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.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverheat Protection:\u003c\/strong\u003e Shuts down the system if temperatures reach unsafe levels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Interlock:\u003c\/strong\u003e Crucial for preventing structural damage to the heating unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise Calibration:\u003c\/strong\u003e Engineered for exact temperature-dependent switching.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable Sensing:\u003c\/strong\u003e High-quality thermal disc for consistent performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEssential Component:\u003c\/strong\u003e A primary safety feature in Quadrafire appliances.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Quadrafire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 812-3420\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Thermal Limit Switch \/ Snap Disc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overheat Safety Sensing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eReplacement limit switch for Quadrafire systems requiring part 812-3420.\u003c\/p\u003e\u003cp\u003eYou will receive the same product or an OEM-Equivalent that meets the highest standard of the OEM with warranty that will be a direct-fit.
