It monitors discharge-line pressure and opens the low-voltage control circuit if pressure climbs to an unsafe level, shutting the compressor down to prevent damage. High-pressure trips are commonly triggered by a dirty condenser coil, a failed condenser fan, an overcharge, or a restriction — but the switch itself can also fail open, stick closed, or drift out of calibration, causing nuisance lockouts or, worse, defeating the safety entirely.\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\u003e1184656\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHigh Pressure Limit Switch (auto-reset)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eRefrigerant safety cutout\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit\u003c\/td\u003e\n\u003ctd\u003e24V control (normally closed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eSpecified for the Tempstar TCA724GKA100 condensing unit and shared across many ICP-family outdoor units sold under the Tempstar, Heil, Comfortmaker, and Carrier\/Bryant ICP labels.
