The defrost control board is the brain of the outdoor unit's defrost cycle — it monitors coil temperature and run time, then initiates and terminates defrost to clear frost and ice from the outdoor coil during heating operation. It also manages the reversing valve, compressor contactor, and outdoor fan timing. When this board fails, the heat pump can ice over, lose heating capacity, short-cycle, or fail to switch between heating and cooling modes.

This 1\/5 HP motor is the exact factory-spec replacement, matched to the original RPM, rotation, shaft size, and mounting for a straightforward swap.\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\u003e1177593\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eCondenser Fan Motor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar (ICP \/ Heil family)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHorsepower\u003c\/td\u003e\n\u003ctd\u003e1\/5 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrive\u003c\/td\u003e\n\u003ctd\u003eDirect Drive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eOutdoor Condenser Fan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\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\u003eBuilt as the factory-correct condenser fan motor for the Tempstar TXH536GKA200 heat pump.

It monitors outdoor coil temperature and accumulated run time, then starts and stops defrost to clear frost from the outdoor coil during heating. During the cycle the board energizes the reversing valve, switches in auxiliary heat, and times the compressor and outdoor fan. It runs on a 24V control signal and coordinates the contactor, sensors, and reversing valve coil so defrost happens only when conditions require it.

Adequate airflow is critical — a failing fan motor causes high head pressure, poor cooling, compressor overheating, and eventual compressor damage. Motors fail from worn bearings, a burnt winding, or a failed run capacitor.
