Heil Quaker ICP 1085049 Limit Switch
The Heil Quaker ICP 1085049 Limit Switch is a high-precision safety component engineered for furnace high limit protection in residential heating systems. Operating on a normally closed circuit, this 170-30 limit switch is designed to open when temperatures at the heat exchanger reach 170?F, effectively cutting power to the gas valve to prevent thermal damage. This specific ICP furnace part features an automatic reset, re-closing the circuit once the plenum temperature drops to 140?F (a 30?F differential), ensuring the system can resume safe operation without manual intervention. For technicians performing HVAC troubleshooting, this genuine OEM limit switch provides the exact electrical specifications and response times required to maintain internal safety standards in brands like Heil, Comfortmaker, and Tempstar. Its disc-style construction and standard spade terminals allow for a fast furnace repair and seamless integration into existing wiring harnesses.
Key Benefits:
- Critical Overheat Protection: Triggers immediate burner shutdown if the furnace plenum temperature exceeds factory safety thresholds.
- Automatic Reset Logic: Eliminates manual resets by restoring continuity once a safe 140?F cooling point is reached.
- Precise 170-30 Calibration: Maintains a 30?F differential to prevent rapid short-cycling while ensuring robust equipment safety.
- Wide Compatibility: Serves as a direct 1085049 replacement for multiple International Comfort Products (ICP) and Heil Quaker models.
Common Questions:
Why is my furnace short-cycling or shutting down before reaching the set temperature?
A tripped limit switch often indicates restricted airflow caused by a dirty filter, blocked return vents, or a failing blower motor. If the internal heat rises too quickly, the ICP 1085049 will open the circuit to protect the heat exchanger.
How do I test if my 1085049 limit switch is faulty?
Using a multimeter set to continuity, check the terminals while the switch is cool. A functioning switch should show a closed circuit. If it remains open at room temperature, the internal bimetal disc is likely defective and requires a furnace limit switch replacement.
Can I use a higher temperature rated switch if this one keeps tripping?
No. The 170?F rating is a calculated safety limit for your specific furnace model. Installing a higher limit can lead to cracked heat exchangers and dangerous operating conditions.
