This is a thermal actuator that utilizes an internal wax element

and the unit must be protected from direct weather exposure

Enhanced Protection: High-grade OEM relay components protect sensitive logic boards from back-EMF and short-circuit conditions

providing critical end-stop feedback or the ability to trigger external equipment like pumps or fan coils

Critical Precision: Die-cut dimensions ensure proper seating and eliminate the risk of bypass or extrusion

Tecumseh CCH2C Crankcase Heater 322838-753 This is a thermal actuatorThe Tecumseh CCH2C Crankcase Heater is a critical 240V component designed for refrigeration compressor maintenance to mitigate liquid refrigerant migration during the off cycle. As a veteran grade belly band heater, this 27W 240V element provides regulated thermal energy to the compressor base, ensuring oil remains above the refrigerant's saturation point. This prevents oil dilution and harmful compressor flooded starts, which are primary causes of
