Heil Quaker ICP R02R003 Limit Switch
As a field tech, you know that a failed high limit switch is often the first symptom of deeper airflow issues in a furnace. The Heil Quaker ICP R02R003 Limit Switch is a critical safety component designed for International Comfort Products (ICP) equipment, including Heil, Quaker, and Tempstar systems. This OEM replacement part is engineered for a 165-195F temperature range, featuring an auto-reset mechanism that opens the circuit when the heat exchanger nears 195°F and closes it at 165°F to restore operation. With a 1.75-inch insertion length, it ensures accurate sensing within the plenum. Whether you are troubleshooting furnace short cycling or a blower motor running constantly, this Heil Quaker limit control provides the precise thermal response required to protect the heat exchanger from cracks and overheating. Relying on genuine ICP parts like the R02R003 ensures the system stays within its original design specifications for safe, reliable operation during peak demand.
Key Benefits for Technicians:
- Precision Thermal Calibration: Calibrated for a 195°F open and 165°F close to prevent heat exchanger damage.
- Direct OEM Fit: Specifically designed for ICP furnace models like AMT112SDMA and OLR112A16A, eliminating mounting issues.
- Automatic Reset Logic: Features an auto-reset limit switch design that restores power once safe temperatures are reached.
- Standard Insertion Depth: The 1.75" insertion probe provides accurate monitoring of supply air temperature.
- Broad Compatibility: Functions as a direct cross-reference for various Heil Quaker and Carrier oil and gas furnaces.
Common Questions for HVAC Pros:
What causes an ICP R02R003 to trip frequently?
Repeated tripping is usually caused by restricted airflow, such as a clogged filter, a dirty evaporator coil, or a malfunctioning blower motor. If the switch trips too often, the internal bimetal disc can fatigue, requiring a limit switch replacement.
Can I use a different temperature-rated switch?
No. Using a switch with a higher opening temperature than the R02R003 can lead to dangerous internal heat levels and potential fire hazards. Always match the OEM temp specs and insertion length.
How do I test this limit switch for continuity?
With the power off and the part at room temperature, use a multimeter to check for continuity across the spade terminals. A functioning ICP R02R003 should show a closed circuit (0 ohms) under 165°F.
