Trane HTR2444 150W Crankcase Heater 120V

The Trane HTR2444 is a 120V, 150W crankcase heater for Trane HVAC systems. It is a part of your compressor unit’s crankcase. Picture a small heating pad wrapped around the oil sump. Its major function is to keep the oil warm when the weather is cold. The crankcase heater reduces excessive oil viscosity, especially during the first cold snaps of the season, thus allowing smooth compressor startup and operation. It protects your compressor from the damage caused by thick, sluggish oil, and helps keep your Trane HVAC system running the way it should.
