Heil Quaker ICP 1185983 Limit Switch
When you are troubleshooting a furnace that is short-cycling or a blower motor that won't kick on, the Heil Quaker ICP 1185983 Limit Switch is a critical safety component to inspect. This OEM replacement furnace limit switch is engineered for precise thermal monitoring within the supply air plenum, featuring a fixed 125-105 temperature range. Functioning as a normally closed safety, it is designed to break the 24V circuit to the gas valve if the heat exchanger exceeds the 125°F high-limit threshold, effectively preventing equipment damage from restricted airflow or oversized firing rates. This specific HVAC high limit sensor is the authenticated direct replacement for the legacy HH18HA525 model, ensuring a drop-in fit with standard mounting brackets found in Arcoaire, Comfortmaker, and Heil systems. For contractors, the ICP 1185983 limit switch offers the reliability required to restore safe furnace operation and maintain correct HVAC system temperature regulation across various residential platforms.
Key Benefits- Precise Thermal Calibration: Fixed 125°F trip point and 105°F reset point ensure consistent furnace safety switch performance.
- Direct Cross-Compatibility: Engineered as the official successor to HH18HA525, eliminating the need for field modifications.
- Simplified Installation: Standard two-wire termination and compact housing allow for fast HVAC part replacement in tight burner compartments.
- Rugged Construction: Built to withstand the high-cycle thermal stress found in modern high-efficiency heat exchangers.
How can I tell if my 1185983 limit switch has failed?
Common symptoms include the furnace burners shutting down before reaching the thermostat setpoint or the blower fan running continuously even when the plenum is cool. Use a multimeter to check for continuity across the terminals when the switch is in its cool state.
What causes this limit switch to trip frequently?
Frequent tripping is usually a symptom of poor airflow. Before replacing the switch, check for a dirty air filter, blocked return air grilles, or a failing blower motor that isn't moving enough CFM across the heat exchanger.
Is the ICP 1185983 compatible with my specific furnace model?
This part is widely used across ICP brands including Heil, Tempstar, and KeepRite. If your original part number is HH18HA525 or 1185983, this is the correct technical match for your equipment.
