The Goodman 10135604 Relay is the OEM switching relay for the ASH130301A heat pump. It uses a low-voltage control signal to make or break a higher-voltage load circuit — energizing components such as the fan or auxiliary heat on demand. A failed relay shows up as a component that won't start, chatters, or sticks on; a fresh OEM relay restores clean switching.
The OEM relay matches the coil voltage, contact rating, and terminal layout of the original, dropping straight in. Generic relays may differ in pinout or amperage rating and need adapting, risking premature contact wear. OEM keeps the circuit within spec.
Easy (2/5). Disconnect power, note or photograph the terminal positions, transfer the wires one at a time to the identical terminals on the new relay, and snap it into place. About 15–20 minutes for a technician.
Disconnect power at the breaker before servicing. Professional installation recommended.
