Description
The Trane HTR1566 is a genuine OEM crankcase heater engineered to protect compressor integrity in HVAC systems. Operating at a dual-voltage range of 110–220V and rated at 140 watts, this heater keeps compressor oil warm during off-cycles, preventing refrigerant migration into the crankcase — a leading cause of compressor damage and premature failure.
By maintaining a consistent temperature around the compressor housing, the HTR1566 ensures that lubricating oil remains at the proper viscosity for safe, reliable startup. This is especially critical in low-ambient or cold-weather installations where refrigerant tends to condense and mix with compressor oil during extended off periods.

Why Crankcase Heaters Matter
Crankcase heaters are a critical compressor protection component. Without one, refrigerant can migrate into the compressor sump during the off-cycle, diluting the oil and causing liquid slugging on startup. The Trane HTR1566 eliminates this risk, safeguarding your compressor investment and keeping systems running efficiently season after season.
