The Goodman 10135604 Relay is a genuine OEM control relay for the DCC300XXX4VXXXAA packaged air conditioner. The relay switches a load circuit on command from the unit's control logic, energizing or de-energizing components such as the fan, compressor contactor coil, or an auxiliary function. Coil voltage and contact rating are matched to the equipment, so the factory part restores reliable switching without the nuisance faults that come from mismatched substitutes.
The OEM 10135604 guarantees the correct coil voltage, contact rating, and terminal pinout for a clean drop-in. Generic relays may carry different ratings or pin layouts, requiring rewiring and risking premature failure. For dependable switching, OEM is the safe pick.
Easy (2/5). Electrical-only replacement with no refrigerant work. Disconnect power, label and photograph the leads, transfer them to the matching terminals on the new relay, and secure it. Confirm proper operation on restart.
