Copeland 918-0043-00 Crankcase Heater

Copeland 918-0043-00 Crankcase Heater

The Copeland 918-0043-00 Crankcase Heater is a critical 240V 70W belt type heater designed to maintain optimal oil temperature and prevent refrigerant migration during compressor off-cycles. As a veteran technician knows, cold-start liquid slugging is a primary cause of premature Copeland Scroll compressor failure. This wrap-around heater provides an essential 70-watt thermal barrier, ensuring that refrigerant stays in the evaporator rather than diluting the lubricant in the crankcase. Engineered for professional HVACR maintenance, the 918-0043-00 features a rugged belt-style construction with a 48-inch lead length, facilitating a secure fit around the compressor base. It is compatible with a wide range of models, including the ZB21KCE-TF5-940 and various ZB, ZR, and ZP series scrolls. By keeping the oil viscosity low in low-ambient conditions, this OEM Copeland part ensures immediate oil pressure upon startup, protecting the internal bearings and extending the service life of the refrigeration system without the complexity of a pump-down cycle.

  • Refrigerant Migration Protection: Effectively prevents liquid refrigerant from mixing with compressor oil during idle periods.
  • High-Efficiency Thermal Transfer: Delivering a consistent 70 Watts of heat to keep oil fluid in low-ambient environments.
  • Universal Compatibility: Designed specifically for Copeland Scroll compressors, fitting models from the ZB, ZF, and ZR families.
  • Durable Belt Design: Features a 48-inch cable length and heavy-duty wrap-around tensioning for reliable surface contact.
  • Easy Drop-in Installation: Standard 240 Volts operation allows for seamless integration into existing control circuits.

Common Questions

How do I confirm if my crankcase heater has failed?
Technicians should check for continuity across the heater leads using a multimeter. If the circuit is open or you observe a tripped breaker during the off-cycle, the crankcase heater likely requires replacement to prevent compressor damage.

Where exactly should this heater be positioned on the compressor?
For maximum heat transfer, the belt type heater must be installed around the lower portion of the compressor shell, typically about two inches above the mounting plate, ensuring it is below the oil level but not interfering with the terminal box.

Does this heater run while the compressor is operating?
No. In a standard HVACR wiring configuration, the heater is wired across the normally closed auxiliary contacts of the contactor so that it only energizes when the compressor is off.
