Trane HTR15172 Crankcase Heater

The Trane HTR15172 Crankcase Heater is a direct replacement belly band heater engineered for 460V HVAC systems. Designed with a 90-watt power rating, this belt type heater provides consistent thermal energy to the compressor sumps of 9 to 10.5 ton scroll compressors. It fits a compressor shell diameter of 8 to 11 inches, ensuring a snug, high-contact fit necessary for efficient heat transfer. This critical component prevents refrigerant migration and oil dilution during off-cycles, effectively mitigating the risk of liquid slugging or bearing washout upon startup. With 19-inch lead wires, this OEM heater integrates seamlessly into the compressor contactor circuit, maintaining oil viscosity above the refrigerant saturation point. For commercial technicians, this 460 volt crankcase heater is a standard preventative requirement for protecting Trane and American Standard rooftop units and split systems against catastrophic cold start damage.

• Prevents Refrigerant Migration: Keeps the crankcase temperature higher than the rest of the system to ensure suction line pressure remains stable.
• Protects Compressor Longevity: Eliminates oil foaming and flooded starts that cause premature mechanical failure.
• Precise Fitment: Adjustable belly band design accommodates compressor diameters from 8" to 11" for medium-tonnage commercial units.
• OEM RELIABILITY: Built to Trane factory specifications to ensure correct wattage draw and resistance levels for 460V circuits.

Is the Trane HTR15172 compatible with 208/230V systems?
No, this unit is strictly rated for 460V/480V applications. Using this 90W heater on a lower voltage system will result in inadequate heating and potential compressor damage.

Will this heater fit a 5-ton scroll compressor?
The HTR15172 is optimized for larger 9 to 10.5 ton compressors with an 8-11" diameter. Always measure the compressor shell circumference to confirm the belly band will make firm contact.

How do I test a suspected failed HTR15172?
Perform a continuity check or resistance test with a multimeter while the power is disconnected. A failed crankcase heater often presents as an open circuit or can cause tripped breakers if shorted to the shell.
