Heil Quaker ICP 1185984 Limit Switch
The Heil Quaker ICP 1185984 Limit Switch is a high-precision thermal safety component essential for maintaining the operational integrity of residential and commercial HVAC units. Engineered by International Comfort Products (ICP), this L135-115 manual reset limit switch acts as a critical line of defense, monitoring the heat exchanger temperature and preventing safe thresholds from being exceeded. When airflow is restricted due to a clogged filter or a failing furnace blower motor, the 1185984 interrupts the ignition circuit, effectively preventing heat exchanger damage and potential safety hazards. This OEM ICP limit switch features a 135-degree Fahrenheit trip point (open) and is designed to reset at 115 degrees Fahrenheit, ensuring precise cycling and system reliability. For technicians performing furnace troubleshooting, this switch is the standard replacement to resolve common issues such as short cycling or a blower fan that refuses to shut down. Its robust construction ensures long-term performance under high-static conditions typical of older Heil Quaker furnace models.
Key Benefits for Contractors- Precision Thermal Calibration: Features a fixed 135?F open and 115?F close differential to ensure system protection without premature tripping.
- Direct OEM Compatibility: Verified ICP 1185984 cross-reference part for Heil, Quaker, Tempstar, and Comfortmaker equipment.
- Enhanced Safety: Effectively monitors for overheating conditions caused by restricted airflow or mechanical failure.
- Rugged Housing: Built to withstand commercial-grade vibration and thermal stress within the furnace cabinet.
Why is my furnace short cycling with a new 1185984?
If the limit switch trips shortly after ignition, verify the air filter condition and check for blocked return air ducts. High static pressure is the most common cause for the 1185984 to open the circuit.
Will this switch fix a blower that won't turn off?
Yes, if the internal contacts of the original HVAC limit control have fused or reached high resistance, the fan may run continuously to cool the heat exchanger. Replacing the faulty switch usually restores standard fan timing.
Is this compatible with 115-volt and 24-volt systems?
The 1185984 limit switch is primarily designed for the 24VAC safety pilot or ignition control circuit but is rated for the electrical loads typical of ICP-branded gas furnaces.
