Ensure the safety and reliability of your furnace with the Goodman / Amana 10728319 Limit Switch (L170‑40F). This OEM thermal cutoff device is carefully engineered to open at approximately 170 °F (with a 40 °F reset differential), protecting your system from overheating and preventing damage to internal components.
Features:
- Overheat Protection — Prevents furnace damage by cutting off heat when temperatures exceed safe limits.
- Replacement for Faulty Switches — Use when the existing limit switch is open permanently, trips too often, or fails diagnostics.
- Safety Component in Furnace Overhauls — A critical part in maintenance kits for service technicians to restore safety functionality.
