It manages temperature regulation, cooling, defrost timing, and the communication between the sensors, compressor, and fans that keep the fridge and freezer running right. This replacement control board comes FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.\u003c\/p\u003e\n\u003cp\u003eThis board ships under several store-specific numbers - AP6974660, EAP12739670, PS12739670, ASM1397461, PD00073569, OEM20923989, ERP12739670, and SAM-DA94-04603G - but they all point to the same DA94-04603G board.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Does the DA94-04603G Fix on a Samsung Refrigerator?\u003c\/h2\u003e\n\u003cp\u003eIf your refrigerator is showing any of these problems, a failing control board is a likely cause:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRefrigerator not cooling\u003c\/li\u003e\n  \u003cli\u003eDisplay panel showing error codes\u003c\/li\u003e\n  \u003cli\u003eCompressor not running or cycling on and off erratically\u003c\/li\u003e\n  \u003cli\u003eFridge and freezer temperatures don't match what you set\u003c\/li\u003e\n  \u003cli\u003eDefrost cycle not kicking in when it should\u003c\/li\u003e\n  \u003cli\u003eControl panel or display unresponsive or blank\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 the board itself, not just your refrigerator's model number, before ordering. Unplug the fridge, pull it away from the wall, and open the rear access panel to find the board. If the sticker reads DA94-04603G or any of its cross-reference numbers, you've got the right part. This board is also catalogued under ASM1397461, PD00073569, OEM20923989, ERP12739670, SAM-DA94-04603G - any of those numbers on your sticker means this is your board. Your Samsung refrigerator part number is on the sticker on the original board - look for the DA41-, DA92-, or DA94- prefix.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOther part numbers used for this board:\u003c\/strong\u003e AP6974660, EAP12739670, PS12739670, PD00073569, OEM20923989, ERP12739670, SAM-DA94-04603G.

Remove the rear access panel to reach the board, then take a photo of the wiring harness before disconnecting the keyed connectors so you know exactly where everything goes back. Since this board carries an EEPROM, ground yourself with a strap before handling it to avoid static damage. Unscrew the old board from its mounting standoffs, set the new one in place, and reconnect each harness connector to its original position. Reinstall the access panel, restore power, and most people finish this install in under 30 minutes with basic hand tools. Give the refrigerator a few hours to run a full cooling cycle before you judge whether the repair worked.\u003c\/p\u003e\n\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eEvery board is physically in stock - no backorders, no drop shipping. Orders placed before 4:00 PM EST ship the same business day.

If the board fails due to a defect within the warranty period, we'll repair or replace it at no charge (shipping fees may apply). Warranty coverage is determined at Appliance Pro USA's discretion. Boards that have been tampered with, or with our verification stickers or holograms removed or damaged, are not eligible for warranty coverage. Damage caused by improper installation, electrical surges, or physical damage is not covered.\u003c\/p\u003e\n\n\u003ch2\u003eReturns\u003c\/h2\u003e\n\u003cp\u003eReturns accepted within 30 days of purchase. Items must be returned in original condition. All returns may be subject to deductions for original and return shipping fees.

Boards returned with physical damage, missing components, missing or damaged hologram stickers, or signs of improper installation may not be eligible for a full refund.\u003c\/p\u003e\n\n\u003ch2\u003eImportant Installation Notes\u003c\/h2\u003e\n\u003cp\u003eThis is not a universal control board - it is a direct replacement for the part number printed on your original board. Boards that look identical can be programmed differently, so always match the number on the sticker.\u003c\/p\u003e\n\u003cp\u003eSome models may require a firmware update after installation; firmware updates and configuration changes should be performed by a qualified technician. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.\u003c\/p\u003e\n\u003cp\u003eInstallation is performed at your own risk. By installing this part yourself you assume all risk of the repair, and Appliance Pro USA is not responsible for damage to your appliance or property, lost or spoiled food, or injury occurring during or after installation. If you are not comfortable working around electrical components, have a qualified technician install this part. If there is ever an issue with the part itself, your remedy is repair, replacement, or refund under our warranty and return policies.\u003c\/p\u003e\n\u003cp\u003eEven if you end up calling a pro, knowing your part number and symptoms before the tech arrives usually shortens the visit and the bill.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eLast Updated: September 2026\u003c\/em\u003e\u003c\/p\u003e","brand":"Appliance Pro USA","offers":[{"title":"Default Title","offer_id":48894881824854,"sku":"DA94-04603G","price":149.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0619\/1339\/9382\/files\/da94-04603g-samsung-refrigerator-control-board-front.jpg?v=1789947477","url":"https:\/\/applianceprousa.com\/products\/samsung-refrigerator-control-board-part-number-da94-04603g","provider":"Appliance Pro USA","version":"1.0","type":"link"}
