The Goodman 10135604 Relay is a genuine OEM control-circuit relay engineered for DCC300 series commercial packaged air conditioners, including the DCC300XXX7BXXXAB. This relay switches a load circuit in response to a low-voltage control signal, coordinating components such as fans, compressor contactors, or auxiliary controls so the unit sequences correctly during each operating cycle.
This genuine Goodman OEM relay guarantees the correct coil voltage, contact rating, and terminal configuration for a plug-and-play fit in your DCC300 unit. Generic relays can differ in pinout or contact capacity, risking miswiring or premature failure. For reliable sequencing, OEM is the safe choice.
Easy to Moderate — A straightforward electrical replacement: disconnect power, transfer wiring or unplug/replug the relay, and confirm against the wiring diagram. No refrigerant handling required.
