Heil Quaker ICP 1173821 Defrost Sensor
The Heil Quaker ICP 1173821 Defrost Sensor is a critical OEM replacement component engineered for precision evaporator coil temperature monitoring in residental and commercial heat pumps. Designed for high-accuracy frost accumulation detection, this sensor measures the thermal state of the outdoor coil to signal the defrost control board when it is time to initiate or terminate a defrost cycle. By ensuring that the unit only enters defrost mode when necessary, it optimizes heating cycle efficiency and prevents energy loss associated with unnecessary reversing valve shifts.
This ICP 1173821 sensor is built to withstand extreme outdoor environments, maintaining a consistent resistance-to-temperature curve essential for HVAC system diagnostics. It a direct-fit for various International Comfort Products brands, including Heil, Tempstar, and Comfortmaker. For technicians troubleshooting heat pump icing issues, replacing a drifting or failed sensor with this genuine 1173821 defrost thermistor is the standard procedure to restore factory-spec refrigeration cycle performance and protect the compressor from liquid slugging during blocked-coil conditions.
Key Benefits:
- Ensures precise defrost cycle initiation to prevent heavy ice buildup on outdoor coils.
- Maintains OEM HVAC compatibility for seamless integration with ICP control boards and wiring harnesses.
- Optimizes system energy efficiency by reducing runtime in cooling mode during the defrost process.
- Durable construction designed to resist moisture and thermal cycling stress common in heat pump applications.
Common Questions:
How do I test if my defrost sensor is faulty?
Using a multimeter set to ohms, measure the resistance across the sensor leads and compare the reading to the manufacturer?s temperature-resistance chart. If the sensor shows an open circuit (OL) or a resistance value that does not correspond to the actual coil temperature, the part should be replaced.
What are the symptoms of a failing ICP 1173821 sensor?
A failed sensor often leads to an outdoor coil completely encased in ice or a system that stays in defrost mode too long, causing the indoor supply air to drop significantly in temperature during the heating call.
Can I use this sensor on other ICP sub-brands?
Yes, this is a universal OEM part for the ICP family, which includes brands like Arcoaire, Keeprite, and Day & Night, provided the part number matches the original equipment specifications.
