The genuine Goodman 10135604 Relay is a factory replacement switching relay for the Goodman WGHP4660AAF air conditioner. This relay handles the high-current make-and-break that energizes the compressor or fan circuit on command from the thermostat and control board. Burned, pitted, or chattering relay contacts cause intermittent cooling, a unit that won't start on a call, or a buzzing that never closes the circuit — all classic symptoms that a tired relay needs replacement.
The OEM Goodman 10135604 matches the original coil voltage, contact rating, and terminal footprint exactly, so it drops into the WGHP4660AAF without rewiring. Generic substitutes may carry a lower contact rating that welds shut under the compressor's inrush current, risking a no-cool callback or a damaged control board. For a circuit that switches your compressor, OEM reliability matters.
Moderate (3 of 5) — Power must be off at the disconnect. The relay leads should be photographed and transferred one at a time to avoid miswiring. Best handled by a technician comfortable reading the unit's wiring diagram.
