A snap disc, also known as a high-limit switch or a reset switch, is a safety device found in many pellet stoves. It is designed to monitor the temperature inside the stove and shut off the stove's operation if it becomes too hot. If the snap disc is tripped due to overheating, you can reset it to restore normal operation. Here's how you can reset a snap disc on a pellet stove:
Turn Off the Stove: First, ensure that the pellet stove is completely turned off. If it's running, turn it off using the power switch or thermostat.
Locate the Snap Disc: The snap disc is usually located on the back or side of the stove near the heat exchanger or combustion chamber. It is a small, round device with a button or a lever on top.
Wait for Cooling: Allow the stove to cool down for a sufficient amount of time. The snap disc will automatically reset once the temperature drops to a safe level.
Press the Reset Button or Lever: Once the stove has cooled down, locate the reset button or lever on top of the snap disc. Press the button or flip the lever to reset the snap disc.
Check for Smooth Operation: After resetting the snap disc, turn on the pellet stove and observe its operation. Ensure that it functions correctly without any issues.
Monitor Stove Performance: Keep an eye on the stove's temperature and operation to make sure it doesn't overheat again. If the snap disc keeps tripping, there may be an underlying problem with the stove that requires professional attention.
Important Note: If you find that the snap disc continues to trip frequently, or if you notice any other unusual behavior with your pellet stove, it is essential to have it inspected and serviced by a qualified technician. Frequent tripping of the snap disc could indicate a potential safety issue or a malfunction within the stove that needs proper diagnosis and repair. Regular maintenance and servicing of your pellet stove are also essential to ensure its safe and efficient operation.
