Trane HTR15185 Crankcase Heater or the differential between two

or the differential between two points in the air stream

Standard sockets or pliers often fail to engage the specific geometry of the valve cage correctly

This 70W heater is a direct technical substitute for legacy part numbers 02-3653-02S

Industrial Durability: Constructed from high-grade brass with an angleway flow pattern to minimize pressure drop and optimize refrigerant flow

Designed for maximum flexibility

Trane HTR15185 Crankcase Heater or the differential between twoThe Trane HTR15185 Crankcase Heater is a critical component for maintaining compressor reliability, specifically designed to prevent refrigerant migration and oil dilution during the off cycle. This belt type crankcase heater operates at 200 volts and provides a constant 160 watts of heat, ensuring the lubricant remains above the refrigerant saturation point. Engineered as the direct replacement for HTR6623, it is purpose built for Trane HVAC units
