The Goodman 10135604 Relay is the genuine OEM switching relay used in the ASH130361AD 3-ton, 13 SEER heat pump. This electromechanical relay opens and closes a high-current circuit in response to a low-voltage control signal, allowing the board or thermostat to safely energize a load such as the outdoor fan or an auxiliary function.
Relays wear out from millions of switching cycles; symptoms of failure include a component that won't energize, chattering contacts, or intermittent operation on cooling or heating calls. Replacing with the factory relay restores the correct coil voltage rating and contact ampacity.
The OEM 10135604 matches Goodman's exact coil voltage, contact rating, and terminal spacing, so it drops onto the existing spade connectors without adapters. Generic relays may differ in pinout or contact rating, risking a loose fit or premature failure. For dependable switching we recommend the OEM part.
Easy to Moderate — about 15–20 minutes. Shut off power at the breaker, note or photograph the wiring, transfer each spade terminal to the new relay, and secure it in the original mounting location. Basic electrical care applies; when in doubt, use a licensed technician.
