What Is the DA92-04603E Samsung Refrigerator Main Control Board Replacement?
The DA92-04603E is the genuine OEM main control board for Samsung bottom-mount French door refrigerators. It's mounted behind the rear access panel or in the machine compartment at the back of the unit, wired directly into the compressor, fans, and display harnesses, and it's the replacement control board that governs cooling cycles, temperature regulation, and defrost timing. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
What Does the DA92-04603E Fix on a Samsung Refrigerator?
This board is usually the fix when you're seeing one or more of the following:
- Refrigerator has stopped cooling
- Display panel is blank or completely dead
- Buttons on the control panel don't respond when pressed
- Fridge or freezer temperature keeps drifting or won't hold steady
- Error codes showing up on the display
- No power at all to the refrigerator
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?
Before ordering, pull the rear access panel and check the sticker on your existing board against the number stamped or printed on it. DA92-04603E or AP6883413 printed on that white or silver label both point to this same board, so match what's on your unit rather than relying on the fridge's model number alone. Your Samsung refrigerator part number is on the sticker on the original board - look for the DA41-, DA92-, or DA94- prefix.
Not sure? Send us a photo of your board and its sticker before you order and we'll verify it for free - same business day.
Compatible Refrigerator Models
This board is ordered by part number, not by appliance model. Send us your full model number and a photo of your board's sticker and we will confirm fitment before you buy - same business day.
Also reported to fit: RF28R7201DT, RF28R7201SG, RF28R7201SR, RF28R7201SR/AA. This is general reference material - confirm by the part number on your board's sticker before ordering.
This model list is for reference only. Samsung may change boards between production runs, so two appliances with the same model number can use different boards. Always order by the part number printed on your original board - it is the only identifier that decides.

Board Type and Function
This is the main power and control board for the refrigerator, and it acts as the brain of the whole system. It manages the compressor cycles, runs the evaporator and condenser fans, times out the defrost cycle, and keeps the fridge and freezer at the temperatures you set. It also talks to the display panel, so anything from a dead screen to unresponsive buttons often traces straight back to this board. When it fails or degrades, cooling performance and temperature control go with it.

How to Install a Samsung Refrigerator Main Control Board
Unplug the refrigerator and shut off the water supply before you start, and move any perishable food out since power will be down for the swap. Remove the rear access panel screws to expose the board, and take a photo of the wiring harnesses before you pull any of them loose. Ground yourself or wear an anti-static strap while handling the new board, since these PCBs are sensitive to static. Swap the board, plug every harness back into its original spot using your photo as a guide, then reinstall the panel. Most people finish this install in under 30 minutes with basic hand tools. Once you restore power, give the refrigerator a few hours to stabilize before judging 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.
