Heil Quaker ICP 1186810 Limit Switch
The Heil Quaker ICP 1186810 Limit Switch is a critical safety component designed for precise thermal monitoring in high-efficiency gas furnaces and air handlers. Engineered with a 165-degree Fahrenheit open temperature and a 125-degree Fahrenheit close temperature, this L165-40 manual reset switch prevents heat exchanger overheating by breaking the electrical circuit to the gas valve when temperatures exceed safe operating limits. This OEM replacement limit switch ensures compatibility with specific ICP, Heil, and Tempstar units, maintaining the original equipment manufacturer's airflow and safety specifications. As a fixed-temperature furnace safety switch, it provides reliable flame rollout or over-temp protection, reducing downtime and preventing hazardous operating conditions. Contractors should verify the limit switch differential and mounting configuration to ensure a seamless drop-in installation during HVAC system troubleshooting or preventative maintenance.
Key Benefits for Technicians:- OEM Precision: Direct ICP 1186810 replacement ensures exact thermostatic response times and electrical ratings.
- Safety Compliance: Features a 165-125 temperature range to protect the heat exchanger from thermal stress and potential failure.
- Durability: Constructed with high-grade bimetal sensing elements for consistent performance in high-cycle environments.
- Direct Fit: Standardized mounting footprint reduces field modification time during emergency service calls.
What causes a Heil Quaker limit switch to trip frequently?
Repeated tripping usually indicates restricted airflow, often caused by a dirty air filter, blocked return ducts, or a failing blower motor. If the switch remains open despite normal temperatures, the internal bimetal disc may have fatigued, requiring a full replacement.
Is the ICP 1186810 a manual or automatic reset switch?
This specific model is designed as a fixed-temperature limit switch. Engineers and technicians must confirm the specific suffix of the part number to determine if the application requires a manual reset or if the circuit re-closes automatically once temperatures drop to 125 degrees.
Can I use a higher temperature limit switch if this one keeps tripping?
No. Safety limits are strictly calibrated to the furnace's heat exchanger rating. Installing a switch with a higher opening temperature than the 165-degree spec can lead to equipment damage or fire hazards.
