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.
