Trane HTR1225 Crankcase Heater 320788-703 As a veteran-grade service replacementThe Trane HTR1225 Crankcase Heater is a critical component for maintaining compressor reliability, specifically designed to prevent refrigerant migration during equipment off cycles. This insertion type crankcase heater operates at 230 volts and provides 60 watts of regulated heat, ensuring the compressor oil stays above the refrigerant's saturation point. Maintaining this temperature differential prevents liquid refrigerant from condensing in the
