Daikin-McQuay 112056401 Crankcase Heater

Daikin-McQuay 112056401 Crankcase Heater

The Daikin-McQuay 112056401 Crankcase Heater is a critical OEM replacement part designed to maintain optimal compressor oil temperature during the off-cycle. Engineered for heavy-duty commercial and residential HVAC applications, this 120V 90 Watts Crankcase Heater provides the necessary thermal energy to prevent refrigerant migration into the compressor shell. By keeping the lubricant above the refrigerant’s saturation point, it eliminates the risk of flooded starts and oil dilution, which are leading causes of mechanical failure in low-ambient conditions.

This HVAC compressor heater features a robust heating element that ensures consistent heat transfer to the crankcase. Its technical specifications—operating at 120 volts with a 90-watt power rating—ensure compatibility with specific Daikin and McQuay condensing units requiring precise thermal management. For technicians, installing this genuine crankcase heating element is standard preventative maintenance to ensure the compressor lubricant viscosity remains within manufacturer specifications, preventing liquid slugging and protecting internal scrolls or reciprocating components during startup.

Key Benefits
  • Prevents Refrigerant Migration: Stops liquid refrigerant from condensing in the oil during idle periods, ensuring a dry startup.
  • Eliminates Flooded Starts: Reduces the risk of oil foaming and subsequent bearing wear or mechanical damage.
  • Optimized 120V Performance: Specifically rated at 90W to provide the correct watt-density for targeted thermal protection without overheating.
  • Daikin-McQuay OEM Compatibility: Guaranteed fit and performance for specific 112056401 part number applications.
  • Enhanced System Reliability: Maintains proper oil temperature in cold environments, extending the operational life of the compressor.
Common Questions

How do I verify if my crankcase heater has failed?
Technicians should check for continuity across the heater leads using a multimeter. If the circuit is open or if there is a short to the ground, the heater must be replaced to prevent compressor damage during the next cold start.

When should the 112056401 heater be energized?
This heater is typically wired to be energized whenever the compressor is in the "off" cycle. It should not be powered while the compressor is running, as the heat of compression maintains the oil temperature during operation.

What happens if a 120V heater is used on a 240V circuit?
Applying 240V to a 120V-rated heater will cause an immediate over-wattage condition, leading to rapid element burnout and potential safety hazards. Always confirm the supply voltage matches the 120V rating of this part.
