The Goodman 10135604 Relay is a genuine OEM switching relay for ASZ130241AC ASZ13-series 2-ton heat pumps. The relay takes a low-voltage command from the defrost/control board and switches a higher-current load — such as the reversing valve, auxiliary heat, or fan circuit — allowing a small board signal to control a large electrical load safely. Symptoms of a failed relay include chattering, welded-closed contacts that leave a load stuck on, or an open coil that prevents a stage from energizing.
This genuine Goodman OEM relay matches the exact coil voltage, contact rating, and terminal layout the ASZ13 board expects. Generic relays with mismatched coil voltage or contact ampacity can fail early or overload the board. OEM ensures correct switching and drop-in terminals.
Easy (2 of 5). Cut power at the disconnect, photograph the wiring, transfer the leads one at a time to the new relay, and mount. Typically 15–20 minutes with a nut driver and needle-nose pliers. Verify power is off before servicing.
