The Goodman 10135604 Relay is a genuine OEM electrical control component for the ASZ130301AA 2.5-ton heat pump and compatible Goodman/Amana 13-SEER condensing units. This relay handles switching in the compressor start/control circuit, energizing and de-energizing loads on command from the low-voltage control signal. A failed relay is a common cause of a compressor that hums but won't start, or an outdoor unit that won't respond to a call for cooling or heating.
The genuine 10135604 is matched to the coil voltage, contact rating, and terminal layout of the ASZ130301AA, so it drops in without rewiring. Generic relays may require adapter wiring and can carry different pickup/dropout voltages, risking nuisance faults or contact chatter. For dependable switching, the OEM relay is the safe choice.
Intermediate. With power disconnected at the breaker/disconnect, photograph and transfer the wiring one terminal at a time, then mount the new relay. No refrigerant work required. A multimeter is recommended to confirm the fault before replacing.
Genuine Goodman quality for reliable heat pump operation.
