The Trane HTR71631 is a factory-specified crankcase heater engineered to protect compressor reliability in commercial and residential HVAC systems. By maintaining the compressor crankcase at an elevated temperature during off-cycles, this heater prevents refrigerant from migrating into and mixing with the compressor oil — a leading cause of compressor damage and premature failure.
Why Crankcase Heaters Matter
During system shutdown, refrigerant can migrate to the compressor sump and dissolve into the lubricating oil. At startup, this refrigerant-oil mixture can cause slugging, oil foaming, and bearing wear. Installing or replacing a crankcase heater is a low-cost, high-impact measure that extends compressor life and reduces costly service calls.
