Heil Quaker ICP 1186801 Limit Switch
The Heil Quaker ICP 1186801 Limit Switch is a critical safety component designed for high-performance furnace repair and system protection. This OEM furnace limit switch operates on a 190-150 temperature scale, meaning it is a normally closed switch that opens (trips) at 190?F to prevent heat exchanger damage and automatically resets when the plenum temperature drops to 150?F. As a veteran-grade HVAC replacement part, it ensures the unit remains within safe thermal operating parameters, preventing a furnace short cycling condition or total system lockout.
Engineered for seamless compatibility across International Comfort Products (ICP) brands, including Heil, Tempstar, and Comfortmaker, this 190-150 limit switch features a 2.75-inch insertion length. It serves as a direct furnace high limit switch replacement for various N95ESN and R9MSB series models. When troubleshooting a furnace blower running constantly or a unit that won't blow hot air, verifying the continuity of the 1186801 limit switch is a standard diagnostic step for any field technician.
Key Benefits for Technicians:
- Direct OEM Replacement: Ensures precise drop-in fitment for ICP furnace parts without the need for mounting modifications.
- Automatic Reset Function: Eliminates manual resets by re-engaging the heating circuit once the 150?F threshold is met.
- Safety Compliance: Maintains original agency listings and safety standards for the furnace's thermal protection circuit.
- Durable Construction: Built to withstand the high-cycle demands of modern heating and cooling systems.
Common Questions:
How do I know if my furnace limit switch is bad?
Common signs include the system shutting down before the thermostat is satisfied, the blower fan running continuously even when the burners are off, or a diagnostic code indicating an open high-limit circuit.
Can I use a universal switch instead of the ICP 1186801?
While some universal parts exist, using this specific OEM 1186801 switch ensures the timing, probe length, and temperature differentials match the manufacturer?s original engineering specifications for safety.
What causes a limit switch to trip frequently?
Frequent tripping is often caused by restricted airflow, such as a clogged furnace filter, blocked return air vents, or a failing blower motor, rather than a faulty switch itself.
