A pellet stove is a reliable and efficient heating appliance, but like any mechanical device, it can encounter issues. One common problem that users face is when the igniter on a pellet stove stays on continuously. In this article, we’ll explore the potential causes of this issue and provide straightforward solutions for both technical and non-technical users.
The Role of the Igniter
The igniter in a pellet stove serves a vital function – it’s responsible for starting the combustion process. When you turn on your pellet stove, the igniter heats up to ignite the pellets in the burn pot, kick-starting the heating process. Once the fire is established, the igniter should turn off to prevent overheating and excessive energy consumption.
When the Igniter Stays On
If you find that the igniter on your pellet stove remains on even after the pellets have ignited, several factors might be contributing to this problem:
1. Faulty Temperature Sensor:
The most common reason for a continuous igniter operation is a malfunctioning temperature sensor. The temperature sensor is responsible for monitoring the heat level in the burn pot. If it fails to detect the temperature correctly, it may cause the igniter to stay on. Replacing the temperature sensor is the solution in this case.
2. Ignition Failure:
Sometimes, the pellets may not ignite properly due to issues like clogged burn pots or poor-quality pellets. In such cases, the stove’s control unit might not receive the signal that the fire is lit, causing the igniter to remain active. Ensure your burn pot is clean and use high-quality pellets to avoid this issue.
3. Control Board Malfunction:
The control board of your pellet stove is the brain behind its operations. If it malfunctions or experiences a software glitch, it can keep the igniter on longer than necessary. Try rebooting the stove by turning it off and on. If the problem persists, consider replacing the control board.
4. Auger Jam:
An auger jam, which is responsible for feeding pellets into the burn pot, can cause an extended igniter operation. If the auger is blocked or not functioning correctly, it can lead to delayed ignition. Ensure the auger mechanism is clean and functioning properly.
Troubleshooting and Solutions
Here are steps you can take to address the issue of a pellet stove igniter that stays on:
Check the Temperature Sensor: Inspect the temperature sensor for any signs of damage or malfunction. If it’s not functioning correctly, replace it following the manufacturer’s guidelines.
Clean the Burn Pot: Ensure the burn pot is clean and free from blockages that might prevent the pellets from igniting properly.
Examine the Control Board: Reboot the stove and check if the igniter turns off after a short time. If not, consider consulting a professional to diagnose and replace the control board if needed.
Auger Inspection: Inspect the auger for any blockages or malfunctions. Ensure it’s clean and moving smoothly.
Quality Pellets: Always use high-quality pellets to avoid ignition problems. Poor-quality pellets can lead to ignition failures.
Final Thoughts
A pellet stove igniter that stays on continuously is a common issue, but it’s usually solvable with some basic troubleshooting. Start with the temperature sensor and proceed to examine other components, such as the control board and auger. Always follow your stove’s user manual and safety guidelines when performing maintenance or repairs. If you’re unsure about any of the procedures, consider seeking professional assistance to ensure your pellet stove operates efficiently and safely.
