This relay handles the electromechanical switching that coordinates control and defrost functions in the outdoor unit, energizing loads on command from the control board. When a relay's contacts pit, weld, or fail to close, you'll see symptoms like a unit that won't start, won't reverse into defrost, or short-cycles — replacing the relay restores clean, positive switching.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10135604\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e ASZ130421AB (3.5-ton \/ 42,000 BTU heat pump)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Electromechanical control relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Quick-connect spade fittings for direct plug-in service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 10135604 is matched to the correct coil voltage, contact rating, and terminal layout for the ASZ13 control circuit.
