Heil Quaker ICP R02R007 Limit Switch
The Heil Quaker ICP R02R007 Limit Switch is a critical safety component designed for high-limit temperature monitoring in residential and light commercial HVAC units. Engineered with a 120-20F temperature rating, this SPST (Single Pole Single Throw) fixed-setting switch is designed to open the electrical circuit at 120?F and reset once temperatures drop by a 20?F differential. This ensures precise furnace high limit protection by preventing the heat exchanger from overheating during restricted airflow or blower failure conditions. As an OEM replacement part, the R02R007 is compatible with various Heil, Quaker, International Comfort Products (ICP), and Comfortmaker air handlers and furnaces. For service technicians, this snap-disc limit control provides a reliable, drop-in solution for restoring system safety protocols. Proper installation requires verifying mounting flange alignment to ensure accurate sensing of the internal plenum temperature during the heating cycle.
Key Benefits for Technicians- Precise Thermal Calibration: Factory-set to trip at 120?F with a 20?F reset differential for consistent safety cycles.
- Broad ICP Compatibility: Direct replacement for multiple Heil Quaker limit control iterations, ensuring exact fit and function.
- Industrial-Grade Construction: Built to withstand high-cycling environments without premature contact fatigue.
- Critical Safety Compliance: Restores UL-rated safety limits to older and modern furnace architectures.
- Simplified Field Service: Standard two-pin terminal configuration allows for rapid diagnostic testing and replacement.
What causes this limit switch to trip repeatedly?
Frequent tripping usually indicates restricted airflow, such as a clogged MERV-rated filter, a failing blower motor, or obstructed return air ducts causing the plenum to exceed 120?F.
Can I bypass this switch for testing?
Temporary bypassing is only for immediate diagnostic continuity checks. The R02R007 must be operational during furnace runtime to prevent heat exchanger damage or fire hazards.
Is this an auto-reset or manual-reset switch?
This is an automatic reset limit switch. Once the temperature falls back below the reset threshold (approx. 100?F), the internal bimetal disc will snap back to the closed position.
