Daikin-McQuay PCBHR105S PCB Control Board for Communicating Heat Pump Condensing Units

The Daikin-McQuay PCBHR105S is a genuine OEM printed circuit board (PCB) control board engineered for communicating heat pump condensing units across the Goodman, Amana, Daikin, and McQuay brand families — all manufactured by Daikin Comfort Technologies. This direct-fit replacement board restores proper system operation in compatible DSZC, ASZC, GSZC, and DZ/DZT-series outdoor condensing units.

The PCBHR105S serves as the central controller for the outdoor unit, managing compressor sequencing, fan motor operation, and two-way communication with indoor air handlers and thermostats. Operating on a 24V control circuit, it coordinates heating and cooling cycles to maintain efficient, reliable system performance.
