The Goodman 10135604 is a genuine OEM control relay engineered for the DCC0720207VHDXAA packaged air conditioner and other compatible Goodman/Amana commercial units. This relay switches low-voltage control signals to high-voltage components, coordinating compressor and fan operation during each cooling cycle. A failing relay commonly shows up as a unit that won't start, chatters, or trips on a call for cooling.
The OEM relay is the exact factory part — guaranteed coil voltage, contact rating, and terminal layout for a true plug-in replacement with no rewiring. A generic relay can save money but may differ in mounting footprint or contact life. For commercial rooftop reliability, the OEM part is the safe choice.
Easy (2/5) — Disconnect power, photograph the wiring, swap terminals one at a time, and re-test. Most techs complete this in under 15 minutes. Always cut power at the disconnect before servicing.
