What Is the DA94-05319C Samsung Refrigerator Main Control Board Replacement?
The DA94-05319C is a genuine Samsung replacement control board for refrigerators, mounted in the rear of the fridge compartment or behind a rear access panel depending on the model line. It manages compressor cycling, defrost timing, fan operation, and reads the temperature sensors that keep both the fresh food and freezer sections at the right temperature. FailSafe Certified and backed by a 1-year warranty from Appliance Pro USA.
What Does the DA94-05319C Fix on a Samsung Refrigerator?
This board is commonly the cause when you see any of the following:
- Refrigerator not cooling at all
- Freezer works but fresh food section is warm (or vice versa)
- Display panel is blank or unresponsive
- Refrigerator runs constantly and won't cycle off
- Compressor or fans fail to start
- Intermittent loss of power to lights, ice maker, or dispenser
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 you order, pull the rear or interior access panel and find the sticker on your existing board. If it reads DA94-05319C, you've got a match - this is the number to go by, not the model number stamped on the refrigerator itself. Your Samsung refrigerator part number is on the sticker on the original board - look for the DA41-, DA92-, or DA94- prefix.

Board Type and Function
The main control board is the brain of the refrigerator's cooling system. It takes readings from the temperature sensors and decides when to run the compressor and fans, and when to trigger a defrost cycle. It also handles power distribution to smaller components like the ice maker, dispenser, and interior lights. When this board fails or starts misbehaving, the whole cooling system loses its coordination, even if individual parts like the compressor or fans are still good.

How to Install a Samsung Refrigerator Main Control Board
Start by unplugging the refrigerator or shutting off power at the breaker. Remove the rear or interior access panel to get to the board, and before you touch anything, label or photograph each wiring harness connector so you know exactly where it goes back. Disconnect the harnesses, pull the mounting screws, and swap in the new board, using a grounding strap or touching a grounded metal surface first to protect it from static. Most people get this done in under 30 minutes with basic hand tools. Once it's back together and powered up, give the refrigerator a few hours to reach temperature before you judge whether the repair worked.
