The Goodman 10135604 Relay is a genuine OEM electromechanical relay used in the ASZ130421AA heat pump to switch control-circuit loads on and off in response to the thermostat and control board. A properly functioning relay is essential for reliable compressor and fan-motor operation.

Specifications

Part Number: 10135604
Type: Control / switching relay
Contact Rating: Rated for HVAC control loads (see unit wiring diagram)
Coil Voltage: 24V control circuit
Fits Model: ASZ130421AA (3.5-ton, 13 SEER heat pump)

OEM vs. Generic

The genuine OEM 10135604 matches the original coil voltage, contact rating, and terminal layout exactly, so it drops into the factory harness without adapters or rewiring. Generic relays may carry different contact ratings or pin arrangements, risking chatter, welded contacts, or intermittent operation. For a component that cycles thousands of times per season, the reliability of the OEM part pays off.

Installation Difficulty: Moderate

Shut off power at the disconnect, photograph the wiring for reference, transfer the leads one at a time to the matching terminals on the new relay, and secure it to the original mount. Expect 20–30 minutes. Because it involves control wiring, this job is best handled by an HVAC technician or a confident, careful DIYer who verifies each connection against the wiring diagram.

Restore dependable switching to your Goodman heat pump with this genuine OEM relay.
