The Goodman 10135604 is a genuine OEM control relay engineered for DCC072XXX7VXXXAA commercial package air conditioners. This relay switches the unit's fan and control circuits in response to the 24-volt thermostat and control-board signals, ensuring the blower and contactor energize reliably on every call for cooling. A failing relay commonly shows up as a unit that won't start, intermittent fan operation, or chattering at the control board.
This is the factory OEM Goodman relay — built to the exact coil resistance, contact rating, and terminal layout the unit was designed around, so it drops in without rewiring. Aftermarket generic relays may save a few dollars but can vary in contact rating and footprint, leading to nuisance failures and warranty headaches. For a control component this critical, OEM is the safe choice.
Easy (2/5). A qualified technician can swap this relay in 10–15 minutes. Disconnect power, photograph the wiring, transfer leads one at a time, and verify operation. Always confirm power is off and follow Goodman service procedures.
