Quadra-Fire Technical, Auger Feed Issues, 4 Spd & 3 Spd Control Boards

William Writes In-

Problem with the pellet feed on an Original Mt Vernon 4 speed, board Number 7000-126. Recently replaced the system control board. Getting blue flashing light at start and a green light. No red light in controller, red light on the back of stove. Black button on side of stove below speed control, to force feed more pellets sounds like it’s working. The Auger does not move or vibrate while clicking button. How would I know if it is the auger motor or the controller??

Mr. Pellethead Responds-

Happy to assist William. When power is applied to a cold stove you’ll see a momentary yellow light (thermocouple test), then for 60 seconds a blue flashing light (count equal to the board setting). If the stove is cold there should be no green or red light present. The green light only indicates an achieved thermocouple temperature reading of 200 degrees. The red light represents an achieved thermocouple temperature reading of 600 degrees. The green light indicates to the board proof of fire and signals the start of normal feed cycles.

Is the feed system totally not functioning?

The simplest issues would be a loose wire connection, feed system restriction, an auger jam, loose set screw on the auger motor shaft or vacuum line hose nipple blockage at the top of the auger tube.

The feed system circuit comprises of four components





The use of certain diagnostic tools such as a volt meter, ohm meter, jumper wire and 120 volt power cord would be used to isolate which of these could be an issue.

    hi need help I have a quadra fire free standing castile . will not feed pellets right from start. new control box ,thermocouple,and vacuum switch.bypassed snap disc 2,vacum switch still nothing.all cleaned out and sealed tight.heres the thing . I can hand feed until hot then auger will start feeding pellets. sometimes that will not work. . from start blue light works and no yellow light from thermocouple. also using reset button will not work either.

      Our parts manager emailed you direct, just wanted to relay his response here as well. Happy to help anyway we can.

      1)combustion fan running?
      2)call light on?
      3)pressing reset switch interrupts call light?
      4)what year Castile?
      5)control board part number?
      6)how many blue flashes when first plugged in.
      7)wall outlet voltage? GFCI?

    I have a older Quadrafire CB1200, I did my beginning of the heating year clean out of the stove, went to start it up and combustion motor came on but that’s it. The red reset light didn’t come on at first. Paid a little attention to all wire connections and still nota. I then blew on the thermostat on the wall and looked down and red light was on. Auger still didn’t work. Jumped auger wires and direct wired and it and it worked fine. Jumped the vacuum switch, auger still didn’t work. What I do notice is there is a green and red light on the side of the gray control box. Green light stays on Red light keeps flashing. Now I do know I have to replace seals on door because towards the end of last year the stove would put smoke in house on start-up, at times. Once it was going no more smoke. Any suggestions would be great. Is there a way to test control panel?

      Thanks for contacting us Ralph, sincere apologies on the delay here as we didn’t see your message until today. Have you checked the high limit switch in your 1200? If that safety switch trips it will break connection to the auger motor. Yes, gaskets need to be tight around the front door and ash door. It would be rare that these would be so loose that smoke comes out however. Keep in mind that your stove’s firebox is under negative pressure meaning it is always sucking air in. Leaky gaskets can trip the vacuum switch and make for a very lazy inefficient fire so they should be checked every few seasons and it’s good to make sure there is a tight seal all around. Generally speaking if smoke is smelled upon start-up that would be coming from the exhaust. Double check the exhaust to vent pipe connection and all vent pipe connections going out the wall. Make sure you have high temp silicone sealant on each connection point. Have you checked your combustion fan? Should be running near line voltage on start-up and to lock in the vacuum switch. The Control Box can be tested, yes. We do offer a service for testing. Let’s check these other items first before we determine if the board needs to be tested. Keep us posted. Thanks

    Hi, I have a castile had a tech come out and tell me auger motor is bad. Everything worked but not dropping pellets. Bought new motor and replaced myself. Still not dropping pellets. Hit switch on the snaps and still nothing. Blue light blinks, sounds like it starts up but no pellets. Red call light comes on fine. Not sure if I need to replace #3 snap or if its the board????

    • pellethead_admin says:

      Hey Whitney, thanks for contacting us, happy to assist. Both the Vacuum Switch and High Limit switch are in line with the auger motor and can prevent the unit from feeding if they are tripped or faulty. You can bypass these switches 1 at a time for troubleshooting purposes. (Never want to leave a safety switch bypassed). Video links below to assist. Keep us posted with what you find.

      Let’s also make sure the unit and venting is thoroughly cleaned and that the door gasket and ash door gasket are sealing tight all the way around. Ash blockage or weak door seals will trip the vacuum switch. Also, double check your combustion blower – should be running near line voltage on start-up to lock in the vacuum switch.
