The Trane HTR2444 is a genuine OEM crankcase heater designed to protect compressor longevity and reliability in residential and commercial HVAC systems. Operating at 120 volts and 150 watts, this crankcase heater maintains the compressor oil temperature during off cycles, preventing refrigerant from migrating into and mixing with the compressor oil — a leading cause of premature compressor failure.
Why Crankcase Heaters Matter
During extended off periods or cold ambient conditions, liquid refrigerant can migrate to the compressor crankcase and dilute the lubricating oil. When the compressor starts, this refrigerant-oil mixture can cause slugging, bearing wear, and catastrophic compressor failure. The HTR2444 keeps the oil warm and refrigerant-free, ensuring smooth, reliable startups and extended compressor life.

Installation Notes
Always de-energize the system before servicing. Allow the crankcase heater adequate warm-up time (typically 4–8 hours) before starting the compressor after an extended shutdown, especially in cold weather. Consult the applicable Trane service documentation for unit-specific installation procedures and torque specifications.
