The Goodman 10135604 Relay is a genuine OEM electromechanical relay for the Goodman WGHP4448AAE packaged heat pump. The relay handles control-circuit switching — energizing components on command from the control board — and is a frequent wear item, since contacts erode over thousands of switching cycles. A failing relay shows up as intermittent operation, chatter, or a component that won't energize.

OEM vs. Generic

The OEM relay matches the original coil voltage, contact rating, and terminal layout for true plug-in replacement. Generic relays may carry different contact ratings or pin spacing, requiring adapters and risking premature failure under HVAC inrush loads. OEM ensures a drop-in, spec-correct fit.

Install Difficulty

Moderate. Disconnect power, photograph the wiring, transfer leads one at a time to the new relay, and confirm seating. Basic electrical comfort required; otherwise schedule a technician.
