The Goodman 10135604 Relay is a genuine OEM control relay designed for WGHP4348AAA heat pump systems. This relay switches power to a load — such as the compressor, fan, or defrost circuit — in response to the control board signal. A failed relay results in no-start conditions, chattering contacts, or components that won't energize, so a precise replacement restores reliable system operation.

OEM vs. Generic

The OEM 10135604 is rated for the exact coil voltage, contact amperage, and terminal layout of the WGHP4348AAA control circuit. Generic relays may differ in pinout, coil rating, or contact load capacity, leading to miswiring or premature failure. The OEM relay drops in without adapters and preserves manufacturer reliability.

Installation Difficulty

Easy to Moderate — disconnect power, note wire positions, and swap the relay on its mount. No refrigerant work required. Best performed by a qualified technician for correct lead identification.
