Carrier HR54AA105 Switch
The Carrier HR54AA105 Fan Cycling Switch is a critical high-pressure control designed for precise condenser fan motor management in commercial HVACR systems. This SPST (Single Pole Single Throw) switch ensures optimal head pressure by cycling the fan based on refrigerant system requirements, commonly utilized in Carrier, Bryant, and Payne rooftop units and chillers. Engineered for durability, the HR54AA105 features a standard 1/4-inch SAE female flare nut with a Schrader valve depressor, allowing for direct mounting on the high-side service port without refrigerant loss. Designed to handle R-410A and R-22 pressures, it provides reliable condenser pressure control in low ambient conditions. This OEM replacement part replaces obsolete fan cycle controls, restoring factory-specified performance. Its heavy-duty electrical contacts are rated for high-cycle applications, ensuring the HVAC pressure switch maintains consistent set-points for low ambient cooling operation.
Item is Non Cancelable / Non Returnable
Key Benefits- OEM Precision: Genuine Carrier replacement part ensures exact electrical ratings and pressure set-points for system safety.
- Simplified Installation: Integrated flare fitting allows for quick attachment to the liquid line or discharge header.
- Reliable Fan Cycling: Prevents evaporator freeze-ups by maintaining head pressure during low-load or cold weather operation.
- Robust Construction: Hermetically sealed design protects internal components from moisture and vibration common in outdoor condensing units.
What are the cut-in and cut-out pressures for the HR54AA105?
This switch is calibrated for high-pressure systems, typically featuring a 400 PSI cut-in and a 290 PSI cut-out, though technicians should verify specific Carrier switch specifications against the unit nameplate.
Is this switch compatible with R-410A refrigerant?
Yes, the Carrier HR54AA105 is rated for the higher operating pressures associated with R-410A systems and is backwards compatible with R-22 applications.
Can I install this switch without recovering the refrigerant?
If the system port is equipped with a Schrader core, the integrated depressor pin allows for installation without a full system pump-down.
