Description
The International Comfort Products 1320363 is an OEM auto-reset high-limit switch engineered to protect furnaces and heating equipment from dangerous overheating conditions. Designed as a direct replacement for compatible ICP, Heil, Tempstar, Arcoaire, and related brand equipment, this limit switch automatically resets once safe operating temperatures are restored — minimizing downtime and service calls.
How It Works
The limit switch continuously monitors heat exchanger or plenum temperatures. When temperatures rise to the upper threshold, the switch opens the circuit to shut down the burner or blower, preventing equipment damage and potential fire hazards. Once temperatures fall back within the safe range, the AUTO function resets the switch without requiring manual intervention.
