The Goodman 10135604 is a genuine OEM relay designed for the ASH130181AA heat pump. This electromechanical relay handles load-switching duty inside the outdoor unit's control circuit — energizing components on a low-voltage signal from the thermostat and control board. When a relay's contacts pit or weld, you'll see symptoms like a unit that won't energize, chatters, or fails to shut off, making this a frequent service-call replacement.
Aftermarket relays vary widely in contact rating and coil voltage, and a mismatch can cause premature failure or nuisance tripping. The OEM 10135604 is spec'd to Goodman's exact coil voltage, contact rating, and terminal arrangement, so it integrates cleanly with the existing wiring harness. For a control component this central, OEM is the safe choice.
Rating: Easy to Moderate (20–30 minutes). De-energize the unit at the disconnect, label and photograph the relay wiring, unplug or unbolt the old relay, and transfer the leads to matching terminals. No refrigerant handling is required. Verify correct switching operation with a meter before restoring the panel and returning the system to service.
