It mounts inside the control housing, usually behind the interior control panel or toward the back of the cabinet, and it runs the core functions that keep the unit cooling - compressor operation, defrost cycle timing, and power and communication to the display board up front. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.\u003c\/p\u003e\n\u003cp\u003eW10120821 was the original production number, and it has since been consolidated into the service replacement WPW10356039. If the sticker on your old board reads W10120821, W10120821-N, W10118747, or SJ-W10120821, this is still the correct board for your refrigerator.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Does the W10120821 Fix on a Whirlpool Refrigerator?\u003c\/h2\u003e\n\u003cp\u003eIf your refrigerator is showing any of these problems, a failing control board is a common cause:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRefrigerator not cooling\u003c\/li\u003e\n  \u003cli\u003eFreezer not cooling or too warm\u003c\/li\u003e\n  \u003cli\u003eIce buildup on evaporator coils \/ not defrosting\u003c\/li\u003e\n  \u003cli\u003eBlank or unresponsive display panel\u003c\/li\u003e\n  \u003cli\u003eControl panel buttons not working\u003c\/li\u003e\n  \u003cli\u003eCompressor runs constantly or won't start\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese symptoms point to the refrigerator control board as the most likely cause - but appliances are complex systems, and the same symptoms can occasionally stem from a sensor, switch, wiring harness, or motor issue. If a technician has identified the control board, or you've ruled out those components yourself, this board is your fix. When in doubt, contact us before you order - we're happy to walk you through some troubleshooting, and a photo of your board is usually all we need. A diagnosis from a local appliance technician works too.\u003c\/p\u003e\n\n\u003ch2\u003eHow Do I Know If This Is the Right Board for My Refrigerator?\u003c\/h2\u003e\n\u003cp\u003eCheck the sticker on your existing board before ordering, not just the model number on the fridge. Unplug the refrigerator, pull it out, and open the control housing to find the board's white or silver label. W10120821, W10120821-N, W10118747, SJ-W10120821, or the service number WPW10356039 printed on that label all mean this is your board. Your Whirlpool refrigerator part number is on the sticker on the original board - look for the W10 or WPW10 prefix. This listing is for revision C - the sticker should read W10120821 Rev C. A different revision letter can be a different board, so match it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOther part numbers used for this board:\u003c\/strong\u003e WPW10356039, W10120821-N, W10118747, SJ-W10120821.

It also supplies power and communication to the user display board up front, so a failing board can take out the readout along with the cooling.
