It manages the defrost cycle, compressor and reversing-valve timing, anti-short-cycle protection, and the 24V control signals that coordinate the indoor and outdoor equipment. As a complete kit it ships with the board and the mounting\/connector hardware needed for a clean swap. A failed control board is one of the most common causes of erratic heat pump behavior: the unit may stop defrosting and ice over, fail to switch between heating and cooling, short-cycle the compressor, or go completely dead with no response to a thermostat call. Burnt traces, blown relays on the board, scorched connectors, and no LED status activity all point to board failure. This direct-replacement kit restores correct sequencing and protection logic to keep the system running efficiently through every season.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1183618\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eControl \/ Defrost Board Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP (Heil \/ Tempstar \/ Comfortmaker)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncludes\u003c\/td\u003e\n\u003ctd\u003eBoard plus mounting and connector hardware\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM direct replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eEngineered for the ICP \/ Heil \/ Tempstar RHH072L0BA0AAAA heat pump and other RHH072-series outdoor units calling out control board kit P\/N 1183618.
