Product description

The Quadrafire 812-3420 Limit Switch is a critical safety control designed to monitor the internal temperature of your heating appliance. This switch acts as a thermal safeguard, automatically breaking the electrical circuit to the stove's fuel feed system or gas valve if temperatures exceed safe operating parameters. By preventing overheating, the limit switch protects the stove's internal components from damage and reduces the risk of hazardous conditions in the home. This switch is calibrated for precise activation and reset temperatures, ensuring that the stove operates within its engineered safety envelope. It is a vital component for the automated safety protocols of Quadrafire pellet and gas stoves. If your stove is shutting down unexpectedly or failing to start, a malfunctioning limit switch may be the cause. Replacing it with this high-quality part ensures your heating system remains safe and reliable.
