Goodman 10135604 Relay

The Goodman 10135604 is a genuine OEM relay for the ASZ130421AB 13 SEER heat pump. This relay handles the electromechanical switching that coordinates control and defrost functions in the outdoor unit, energizing loads on command from the control board. When a relay's contacts pit, weld, or fail to close, you'll see symptoms like a unit that won't start, won't reverse into defrost, or short-cycles — replacing the relay restores clean, positive switching.

OEM Part Number: 10135604
Fits Model: ASZ130421AB (3.5-ton / 42,000 BTU heat pump)
Brand: Goodman
Type: Electromechanical control relay
Terminals: Quick-connect spade fittings for direct plug-in service

OEM vs. Generic

The OEM 10135604 is matched to the correct coil voltage, contact rating, and terminal layout for the ASZ13 control circuit. Substituting a generic relay with a different pinout or contact rating risks miswiring, chatter, or contact failure under the unit's inductive load. The genuine part drops in and is rated for the actual switching duty.

Installation Difficulty: Easy

Disconnect power at the outdoor disconnect and main breaker before servicing. Note or photograph the wire positions, unplug the spade connectors from the old relay, unclip it from the bracket, mount the new 10135604, and transfer each lead to the matching terminal. A quick 15-minute repair for anyone comfortable matching labeled terminals; otherwise call a licensed technician.

Restore reliable switching to your heat pump with the genuine Goodman 10135604 relay.
