The Goodman 10135604 Relay is a genuine OEM switching component for the Goodman DBC3003VDDCAA air conditioner and compatible condensing units. The relay energizes and de-energizes a load — such as the compressor contactor coil, blower, or an accessory circuit — on command from the control board or thermostat. Pitted contacts, a weak coil, or a chattering relay can cause a no-start, intermittent operation, or a component that won't shut off; replacing the relay restores clean, dependable switching.
This genuine Goodman OEM relay matches the factory coil voltage, contact rating, and terminal pinout, ensuring a true plug-in fit and rated contact life. Generic equivalents may list comparable specs but often vary in footprint or pinout, inviting miswiring and early failure. For reliable control switching, OEM is the safe choice.
Difficulty: Easy to Moderate. Shut off power at the breaker, open the control box, and photograph the existing wiring. Transfer the connections one at a time to the new relay, or unplug and re-seat if it is a plug-in style. Most replacements take 20–30 minutes. When in doubt about the wiring, consult a licensed HVAC technician.
