Heil Quaker ICP 1173697 Defrost Sensor
The Heil Quaker ICP 1173697 Defrost Sensor is a critical OEM replacement component designed for high-performance heat pump systems. Engineered to monitor the temperature of the outdoor evaporator coil, this sensor triggers the defrost cycle by communicating directly with the defrost control board. It features a specific thermal profile, typically rated at L80-50 or O80 C30, meaning it opens at 80?F and closes at 30?F to ensure efficient frost management. This 3/8-inch sensor identifies ice accumulation and initiates a reversing valve shift to divert warm refrigerant, preventing the outdoor unit from becoming a solid block of ice during low-ambient operation. As a genuine ICP HVAC replacement part, it ensures precise resistance values and electrical compatibility with Heil, Tempstar, Comfortmaker, Carrier, and Bryant equipment. Replacing a drifted or failed sensor restores the unit?s ability to maintain optimal heat transfer and prevents unnecessary compressor strain caused by inefficient defrost termination.
Key Benefits- OEM Compatibility: Exact fit for Heil Quaker, Tempstar, Arcoaire, and Carrier heat pumps, replacing part numbers 1173697 and HH18HA277A.
- System Protection: Prevents excessive ice buildup on outdoor coils, protecting the condenser fan motor and compressor from mechanical stress.
- Precision Calibration: Factory-set O80 C30 thermal limits ensure the defrost cycle initiates and terminates at the exact temperature required for the specific cabinet design.
- Reliable Signal: High-quality thermistor construction provides accurate feedback to the defrost controller, preventing "nuisance" defrost or missed cycles.
How do I know if my defrost sensor is bad?
A faulty sensor often results in a completely frosted-over outdoor coil or the unit staying in defrost mode too long. Technicians should test for continuity and check the resistance against the manufacturer?s temperature-resistance chart.
Will this sensor work with my Comfortmaker unit?
Yes, this 1173697 defrost sensor is a standard component across the International Comfort Products (ICP) family, including Comfortmaker, Day & Night, and KeepRite models.
Where is the 1173697 sensor typically located?
It is usually clipped directly onto the liquid line or a specific circuit of the outdoor coil, where it can best sense the representative temperature of the fins.
