The Goodman 10135604 Relay is a genuine OEM switching relay for the WGHP4648AAE packaged heat pump. It uses a low-voltage control coil to make and break a higher-current load circuit, energizing components such as the fan or accessory loads on command from the control board or thermostat. Chattering, welded, or open relay contacts cause no-start, short-cycling, and erratic operation — symptoms this OEM replacement resolves.

Specifications

OEM Part Number: 10135604
Component: Electromechanical control relay
Compatible Model: WGHP4648AAE
Brand: Goodman
Equipment Type: Packaged Air Conditioner / Heat Pump
Matched coil voltage and contact rating for the original circuit

OEM vs. Generic

The OEM relay carries the exact coil voltage, contact rating, and terminal layout the control circuit was designed around, so it drops in and switches reliably. Substitute relays with mismatched coil voltage or undersized contacts can fail early or fail to pull in. OEM matching avoids nuisance callbacks.

Installation

Difficulty: Moderate. With power off, label and transfer each spade terminal to the matching position on the new relay, then secure it to the bracket. Most techs finish in 20–30 minutes; verify operation with the system in both heating and cooling.
