Carrier HT32CH220 Crankcase Heater

The Carrier HT32CH220 Crankcase Heater is a critical OEM replacement part designed for technicians who prioritize compressor longevity and cold-start reliability. This belt-type heater (also known as a belly band) features a 6-7" diameter adjustable fit and comes equipped with 60-inch leads for streamlined integration into the control box. Operating at 240V with a 40W output, it provides the precise thermal energy required to maintain oil temperature above the refrigerant saturation point during the off-cycle.

For any commercial HVAC service or residential compressor repair, preventing refrigerant migration is non-negotiable. This heater ensures that refrigerant stays in the condenser and evaporator, preventing oil dilution and subsequent bearing failure or liquid slugging upon startup. Designed to fit a wide range of Carrier, Bryant, and Payne scroll and reciprocating compressors, the HT32CH220 is the professional choice for maintaining HVAC system efficiency in cold climates or long-line applications. Its robust construction resists environmental stressors, addressing common failure points like brittle wiring or terminal shorts often seen in universal aftermarket alternatives.

• Universal Compatibility: Adjustable strap fits 6-inch to 7-inch compressor shells used across multiple Carrier HVAC models.
• Enhanced Protection: Prevents flooded starts by keeping compressor oil warm and at the correct viscosity.
• Simplified Installation: 60-inch wire leads provide ample length for routing to the contactor without the need for additional splicing.
• OEM Reliability: Built to exact technical specifications, ensuring the wattage-to-displacement ratio is optimized for the motor housing.

• How is the HT32CH220 wired? It is typically wired across the open contacts of the compressor contactor so it energizes when the unit is in the off-cycle.
• Does this heater require a thermostat? While many Carrier units use an ambient temperature switch to control the circuit, this heater can be integrated into existing safety controls to prevent operation above 66°F.
• What prevents it from overheating the compressor? The 40W self-regulating properties and physical placement (2 inches above the mounting plate) allow for consistent heat transfer without damaging shell welds.
