you test the voltage with a multi-meter on each of these blowers during startup and in operation at the 4 different heat levels. We want to determine if it’s an issue with voltage coming to the motor or with the motor itself. We can also run each of these blowers to direct power to test how they operate at full line voltage. Video here on creating a test cord to do this – https://youtu.be/rlmiCYI2WPk?si=3C8oVF_3PUpRb6IZ
Keep us posted, happy to help and get you back up and running.
