Pellet stoves are known for their efficient and eco-friendly way of heating homes. However, like any appliance, they can occasionally encounter issues, including control board malfunctions. In this article, we will guide you through the process of bypassing the control board on a pellet stove. Whether you’re a seasoned technician or a homeowner, understanding this procedure can be a valuable skill in case of emergencies.
Disclaimer: Bypassing the control board should only be considered a temporary solution or for diagnostic purposes. If your control board is faulty, it’s best to replace it to maintain the safe and efficient operation of your pellet stove.
Understanding the Control Board
The control board in a pellet stove is essentially the "brain" of the appliance. It manages various functions, including ignition, pellet feed rate, and temperature control. When the control board malfunctions, it can disrupt the stove’s operation, leading to a lack of heat or even preventing it from running altogether.
Steps to Bypass the Control Board
Bypassing the control board means taking over its functions manually to keep the pellet stove operational. Here’s how to do it:
Safety First: Before attempting any procedure on your pellet stove, ensure it is unplugged and cooled down. Safety should always be a priority.
Locate the Control Board: The control board is typically located within the stove’s housing. You may need to remove panels to access it. Refer to your stove’s manual for guidance.
Identify the Key Components: The control board controls the auger motor and the combustion fan. To bypass it, you’ll need to identify these components and their wiring.
Auger Motor Bypass:
- Disconnect the wires leading from the control board to the auger motor.
- Connect the auger motor directly to a power source (usually 110-120V) to start pellet feed. Be cautious and ensure you have a safe connection.
Combustion Fan Bypass:
- Disconnect the wires leading from the control board to the combustion fan.
- Connect the combustion fan directly to a power source to ensure it runs for proper air circulation.
Monitor the Stove: With the auger motor and combustion fan manually connected, the pellet stove should operate as intended. You can control the heat output by adjusting the rate of pellet feed manually.
Temperature Control: You’ll need to regulate the stove’s temperature manually by adjusting the pellet feed rate. Experiment and monitor the stove to maintain the desired room temperature.
Consider a Replacement: While bypassing the control board can keep your stove operational in the short term, it’s crucial to replace the control board to ensure safety and long-term reliability.
Conclusion
Bypassing the control board on a pellet stove can be a valuable skill in case of emergencies or for diagnostic purposes. However, it should only be considered a temporary solution. A malfunctioning control board should be replaced to ensure the safe and efficient operation of your pellet stove. If you’re not comfortable performing these steps or if the issue persists, it’s advisable to seek professional assistance to address the underlying problem and maintain the integrity of your pellet stove.
