Trane HTR15185 Crankcase Heater

The Trane HTR15185 Crankcase Heater is a critical component for maintaining compressor reliability, specifically designed to prevent refrigerant migration and oil dilution during the off-cycle. This belt type crankcase heater operates at 200 volts and provides a constant 160 watts of heat, ensuring the lubricant remains above the refrigerant saturation point. Engineered as the direct replacement for HTR6623, it is purpose-built for Trane HVAC units and condensing systems. The heater features a wrap-around design with a 12 to 12.5-inch diameter and 22-inch leads, allowing for a secure, snug fit to the compressor housing. This OEM crankcase heater is essential for avoiding flooded starts, which often lead to liquid slugging and mechanical failure. By keeping the sump warm, this compressor heater belt facilitates smooth lubrication at startup, protecting the internal bearings and extending the service life of the Trane replacement part in demanding commercial or residential applications.

• Universal Compatibility: Serves as the factory-authorized direct replacement for HTR6623, ensuring no-hassle installation and precise electrical matching.
• Optimized Heat Transfer: The belt type construction maximizes surface contact with the compressor shell for efficient thermal conductivity.
• Prevents Flooded Starts: Maintains oil temperature to drive off liquid refrigerant, eliminating the primary cause of compressor damage in cold ambient conditions.
• Durable Technical Profile: Rated at 200V / 160W with 22-inch leads, providing the necessary reach and power for large-diameter compressor housings.

Is the HTR15185 compatible with 208V systems?
Yes. While rated at 200V, this heater is commonly utilized in 208V applications typical of Trane commercial and residential equipment, provided the wattage remains within the compressor manufacturer's tolerances.

What is the primary sign of a failed crankcase heater?
Technicians should look for tripped breakers, blown fuses, or high oil viscosity during cold starts. A functioning Trane HTR15185 should be warm to the touch when the compressor is in the off-cycle.

Can this belt fit a range of compressor sizes?
The heater is specifically designed for compressors with a 12 to 12.5-inch diameter. Attempting to fit it on smaller or larger housings can result in poor heat transfer or physical damage to the heater element.
