Overview
This is a genuine OEM crankcase heater thermostat (part #14124800, "TSTAT CC HTR 75/55") for the ICP / Tempstar / Heil YD024GA condensing unit. It is a temperature-sensing bimetal snap-disc switch that energizes the compressor crankcase heater in cold weather to keep refrigerant from migrating into and condensing in the compressor oil. The "75/55" rating means the contacts cycle across the 55°F–75°F band so the heater operates only when needed, preventing both energy waste and cold-start liquid slugging. When this thermostat fails, the crankcase heater either stays on continuously (overheating the oil and wasting power) or never comes on (allowing refrigerant flooding, hard starts, and premature compressor wear). It is an inexpensive part that protects an expensive compressor.

- Install — Mount the new thermostat in firm contact with the crankcase and reconnect the leads per your photo.
- Test — Restore power and confirm the crankcase heater energizes in cold ambient and de-energizes as the disc warms.
