It always seems to happen at the worst possible moment. You’re spending a chilly weekend at home, the temperature has dropped, and you decide to fire up your pellet stove—only to find it won’t start. Panic sets in, but don’t worry. Before you reach for extra blankets or call a service technician, here are 11 critical checks that might just save you time and money.
Key Troubleshooting Checks for a Non-Starting Pellet Stove
1. Check the Power Connection
Yes, it sounds obvious, but double-check that the stove is actually plugged in. Inspect the power cable for any damage or cuts. Also, look for any back switches that might have been accidentally turned off.
2. Control Panel Issues
If the stove is electrically connected but the control panel won’t turn on, carefully inspect the control panel’s connections. Check for loose cables or blown fuses. Always disconnect the stove before making any adjustments.
3. Control Panel Alarms
Any alarm codes on the control panel? Consult your user manual to understand what they mean and whether you need professional help.
4. Stove Door
Ensure the stove door is completely closed. Most pellet stoves have a safety mechanism that prevents startup if the door is open.
5. Pellet Supply
Check that there are actually pellets in the hopper. An empty hopper means no fuel, no fire.
6. Auger Function
Verify that the auger (the screw mechanism that moves pellets) is working correctly. If pellets are present but the auger isn’t moving, it might be jammed. This can happen due to wet pellets or debris. You may need to:
- Carefully clear any obstructions
- Use a ash vacuum to remove stuck pellets
- Lubricate the auger (avoiding the motor side)
7. Ignition Resistance
Carefully remove the burn pot and check the ignition electrode. It should glow red-hot during startup. Do not touch it with your hands.
8. Safety Switches
Check for tripped safety switches:
- Reset the safety thermostat if needed
- Look for small reset buttons, typically on the side or back of the stove
- For water-based pellet stoves, check water pressure and circulation pump
9. Exhaust Blower
Test the exhaust blower:
- Ensure it’s not seized (try turning it manually when unplugged)
- Check that it’s receiving power
- Malfunctioning blowers can trigger safety shutdowns
10. Convection Fan
Inspect the convection fan:
- Make sure it turns freely
- Check electrical connection
- A faulty fan can trigger safety thermostats
11. Cleanliness and Maintenance
Poor maintenance can prevent startup or cause unexpected shutdowns. Regular cleaning according to the manufacturer’s instructions is crucial.
Why Might Your Stove Start and Then Stop?
Possible reasons include:
- Running out of pellets
- Forgotten shutdown timer
- Poor pellet quality (high moisture, excessive sawdust)
- Incomplete combustion
- Excessive interior dirt
- Prolonged use without cleaning
Final Advice
If you’ve gone through all these steps and still can’t get your pellet stove running, it’s time to call the manufacturer’s technical support or a qualified technician.
Pro Tip: Keep a maintenance log and perform regular cleaning to minimize startup issues.
