Robert Writes In: 

I’m having some issues with the thermostat which goes back to the “wake up screen” or other error messages. If I unplug the stove it seems to solve it. Just wondering if this is a common issue and whether there is an updated model or something else going on with the stove?

Mr. Pellethead Replies: 

The issue here is likely as simple as the thermostat wire connections.  Three wire system, Red and Green are for power and White is for communication between the wall control and main board.  Dashes in the upper left screen would indicate problems with the white wire connections.  Cycling the wakeup screen is a loose connection of the red or green or both wires.  The interruption could be the crimped connectors at the stove terminal block or the connections inside the wall control.  Could also be a pinch of the t-stat wire between the wall control and the stove.

    My Quadrafire Mt Vernon AE stove has been great for the past ten years even though I’ve had to replace everything from the baffle and firepot to the auger assembly. My problems have been in finding listed Quadrafire parts by the part number. The ash drawer catches were worn out and none were to be found except at a local hardware store. Now, I can’t find a dealer who can assure me that the door rope gasket, p.n. SRV7034-177 is correct for my stove. Can I always trust the manufacturer’s part number?

    • Earth Sense Energy System says:

      Thanks for contacting us, happy to assist.

      Although manufacturers change part numbers over the years, the earlier part number will always supersede. An Authorized dealer has access to the manufacturers database to look up any part number for any part or accessory ever used or sold. It surprises me that the dealer you mentioned couldn’t assure you of the part number for that gasket or ash drawer catches.

      Moving forward you can feel free to contact us regarding any needs or questions you may have. We are the largest dealer in the country of pellet stoves and of Quadra-Fire pellet stoves. Although we don’t have every Quadra-Fire part on our website yet, we are continually adding and we do stock virtually every single part for the Mt Vernon AE.

      Got a problem with my Mt VernonE2. Red light 4 x flash code. Feed motor doesn’t turn. Just try feed motor, vacuum switch from another stove and still nothing. Everything is clean…Don’t know what’s going on! Any tips or ideas?

      Thanks

      • pellethead_admin says:

        Thanks for contacting us Fred, happy to assist. The 4 Blink Red Light Code/flashes Indicates ‘Missed Ignition’. Here are some things to look at.

        1. Fuel Hopper Empty – Make sure the hopper has fuel
        2. Feed Motor Does Not Turn – Inspect Feed Motor Circuit (Hopper Lid Must Be Closed, Vacuum Switch Must Be Closed, Snap Disc Must Be Closed, and Feed Motor Must Be Plugged in). Ensure there are no jams in the feed tube.
        3. Dirty Appliance – Clean Unit Including the Firepot, Exhaust Path and Venting System
        4. Igniter has no power or is defective – Check Igniter Lead Connections. You can also check the igniter with an Ohm meter to ensure it’s in proper range – https://youtu.be/z4wmCc96rVI
        5. Exhaust Probe Not Properly Installed – Secure exhaust probe to exhaust blower housing – Keeping its wire away from hot surfaces.
        6. Ignitor Chamber Plugged with Debris – Clean Ignitor Chamber Area.

        Let us know what you find here Fred, happy to assist however we can.

        Thanks,
        Mr. Pellethead

        • Fran says:

          My thermostat keeps going panel keeps going blank, flickering, and or shutting completely off where the screen will look like there’s no power to it. Sometimes the stove will turn on full blast and I’ll have to pull the plug cuz I can’t control the heat… please help

          • pellethead_admin says:

            Good afternoon Fran, apologies on the delay. Let’s start with the basics first and check the wiring on the Wall Panel Thermostat and the connection points of those wires to the unit. If everything looks in line with that more than likely we have an issue with the wall control thermostat or circuit board in the unit. Feel free to call us as well at 800-236-6647 and ask for our technical service dept.

