The Goodman 10135604 is a genuine OEM control relay for the ASH130301AA heat pump. The relay uses a 24-volt control signal from the thermostat or control board to switch line-voltage loads such as the condenser fan motor or compressor circuit. When a relay's contacts pit, weld, or fail to close, the unit may fail to start, short-cycle, or run continuously.
Installing the correct OEM relay restores clean, positive switching and eliminates the intermittent no-start faults that come from worn or heat-fatigued contacts.
The genuine 10135604 is rated for the exact coil voltage and contact amperage the ASH130301AA requires, with the correct mounting and terminal layout for a drop-in fit. Generic relays may carry different contact ratings or footprints, leading to premature contact failure or wiring errors. The OEM relay is the safe, dependable match.
Moderate — Disconnect power at the breaker, label and transfer the wire connections one at a time to the new relay, and secure it in the original mounting position. Basic multimeter skills help confirm coil and contact operation. If unsure about the wiring, consult a licensed HVAC technician.
