It includes the high-pressure switch (Part No. 1184656) and the low-pressure switch (Part No. 1184655). These 24V safety switches monitor system refrigerant pressure and open the control circuit to shut the unit down before damage occurs — the high-pressure switch trips on a blocked condenser, overcharge, or failed fan, while the low-pressure switch trips on a refrigerant leak, undercharge, or restricted metering device. Typical failure symptoms include a unit that short-cycles, trips out on safety lockout, or refuses to start because a switch is stuck open. Replacing a faulty switch restores reliable protection and normal operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\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\u003eHigh-Pressure Switch\u003c\/td\u003e\n\u003ctd\u003e1184656\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow-Pressure Switch\u003c\/td\u003e\n\u003ctd\u003e1184655\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eAuto-Reset Refrigerant Pressure Switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar (ICP \/ Heil)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Voltage\u003c\/td\u003e\n\u003ctd\u003e24V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eCompressor High \/ Low Pressure Protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDirect-fit replacement for the Tempstar TSH442GKA101 heat pump and related ICP \/ Heil \/ Comfortmaker units using part numbers 1184656 and 1184655.
