Castle Pellet Stove Snap Disc 125 Degree Proof of Fire Switch: 720103-AMP

Replacement Temperature Sensor/ Proof of Fire Switch/ Snap Disc 125 Degrees (52C) for Castle pellet stoves.

This is a thermodisc, or more commonly known as a snap switch. It is what relays to the controller that a fire started in the burn pot and the ignitor can now shut down. If you find that your stove is shutting down shortly after the pellets have begun burning, it may indicate that this switch is faulty.

Troubleshooting Notes

This is a F125-20 made from a ceramic material which is high-heat tolerant. Because it's normally open, it's most often referred to as a fan switch. At ambient room temperature this switch is normally open or OFF and needs to detect heat to CLOSE to allow power to flow through the circuit. The switch will close at 105 degrees to restore power and will return to it's normal state at 125 degrees to cut power automatically. Failure of this switch happens when it stops opening or closing at the designated temperature thresholds.
