A Harman pellet stove not feeding pellets can be frustrating, but it’s a common issue that can often be resolved with a few straightforward steps. In this article, we’ll provide a clear and concise guide to troubleshooting and resolving this problem. Whether you’re a seasoned user or new to pellet stoves, this information will help you get your stove back to optimal performance.
1. Check the Hopper
First, make sure the hopper is not empty. A lack of pellets in the hopper is a common reason for pellet feed issues. Fill the hopper with fresh pellets, and ensure it’s not overfilled, as excessive pellets can lead to jams.
2. Inspect the Auger System
The auger is responsible for moving pellets from the hopper to the burn pot. If it’s jammed or malfunctioning, this can lead to feeding problems. Here’s what you can do:
- Turn off and unplug the stove.
- Open the hopper lid and inspect the auger for any obstructions, such as oversized or clumped pellets.
- Manually rotate the auger to check for smooth movement. If it’s stuck, gently free it from any jams.
- Examine the auger motor for any signs of damage or wear.
3. Clean the Burn Pot
A dirty burn pot can hinder pellet combustion and feeding. To clean it:
- Allow the stove to cool completely.
- Empty any remaining pellets in the burn pot.
- Use a wire brush or scraper to remove ash and residue from the burn pot. Make sure the igniter area is also clean.
4. Verify the Igniter
The igniter is crucial for starting the combustion process. If it’s faulty, it can prevent pellet feeding. Check the igniter by:
- Visually inspecting the igniter for any visible damage.
- Ensure it’s properly positioned in the burn pot.
- If the igniter appears damaged or worn, consider replacing it.
5. Examine the Pressure Switch
The pressure switch is a safety feature that ensures proper ventilation. If it’s not functioning correctly, it can stop pellet feed. Here’s what to do:
- Locate the pressure switch, usually near the exhaust blower.
- Ensure the tubing and connections are free from blockages or damage.
- If the pressure switch is faulty, consult your stove’s manual or contact a professional for replacement.
6. Inspect the Exhaust Blower
A malfunctioning exhaust blower can disrupt the airflow, affecting pellet feeding. Inspect the blower for:
- Signs of damage or blockages.
- Unusual noises or vibrations.
If the exhaust blower is problematic, consider seeking professional assistance or replacing the blower.
7. Consult the Manual
If none of the above steps resolves the issue, consult your stove’s manual for specific troubleshooting advice. You may also consider reaching out to a professional technician for further diagnosis and repair.

A Harman pellet stove not feeding pellets is a common problem that can usually be resolved with some basic troubleshooting.
