Trane HTR4907 Crankcase Heater
The Trane HTR4907 Crankcase Heater is a critical component for maintaining compressor reliability in commercial and residential HVAC systems. Designed as an insertion type heating element, this 230-volt, 40-watt unit effectively migrates refrigerant out of the compressor oil during the off-cycle. This prevents flooded starts and ensures proper lubrication of the scroll or reciprocating internal components upon startup. With a precise 1/4" diameter and a 4 1/4" insertion length, the HTR4907 provides direct thermal transfer within the compressor housing, outperforming external belly band heaters in extreme cold conditions.
For service technicians, the 64" lead length offers significant vertical and horizontal reach for clean wire routing to the contactor or control board. As a genuine Trane OEM part, it guarantees exact fitment for compatible Trane and American Standard heat pumps and air conditioning units. Utilizing a stainless steel sheath for corrosion resistance, this 40W crankcase heater is built to withstand the high-temperature environment of an active compressor sump while delivering consistent wattage to protect the refrigeration system from premature mechanical failure.
Key Benefits- 230-Volt Operation: Optimized for standard residential and commercial power supplies to ensure consistent 40W heat output.
- Direct Insertion Design: The 1/4" diameter probe installs directly into the compressor well for maximum heat transfer efficiency compared to surface-mount heaters.
- Extended 64" Leads: Provides ample length for secure routing through high-voltage compartments and wiring harnesses.
- Refrigerant Migration Protection: Minimizes oil dilution and "slugging" to protect the compressor’s mechanical integrity during cold weather starts.
- OEM Compatibility: Precision engineered for seamless integration with specialized Trane and American Standard compressor wells.
Is the HTR4907 compatible with other HVAC brands?
While and the electrical specifications are standard, the 1/4" diameter and 4 1/4" insertion length are specifically engineered for the internal heater wells found in Trane and American Standard compressors. Always verify the compressor model’s internal well dimensions before attempting to use this in a non-OEM application.
How do I verify the heater is functioning correctly?
A veteran tech should check for continuity across the leads when the heater is disconnected. With the heater energized during the off-cycle, use an ammeter or a non-contact thermometer to confirm the unit is drawing the rated wattage and maintaining the sump temperature above the ambient saturation point.
Does this heater run while the compressor is active?
No. In most a standard HVAC wiring configuration, the crankcase heater is wired to be energized only when the compressor contactor is open. This ensures the oil stays warm during the off-cycle and avoids unnecessary energy consumption during operation.
