Heil Quaker ICP 1087952 Control Board

The Heil Quaker ICP 1087952 Defrost Control Board is a critical OEM replacement part for managing heat pump defrost cycles in ICP, Heil, Tempstar, and Comfortmaker units. This electronic control board is a direct replacement for the obsolete 1087515 and is technically identical to the CEPL130547-01. It uses a time/temperature defrost logic to prevent ice buildup on the outdoor coil, ensuring your system maintains high performance during the heating season. Designed for robust field performance, the board includes a compressor delay shunt and adjustable interval timing (30, 60, or 90 minutes) to optimize efficiency based on local environmental conditions. When swapping this board, technicians should note it is compatible with the 1172766 defrost sensor, which may be required if the original thermistor is out of 10k ohm spec. This printed circuit board (PCB) is found in a wide range of models, including the CHP060GKC3, CHP036GKC2, and CHC036GHCA series. Its programmed algorithms manage the reversing valve and outdoor fan motor transitions to provide seamless shifts between heating and defrost modes.

• Direct OEM Replacement: Seamlessly replaces legacy part numbers 1087515 and 1087953 for accurate fitment.
• Optimized Cycle Intervals: Features selectable 30, 60, and 90-minute defrost timing to match specific climate demands.
• Enhanced System Protection: Integrated compressor delay prevents short-cycling and reduces mechanical stress during mode transitions.
• Versatile Application: Validated for use across multiple International Comfort Products brands, including Arcoaire and KeepRite.
• Reliable Defrost Logic: Maintains HVAC system efficiency by only initiating defrost when the coil sensor detects freezing conditions.

Is the 1087952 compatible with my older 1087515 board?
Yes, the 1087952 is the official ICP replacement board for the discontinued 1087515 model and offers the same footprint and terminal locations for a straightforward installation.

Does this board include the defrost sensor?
This is the control board only. If you are replacing a failed 1087953, you must also install the 1172766 sensor to ensure the new time/temperature logic functions correctly.

How do I test if the board is initiating a defrost cycle?
You can initiate a forced defrost for diagnostic purposes by shorting the "Speed Up" or "Test" pins with a screwdriver for 5 seconds while the unit is running in heating mode; the reversing valve should shift and the outdoor fan should cycle off.
