The Goodman 10135604 is a genuine OEM defrost control relay engineered for the ASZ130301AC 13 SEER, 2.5-ton (30,000 BTU) heat pump condenser and compatible Goodman/Amana split-system heat pumps. This relay switches the reversing valve and defrost circuit on a 24V control signal, ensuring reliable heating-mode operation and proper defrost cycling during cold-weather conditions. A failed relay commonly presents as no defrost, a stuck reversing valve, or intermittent heat-pump operation.
This is the factory OEM Goodman relay — an exact-match component built to the original electrical and mechanical spec, guaranteeing correct coil resistance and contact rating. Generic aftermarket relays may cost less but risk mismatched contact timing, premature contact wear, and voided equipment warranties. For a control component that governs defrost, OEM is the safe choice.
Easy — DIY-friendly (2/5). Requires disconnecting power at the breaker, unplugging the old relay, and seating the replacement. Label wires before removal. If your unit shows control-board faults, have an HVAC technician verify the diagnosis first.
Always disconnect power before servicing HVAC equipment.
