In this concise troubleshooting guide, we’ll provide clear and accurate steps to help you identify and address common problems with Harman pellet stoves. This information is designed to be accessible to both technical and non-technical users.
- No Power or Display
Symptom: The stove doesn’t power on, and the display is blank.
Troubleshooting Steps:
- Check if the stove is plugged in and that the power outlet is working.
- Ensure that any circuit breakers or fuses associated with the stove’s electrical supply are not tripped or blown.
- Inspect the power cord for damage. Replace it if needed.
- Pellets Not Feeding
Symptom: The stove’s auger isn’t feeding pellets into the burn pot.
Troubleshooting Steps:
- Examine the hopper to ensure there are enough pellets. It should not be empty.
- Clean the hopper and remove any pellet fines or debris that might be clogging the feed mechanism.
- Confirm that the auger motor is functioning. You should hear it turning. If not, it may need replacement.
- Poor or No Ignition
Symptom: The stove fails to ignite or has trouble maintaining a fire.
Troubleshooting Steps:
- Ensure that the igniter is clean and functioning. It should glow red-hot during ignition.
- Check the quality of the pellets. Low-quality or damp pellets can impede ignition.
- Inspect the exhaust system for blockages, which can affect airflow and ignition.
- Verify that the safety switches (door switch, exhaust sensor, and overheat switch) are correctly positioned.
- Low Heat Output
Symptom: The stove is running, but it’s not producing sufficient heat.
Troubleshooting Steps:
- Clean the burn pot and heat exchanger. A buildup of ash can reduce heat transfer.

- Frequent Shutdowns
Symptom: The stove frequently shuts down unexpectedly.
Troubleshooting Steps:
- Ensure proper ventilation and fresh air intake. Inadequate airflow can cause overheating and shutdown.
