What Is the DA94-04603G Samsung Refrigerator Main Control Board Replacement?
The DA94-04603G is the main control board for Samsung French-door refrigerators, mounted inside the electronics housing near the rear/top machine compartment. 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.
This 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.
What Does the DA94-04603G Fix on a Samsung Refrigerator?
If your refrigerator is showing any of these problems, a failing control board is a likely cause:
- Refrigerator not cooling
- Display panel showing error codes
- Compressor not running or cycling on and off erratically
- Fridge and freezer temperatures don't match what you set
- Defrost cycle not kicking in when it should
- Control panel or display unresponsive or blank
These 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.
How Do I Know If This Is the Right Board for My Refrigerator?
Check 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.
Other part numbers used for this board: AP6974660, EAP12739670, PS12739670, PD00073569, OEM20923989, ERP12739670, SAM-DA94-04603G. Retailers and parts catalogs list the same board under these numbers.

Board Type and Function
The main control board is the brain of the refrigerator's cooling system. It reads input from the temperature sensors and tells the compressor and fans when to run, keeping the fridge and freezer at their set points. It also manages the defrost cycle, triggering it on schedule so ice doesn't build up on the evaporator coils. When this board fails, the whole cooling system loses coordination, which shows up as inconsistent temperatures, error codes, or a unit that won't cool at all.
Common Samsung Refrigerator Error Codes
If your Samsung refrigerator is displaying an error code, the table below describes what it typically indicates. These are general Samsung codes and can vary by your exact model, so use this as a general guide. Codes marked ★ are most directly associated with main control board failure. Always confirm the exact meaning in your model's owner's manual or service guide before ordering any part.

How to Install a Samsung Refrigerator Main Control Board
Start by unplugging the refrigerator or shutting off power at the breaker. 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.
Shipping
Every board is physically in stock - no backorders, no drop shipping. Orders placed before 4:00 PM EST ship the same business day. Tracking provided on every order.
Warranty
Backed by a 1-year warranty from Appliance Pro USA (registration required - the card is in the box). 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.
Returns
Returns 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. Restocking and retesting fees may apply to opened or installed boards - these fees are waived for exchanges, though reshipping costs and any price difference between products will apply. 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.
Important Installation Notes
This 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.
Some 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.
Installation 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.
Even if you end up calling a pro, knowing your part number and symptoms before the tech arrives usually shortens the visit and the bill.
