The relay handles control-circuit switching — energizing components on command from the control board — and is a frequent wear item, since contacts erode over thousands of switching cycles. A failing relay shows up as intermittent operation, chatter, or a component that won't energize.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10135604\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e WGHP4448AAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Electromechanical switching relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil:\u003c\/strong\u003e 24V control circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Packaged heat pump control switching\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM relay matches the original coil voltage, contact rating, and terminal layout for true plug-in replacement.
