Heil Quaker ICP 505962 Limit Switch
The Heil Quaker ICP 505962 Limit Switch is a mission-critical safety component designed for precise thermal regulation in residential furnaces. This 140-160F AUTO limit switch features a bimetal disc that opens the electrical circuit when internal plenum temperatures exceed the 160?F safety threshold, effectively shutting down the burner to prevent heat exchanger damage or hazardous overheating. As the system cools to 140?F, the switch automatically resets, restoring the circuit for normal operation. Engineered as a direct replacement for 626483R, this OEM furnace limit switch ensures drop-in compatibility and maintains the original equipment?s airflow safety parameters. Contractors often utilize this ICP replacement part to resolve furnace short cycling or blower motor continuous run issues caused by a tripped or failing high-limit control. Its snap-action SPST design provides reliable switching under high-amperage loads, making it a staple for maintaining the integrity of Heil Quaker heating systems and other International Comfort Products brands.
Key Benefits for HVAC Professionals
- Direct Fit Compatibility: Seamlessly replaces legacy part number 626483R without bracket modifications.
- Automatic Reset Function: Eliminates manual intervention by resetting once the plenum temperature drops to 140?F.
- Verified Thermal Specs: Precisely calibrated 140-160?F range protects the heat exchanger from thermal stress.
- Plug-and-Play Installation: Standard 1/4-inch terminals and universal mounting flange for fast field replacement.
Common Questions
How do I know if my ICP 505962 limit switch is bad?If your furnace blower runs constantly while the burners won?t ignite, or if the system cycles off before reaching the thermostat setpoint, the limit switch may be stuck open or calibrated incorrectly. Professional diagnosis involves checking for continuity across the terminals when the furnace is cool.
Is the 505962 compatible with other furnace brands?Yes, while marketed under the Heil Quaker and ICP brands, this switch is found in various Kenmore, Tempstar, and Comfortmaker units. Always verify the temperature stamping on the existing switch before installation.
Can I use a higher temperature limit switch if this one keeps tripping?No. Tripping is usually a symptom of restricted airflow, such as a clogged filter or blocked secondary heat exchanger. Standard trade practice dictates addressing the airflow issue rather than bypassing safety limits with a higher temperature rated switch.