            Thanks,

  • Dustin heaton says:

    Ive lost fuel selections on my thermostat

    • Earth Sense Energy System says:

      Dustin,

      Thanks for contacting us. I would first tell you to check all the wires and connections. Then do a hard reset by unplugging the stove and waiting 30 seconds before plugging back in. From there if your thermostat is still not functioning and showing all the aspects and selections, you more than likely will need a new Wall Control.

      Here is a link to the Wall Control – https://pellethead.com/product/quadrafire-mt-vernon-ae-edge-60-wall-control-thermostat/

      Any other questions please let us know.

      Thanks,

    • Mike says:

      When you plug in my Mt Vernon stove the exhaust fan turns on then the screen says auto clean and then nothing happens. I disconnected the arm that slide the pot and that moves freely. So the stove stays in auto clean and nothing happens. I have replaced the control board.

      • pellethead_admin says:

        Hey Mike, happy to help. Let’s check the wall thermostat wiring first – possible communication issue. Check the white wire going from the stove to the wall unit and check for breaks or kinks in the wire.

        Keep us posted.

        Thanks,

        • Mike says:

          Yeah just checked the wires there was a spot that looked kinked. Cut it out hooked everything back up and still the same problem. I just replaced the auto clean assembly today too.

          • pellethead_admin says:

            Thanks Mike. I just forwarded all of our correspondence to our lead MTV AE techs. Will follow-up with you here ASAP.

            Thanks,

          • pellethead_admin says:

            Hey Mike,

            Just heard from our lead MTV AE tech – Is the fire box door closed and the switch contact made and no “door open” icon displayed on the wall control? If the burn pot bottom moves freely without the arm attached then the auto clean motor / switch assembly will need to be removed and tested. Once removed thoroughly inspect the wire harness for damage. Then check the assembly for binding, remove the motor from the assembly and try cycling the auto clean again to see if the motor turns. If not, considering a new board and the wall control displays “auto clean”, the motor needs to be considered for replacement.

            Keep us posted.

  • Jeff Stutzke says:

    Had my Mt. Vernon about 6 years now…having the problem that it just shuts down un-expectantly…starts fine but when goes into Med, burn mode….boom…just shuts down. Tried all sorts of low hanging fruit replacement parts but now think its the control board…thoughts? Just a general comment…Pellet stoves are great when they work…until they don’t. They take lots of maintenance and even then, keep your fingers crossed that none of those moving parts goes out…ha. Can’t beat the good old fashioned wood stove….

    • pellethead_admin says:

      I can agree to an extent but just as with any other complex appliance there is maintenance that needs to be done. This holds true with wood stoves as well if you want the units to last. The issue that you describe sounds as though it might be a thermocouple error but there are further questions that I would have to narrow it down to the root problem. Feel free to reach out to our tech support department at (920)779-6647 ext:3721 and our tech support guy Greg is more than happy to help solve this issue.

  • Andre says:

    My Mt. Vernon AE is not giving any error codes at the moment, but is not igniting. It cycles through the start up for a long period of time then does a cleaning, dumping all of the unused pellet into the ash pan.

    • pellethead_admin says:

      Thanks for contacting us, happy to help. I would suggest that we check the ohms on the igniter first so we can determine right off the bat if it’s an issue with the element or not. Here is a video on testing the igniter element https://youtu.be/z4wmCc96rVI. For your Mt Vernon AE, if you have the original 380 watt igniter ohm range should be 35.5 – 43.5. If you have the pellet only 300 watt igniter ohm range should be 43.5 – 53.5.

      Let us know if the igniter is in proper range or not and we can assist further from there.

      Thanks!

      • A Barnett says:

        Do you sell the wiring harness?

        • pellethead_admin says:

          Thanks for the message. Yes, we offer all of the various wire harnesses for the Mt Vernon AE and other Quadra-Fire models. Do you know which wiring harness you need? Common Harnesses would be:
          1. AC Power Out
          2. DC Power Out
          3. Auger/Auto Clean
          4. Door/Hopper
          5. Overtemp Snap Disc
          6. Igniter

          There are several different ones for the AE model. If you have a part number that would be great, if not let us know exactly what is happening and we can help decipher with you.

