The relay handles the low-voltage switching that energizes higher-load circuits — typically the fan and auxiliary control functions — translating thermostat and board commands into reliable contact closures. A worn relay with pitted or chattering contacts shows up as intermittent operation, a fan that won't start, or buzzing at the control panel, and is a common, inexpensive failure point.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10135604\u003c\/li\u003e\n\u003cli\u003eComponent Type: Control \/ switching relay\u003c\/li\u003e\n\u003cli\u003eCompatible Model: WGHP4448AAF (Goodman packaged heat pump)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003eApplication: Low-voltage control switching\u003c\/li\u003e\n\u003cli\u003eMounting: OEM bracket \/ spade-terminal connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine Goodman relay matches the exact coil voltage, contact rating, and terminal layout called out for the WGHP4448AAF control circuit. Generic relays may carry mismatched coil voltage or contact amperage, risking premature failure or board damage.
