The International Comfort Products 1185236 control board serves as the primary electronic control center for select residential heat pump units. Branded across major Carrier corporations including Keeprite, Heil, Comfortmaker, and Tempstar, this direct replacement circuit board is essential for coordinating communication between indoor thermostats and the outdoor compressor.
This factory-certified control board manages vital refrigeration system operations, specifically targeting reversing valve activation, defrost cycle sequencing, and compressor safety timers. The integrated circuit continuously monitors electrical inputs from pressure switches and ambient sensors, executing emergency system shutdowns if unsafe parameters are detected to shield heavy hardware from catastrophic mechanical wear.
Replacing older legacy part number 1184601, this component fits a broad array of split systems, notably the CSH418GKA101, CSH424GKA101, CSH430GKA101, CSH436GKA101, and CSH442GKA101 models. HVAC contractors depend on this precise OEM part to correct erratic heating or cooling behaviors. Ensure total power disconnect and verify technical compatibility specs before starting the wiring installation.
