The Goodman 10135604 Relay is a genuine OEM electrical control component for WGHP4336AAA heat pump systems. The relay uses a low-voltage control signal to switch a higher-current load circuit — energizing components such as the fan motor, heater, or compressor contactor coil. A relay with burned, pitted, or stuck contacts causes intermittent operation, no-start conditions, or components that fail to cycle on command.
The OEM 10135604 matches Goodman's coil voltage, contact rating, and terminal layout exactly, so it drops in without rewiring. Generic relays may carry different coil voltages or contact ratings that overheat under this unit's load. Matching the OEM spec avoids miswiring and nuisance failures.
Difficulty: Intermediate. Disconnect power, photograph the wiring, transfer leads to the matching terminals, and secure the relay. No refrigerant work is involved, but follow lockout/tagout and verify with a meter before re-energizing.
