This board manages the indoor blower motor's timed fan-on and fan-off delays, improving comfort and efficiency by allowing the coil to fully energize before airflow starts and by purging residual conditioned air at the end of a cycle. A failed board commonly shows up as a blower that won't start, won't stop, or short-cycles.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Fan\/blower time-delay relay control board\u003c\/li\u003e\n\u003cli\u003eOEM part number: PCBFM103S\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003eFits: GPC1342H21A package air conditioner\u003c\/li\u003e\n\u003cli\u003eFunction: Timed blower on\/off delay control\u003c\/li\u003e\n\u003cli\u003eOnboard relay for indoor blower motor switching\u003c\/li\u003e\n\u003cli\u003eDirect plug-in OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM PCBFM103S arrives pre-programmed with Goodman's exact delay timing and uses connectors that match the factory wiring harness for a true plug-and-play swap.
