The Goodman 10135604 relay is the genuine OEM switching relay engineered for the WGHP4318AAA packaged air conditioner. This relay controls the energizing of a downstream load — typically the compressor contactor or fan circuit — and a failed unit shows up as a system that won't start, intermittent cooling, or a contactor that never pulls in. Installing the factory-correct part guarantees the coil voltage, contact rating, and terminal layout match your unit exactly.

OEM Part Number: 10135604
Part Type: Switching / control relay
Fits: Goodman WGHP4318AAA package unit
Brand: Goodman (OEM)
Application: Air conditioner / heat pump control circuit

OEM vs. Generic: A generic relay may carry a similar contact rating, but coil voltage tolerance, terminal spacing, and bracket fit can differ — leading to nuisance chatter or premature failure. This genuine Goodman 10135604 drops in with no rewiring and preserves your equipment warranty coverage.

Install Difficulty: Easy (2/5). A qualified tech can swap this in roughly 15 minutes. Always disconnect power at the breaker, photograph or label the wiring before removal, and confirm the new relay seats fully before restoring power.
