Technical Details
Before diving into troubleshooting, let’s familiarize ourselves with some essential technical details of Lennox pellet stoves:
Ignition System:
- Lennox pellet stoves typically use an automatic ignition system that ignites the pellets.
- The igniter, combustion fan, and auger motor are key components of the ignition system.
Fuel Supply:
- Pellet stoves rely on a consistent supply of quality pellets.
- The hopper stores the pellets, and an auger feeds them into the burn pot for combustion.
Exhaust and Ventilation:
- Proper ventilation is essential to ensure safe and efficient operation.
- Lennox stoves utilize a venting system, including an exhaust pipe and air intake, to maintain proper airflow.
Control Panel:
- The control panel allows you to set the desired temperature and control various functions.

Troubleshooting Steps
Now, let’s proceed with the troubleshooting steps for common issues with Lennox pellet stoves:
No Ignition:
- If the stove is not igniting, check the igniter for damage or malfunction.
- Ensure the hopper is filled with dry pellets, as damp pellets can affect ignition.
Poor Pellet Feeding:
- If the auger is not feeding pellets properly, inspect it for blockages or damage.
- Ensure the pellets in the hopper are not clumped together, as this can impede feeding.
Low Heat Output:
- If the stove is not producing enough heat, clean the burn pot and heat exchanger.
- Check the air intake and exhaust for obstructions that may affect combustion.
Excessive Smoke:
- Excessive smoke can be a sign of poor combustion. Check for obstructions in the venting system and ensure the air intake is clear.
- Verify that the combustion fan is functioning correctly.
Error Codes:
- If the control panel displays an error code, consult your stove’s manual to identify the issue.
- Some error codes may indicate specific problems like a blocked exhaust pipe or a faulty sensor.
Routine Maintenance:
