Many factors can prevent a pellet stove from igniting, some common causes include poor-quality pellets, airflow obstructions, or a faulty igniter. But before you call a technician, there are simple things you can try yourself to make your stove work again.
Common Causes of Pellet Stove Ignition Failure
Pinpointing the culprit behind a non-igniting pellet stove is essential for getting it back up and running. Let's examine the most frequent causes:
Bad Pellets
Moisture is the enemy of good ignition. Damp or wet pellets will smolder and struggle to produce a sustainable flame. Additionally, excessive sawdust or low-quality pellets can create feeding issues or fail to burn hot enough.
Airflow Problems
Pellet stoves need proper airflow for combustion. Obstructions in several areas can limit this airflow:
- Air Intake: Check for blockages where outside air enters the stove.
- Venting: Ensure the exhaust vent isn't clogged by debris, creosote buildup, or even a bird's nest.
- Exhaust Blower: A malfunctioning exhaust blower won't create the necessary draft to pull air through the stove.
- Burn Pot: Excess ash buildup in the burn pot can choke airflow and hinder pellet ignition.
Faulty Igniter
The igniter is the heating element that starts the fire. A broken or worn-out igniter won't get hot enough to light the pellets. Signs of trouble include no visible glow or a cracked igniter element.
Other Potential Issues
While less common, these factors can also cause ignition problems:
- Power Supply: An intermittent power supply or faulty outlet can prevent the stove from starting.
- Control Board Malfunctions: Issues with the control board may disrupt the ignition sequence.
- Safety Sensors: Tripped pressure switches or other safety sensors can also prevent ignition.

Step-by-Step Troubleshooting
Before diving into complex fixes, let's cover the basics and then work our way through a logical troubleshooting process. Remember, always prioritize safety! Unplug your stove before performing any internal checks.
Step 1: Check the Basics
- Power: Is the stove plugged in and switched on? Is there power at the outlet?
- Pellets: Make sure the hopper has enough pellets for ignition.
- Ash: Remove excessive ash build-up from the burn pot.
Step 2: Inspect the Pellets
- Moisture: Look for signs of water damage or dampness. If the pellets feel wet or have been stored in a humid area, replace them.
- Quality: Check for excessive sawdust or crumbling pellets. Opt for high-quality pellets designed for pellet stoves.
Step 3: Examine Airflow
- Air Intake: Clean any blockages from the external air intake pipe or vent.
- Venting: Inspect the exhaust vent for obstructions like debris, nests, or creosote buildup. Have it cleaned if necessary.
- Internal Components: Remove internal baffles or covers (refer to your owner's manual) and clean out any ash or debris from airflow pathways.
- Exhaust Blower: Ensure the blower is spinning freely and there are no unusual noises.
Step 4: Test the Igniter
- Visual Inspection: When your stove attempts to start, look for the igniter element glowing red hot. A lack of glow can indicate a problem.
- Resistance Testing (if applicable): Some igniters allow you to test their resistance with a multimeter. Your owner's manual will provide the correct resistance range for your stove's igniter.
Step 5: When to Call a Professional
- Safety: If you're uncomfortable with electrical components or complex stove disassembly, don't hesitate to call a technician.
- Control Board: Issues with the control board or wiring often require professional assistance.
- Persistent Problems: If troubleshooting doesn't solve the issue, a technician can diagnose and fix the underlying cause.
