Tecumseh CCH2C Crankcase Heater 322838-753 Common signs include the inducerThe 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
