Goodman 10135604 Control Relay

The 10135604 is a genuine Goodman control relay engineered as a direct replacement for the WGHP4448AAF packaged heat pump. The relay handles the low-voltage switching that energizes higher-load circuits — typically the fan and auxiliary control functions — translating thermostat and board commands into reliable contact closures. A worn relay with pitted or chattering contacts shows up as intermittent operation, a fan that won't start, or buzzing at the control panel, and is a common, inexpensive failure point.

Component Type: Control / switching relay
Compatible Model: WGHP4448AAF (Goodman packaged heat pump)

OEM vs. Generic

This genuine Goodman relay matches the exact coil voltage, contact rating, and terminal layout called out for the WGHP4448AAF control circuit. Generic relays may carry mismatched coil voltage or contact amperage, risking premature failure or board damage. For dependable switching and clean fitment, OEM is recommended.

Installation Difficulty

Moderate. Replacement requires disconnecting power at the breaker, photographing and transferring the wiring one terminal at a time, and snapping the relay into its bracket. Comfortable for an experienced DIYer who respects electrical safety; otherwise use a licensed technician. Always confirm the part against your unit nameplate before ordering.
