QuadraFire 2.4 RPM feed motor for most pellet stoves and inserts. This part is commonly called an auger motor. Includes the motor, mounting bracket, capacitor bypass wire adaptor (for use on some models made prior to 2006), and instructions.

This motor does not come with a mounting bracket. If you cannot use your old bracket please order the whole assembly to avoid compatibility issues.

Older Models made prior to 2006

  • CB1200 and Contour, and Mt Vernon (OM) models still using the gray, opaque control boxes may require the use of the adapter bypass wire included with this motor. If your motor can plug into the existing wiring connection the adapter is not used.

Note: The Edge60 Built-in and the Mt Vernon AE Pellet Stove/ Insert use a 12 volt auger feed motor, SRV7000-313.

This motor runs on line voltage which will be roughly 115v. The yellow square mounted to the motor assembly is a capacitor, which is used to flip the polarity of the motor if the motor is under strain from a jam. If this happens, the motor will temporarily reverse the spin the auger, freeing the jam, when the capacitor cools, the polarity will be restored to the correct direction and feeding will resume.

If your stove is not feeding but the motor is turning, you may be turning backwards.

  • the capacitor will reverse polarity if the heat from the stove is warming the capacitor. Make sure the wires are hanging from the proper mounts and not hanging on top of the exhaust blower.
  • When testing the auger, there MUST be at least 1lb of pellets in the hopper to close the pressure switch under normal conditions

If your stove will not feed:

  1. Unplug the appliance, remove the control box, re-install the control box, and plug the appliance back in. A blue light should blink once to six times. Verify these blinks against your stove and set the program accordingly. See Control Box Programming.
  2. Turn on stove, verify the exhaust blower is "ON"
  3. Turn on the thermostat - the thermostat indicator light should come on and feed cycle should start.
  4. If the feed system does not come on: – Check the vacuum switch – Check the hopper switch (if equipped) - Check the wire harness – Replace #2 snap disc.
