Heil Quaker ICP 1178677 Temp Switch
As an experienced technician, you know that a failed defrost cycle is the fastest way to lose a compressor. This Heil Quaker ICP 1178677 Defrost Temp Switch is a precise OEM replacement part designed to monitor outdoor coil temperatures and signal the control board to initiate or terminate the defrost sequence. Featuring 50-1/2 inch long leads, this temperature sensor offers the lead length necessary for clean routing on various International Comfort Products (ICP) heat pumps and packaged units, including the PDS4 series and PDD3 models. This switch functions as a defrost sensor that closes at specific low-ambient thresholds?typically around 32?F?to prevent ice accumulation from insulating the coil and dropping system COP. For contractors, using a genuine ICP 1178677 switch ensures the "speed-up" test on the defrost board provides accurate diagnostic feedback, maintaining the factory-specified balance between energy-efficient heating and essential coil protection without the risk of early termination or stuck-closed failures common with generic thermistors.
Key Benefits for the Jobsite:- Exact OEM Logic: Designed specifically for ICP and Heil Quaker systems, ensuring the defrost board receives the correct resistance or continuity signals.
- Extended Service Leads: The 50-1/2" lead length allows for versatile mounting locations on larger coils without needing to splice or extend wiring.
- Optimized Heat Pump Efficiency: Prevents "nuisance defrosting" by accurately sensing coil saturation, preserving the unit's heating capacity during cold/damp transitions.
- Rugged Seal Design: Engineered to withstand the constant thermal cycling and moisture exposure inherent to outdoor evaporator coils.
When should this switch be replaced?
Replace the 1178677 switch if you observe excessive ice buildup on the outdoor coil that the board fails to clear, or if the unit gets stuck in defrost mode. Always check for a "closed" status when the coil is frosted and an "open" status when the coil is warm.
Is this compatible with multiple brands?
Yes, this ICP temperature switch is the correct HVAC replacement part for brands under the International Comfort Products umbrella, including Heil, Quaker, Tempstar, Comfortmaker, and KeepRite.
Why is the lead length important?
With 50.5-inch leads, this part covers a wide range of cabinet sizes. Shorter leads often require field splicing, which introduces high-resistance points that can skew the defrost sensor readings and cause timing errors.
