Rated to switch at approximately 75°F \/ 55°F, it energizes the crankcase heater when outdoor\/compressor temperatures drop and de-energizes it once the compressor warms up. The crankcase heater keeps refrigerant from migrating to and condensing in the compressor oil during cold standby — preventing oil dilution, foaming, and slugging at startup that can destroy a compressor. When this thermostat fails open, the heater never runs and the compressor is exposed to liquid migration in cold weather; when it fails closed, the heater runs continuously and wastes energy. It is a small, inexpensive component that protects a very expensive one.\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\u003e14124800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eCrankcase Heater Thermostat \/ Temperature Switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Tempstar \/ Heil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitch Point\u003c\/td\u003e\n\u003ctd\u003e75°F \/ 55°F (close\/open)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eCompressor Crankcase Heater Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eDirect OEM replacement for the ICP \/ Tempstar \/ Heil YD018GA and other ICP-family units that specify the 14124800 crankcase heater thermostat.
