The Goodman 10135604 is a genuine OEM relay for the DCC300XXX3BXXXAB air conditioner and compatible Goodman/Amana packaged units. This control relay switches power to a load—such as the compressor contactor circuit, fan, or an accessory—in response to the unit's control signal, providing reliable, correctly-rated switching within the factory control scheme.
This genuine Goodman relay matches the coil voltage, contact rating, and terminal layout your system expects, so it drops into the existing harness without rewiring. Generic relays may differ in contact ratings or pin configuration, risking premature failure or miswiring. OEM is the safe, plug-in-ready choice.
Easy. No refrigerant work involved—disconnect power, photograph the existing wiring, transfer the leads to the new relay one at a time, and remount. A confident DIYer can handle this with the wiring diagram; otherwise contact a qualified technician.