          Thanks,

  • Mike says:

    When you plug in my Mt Vernon AE the exhaust blower turns on and then the screen says auto clean but nothing is happening. I replaced the control board, and just replaced the auto clean assembly. What should I try next?!

    • pellethead_admin says:

      Mike,

      While I am waiting to hear from our techs, let’s double check the auto clean porkchop/burnpot bottom to make sure it’s not jammed or binding on anything.

      • Mike says:

        Before I changed the auto clean assembly I disconnected the arm going to the burn pot and slid it back and forth just fine. And I just ordered a new one from you guys on Amazon yesterday and a new thermostat.

        • pellethead_admin says:

          Thanks Mike, Tech also messaged one more thing this morning to check – Check that the over heat snap switch is not tripped. Located on the drop tube above the wing nut holding the drop tube thermocouple. This snap switch is a manual reset and if tripped then begs the question, WHY?

          • Mike says:

            Checked the snap switch looks fine. Didn’t look tripped.

          • pellethead_admin says:

            Hey Mike,

            Followup notes here from the technicians.

            The snap switch is still a possibility until it’s tested or bypassed to rule it out.

            New auto clean motor assembly, but, does it work if removed and the AC power cycled to engage the auto clean? Still not determined.

            The vac switch / auto clean switch wire harness isn’t out of the question.

            Getting closer to the control board but I’ll call HHT if it gets to that.

            Those are the latest notes Mike. We can schedule a call as well if that is helpful. Keep us posted.

      • Mike says:

        The firebox door is closed and there is no door open icon on the display. The pork chop moves freely when not attached. And it’s a brand new motor and assembly that I purchased from you guys.

        • pellethead_admin says:

          Thanks Mike. Checking in with the team, will circle back shortly here.

          • Mike says:

            I will try those things this weekend. And let you know. Thank you guys so much for helping with this. 2 of my local quadrafire dealers didn’t want anything to do with helping.

          • pellethead_admin says:

            Sounds good Mike! It’s our pleasure, we are happy to help and I am certain we will get this figured out and get you back up and running properly again.

            Keep us posted.

            Appreciated

        • pellethead_admin says:

          Mike,

          Tech Just spoke with HHT on this. Notes:

          Called HHT and they are saying that the likely issue given all that has been replaced is how the board is interpreting the auto clean “home” switch. In the home position, or slide plate / burn pot fully closed, the board recognizes this start point for the next time the auto clean cycles. Without the acknowledgment of the start point (switch closed) the auto clean cycle is thrown into chaos and won’t move. Keep in mind that the over temp snap switch on the drop tube still has to be verified with an ohm meter that it is closed. Recommended next steps;

          1. Ohm the hi limit to confirm closed.

          2. Ohm the auto clean switch in the home position to ensure it is closed.

          If these check out as closed then proceed as follows;

          1. Apply new female spade connections to auto clean switch wires, try the auto clean.

          2. Still not working? Replace the female spade connection to the high limit wires, try the auto clean.

          3. Still not working? Order a new vac switch/auto clean wire harness as the problem could be the harness molex.

          Keep us posted Mike.

          • Mike says:

            Ok so I replaced the thermo couple that is attached to the burn pot and IT WORKS!!!! Thanks again for all your help!!!

          • pellethead_admin says:

            Mike, that’s great to hear!! I will share this with our tech team as well. Very pleased to hear you are warm once again. Any future questions just give us a shout.

            Thanks!

          • pellethead_admin says:

            Hey Mike, Just a quick final note from our lead tech on this: Very plausible and something I did consider. Only a laptop would have spotted it clearly. Under this scenario the thermocouple, basically an ESP thermistor in this case, would have malfunctioned as a high temp reading causing a safety override of the auto clean. I personally have never seen that happen!

            Again, so glad we got this figured out. Appreciated!
