A pellet stove’s auger is a critical component responsible for feeding pellets into the combustion chamber. If you encounter an issue with the auger not spinning, it can disrupt the stove’s operation and leave you in the cold. In this article, we will dive into the technical aspects of pellet stove augers and explore common reasons for this problem and how to fix it.
Understanding the Pellet Stove Auger
The pellet stove auger is a mechanical screw device designed to transport wood pellets from the hopper to the burn pot. It regulates the fuel supply, ensuring a consistent and efficient burn. A malfunctioning auger can lead to reduced heat output or even stove shutdown.
Troubleshooting Steps
Check for Jammed Pellets:
The most common reason for a non-spinning auger is a pellet jam. To resolve this issue:
- Turn off the stove and unplug it to ensure safety.
- Open the hopper and remove any remaining pellets.
- Inspect the auger area for blockages. If you find jammed pellets, use a long tool like a dowel or a vacuum cleaner to clear them. Ensure the auger turns freely by hand.
Inspect the Motor:
If you’ve ruled out pellet jams, the problem may lie with the motor that drives the auger. To check the motor:
- Ensure the stove is unplugged.
- Disconnect the motor wires and use a multimeter to test for continuity. If there’s no continuity, it may be a sign of a faulty motor that needs replacement.
Examine the Control Board:
Sometimes, the control board may be the culprit if it’s not sending the right signals to the auger motor. To examine the control board:
- Inspect for any visibly damaged or burnt components.
- Check for loose connections.
- If you suspect an issue with the control board, it might be a good idea to consult a professional technician or replace the board if you’re experienced and confident.
Auger Motor Reset:
Some pellet stoves have a built-in safety mechanism that can trip the auger motor. If the motor gets too hot, it may need to be manually reset. This usually involves pressing a reset button on the motor itself. Refer to your stove’s manual for specific instructions.
Lubricate the Auger:
Over time, pellet dust and residue can cause the auger to become sticky. Lubricating the auger with a food-grade or high-temperature grease can often resolve this issue. Ensure the stove is off and cooled before attempting to lubricate the auger.
Conclusion
A pellet stove auger that’s not spinning can be a frustrating issue, but with some basic troubleshooting, you can often identify and resolve the problem. Remember to prioritize safety by turning off and unplugging the stove before attempting any maintenance or repairs. If you’re unsure or the issue persists, it’s advisable to seek assistance from a professional technician to ensure your pellet stove operates efficiently and safely.
