How to Replace DA31-00146E Evaporator Fan Motor on Samsung Refrigerator — Step-by-Step

You open your Samsung fridge and notice the milk isn't quite as cold as it should be. The freezer seems fine, but that top section? Warmer than usual. Your compressor runs constantly, working overtime but not getting results. Nine times out of ten, you're looking at a failed evaporator fan motor — specifically part DA31-00146E if you've got a Samsung French door model like the RFG237AARS or RF4289HARS.

The evaporator fan is what circulates cold air from your freezer into the fresh food compartment. When it dies, cold air stays trapped in the freezer while your refrigerator section slowly warms up. It's one of the most common failures on Samsung refrigerators, and fortunately, it's something you can fix yourself in about an hour.

What You Need Before Starting

This repair requires basic hand tools you probably already own:

• Phillips head screwdriver
• 1/4" nut driver or socket wrench
• Flathead screwdriver (for prying clips)
• Work gloves (those evaporator covers have sharp edges)
• Towels (for any frost buildup)

Estimated Time: 45-60 minutes

Difficulty: Moderate — You'll need to remove the freezer back panel, but the wiring is straightforward.

Safety First

Unplug your refrigerator before starting this repair. You'll be working near electrical connections and potentially sharp metal edges inside the freezer compartment. The evaporator coils can have frost buildup that melts during the repair, so have towels ready. If your freezer has significant ice accumulation on the back panel, consider letting it defrost for a few hours first — it'll make removing that back cover much easier.

Step 1: Empty the Freezer and Access the Back Panel

Pull everything out of your freezer and remove all the shelves and drawers. You'll see a large plastic cover on the back wall — this is the evaporator cover that hides the coils and fan. Remove the screws holding this panel in place (usually 4-6 Phillips head screws around the perimeter). Some models have clips at the bottom that need to be gently pried loose with a flathead screwdriver. Be patient here; these clips can be stubborn, especially if there's ice buildup.

Step 2: Locate and Disconnect the Old Fan Motor

With the cover removed, you'll see the evaporator coils and the fan motor mounted in a housing, usually on the left side. The DA31-00146E motor has a wire harness connector — squeeze the locking tab and pull it straight out. Don't yank on the wires themselves. Remove the mounting screws holding the fan motor bracket in place (typically 2-3 screws). The entire fan assembly should lift out.

Step 3: Install the New DA31-00146E Motor

Your new motor comes with the fan blade already attached, which saves you a step. Position it in the same orientation as the old one — the blade should spin freely without hitting anything. Secure it with the mounting screws, making sure it sits flush against the housing. Connect the wire harness until you hear or feel it click into place. Give the blade a gentle spin by hand to confirm nothing's obstructing it.

Step 4: Reassemble the Evaporator Cover

Line up the back panel and snap the bottom clips back into place first, then secure the screws around the perimeter. Don't overtighten — these are going into plastic, and you can crack the housing if you're too aggressive. Make sure all the screw holes line up properly before tightening any of them down.

Step 5: Restore Power and Test

Plug your refrigerator back in. Within a few seconds, you should hear the new fan motor start up — it'll sound like a gentle whirring from inside the freezer. Replace your freezer shelves and drawers. The refrigerator section should start cooling down within 2-3 hours. Check the temperature after 24 hours to confirm everything's working properly.

Testing After Installation

Open your freezer door and listen for the fan motor. It should stop when the door opens (that's normal — it's a safety feature) and restart when you close it. Place a refrigerator thermometer in the fresh food section and check it after 24 hours — it should read between 35-38°F. If the fridge is still too warm after a day, check that the wire harness is fully connected and the fan blade spins freely. On models like the RFG297ABBP or RS267TDWP, there's also a defrost sensor clipped to the evaporator coils that can cause cooling issues if it got knocked loose during the repair.

Frequently Asked Questions

Will this DA31-00146E motor work on my Samsung model?

This motor fits most Samsung French door refrigerators manufactured between 2008-2018, including the RFG237 series, RF4289HARS, RS267TDWP, and RS25J500DBC models. Check the compatible models list on the product page or look up your model number to confirm. If your refrigerator is a side-by-side or top-freezer model, you'll likely need a different part number.

Why does my fan make noise after installation?

A new fan motor might sound different from your old one, but it should be a smooth, consistent hum. If you hear clicking or grinding, the fan blade might be hitting the housing or ice buildup. Power off the fridge, remove the back panel again, and check that the motor is mounted securely and nothing's obstructing the blade. Sometimes a small piece of ice or frost can cause this.

How long should a Samsung evaporator fan motor last?

Most evaporator fans last 5-8 years under normal conditions. If yours failed sooner, it might indicate other issues like the defrost system not working properly, causing excessive ice buildup that overworks the motor. If you're replacing this motor a second time within a few years, have a tech check your defrost timer and heater assembly — they might be the root cause.

The DA31-00146E also replaces older part numbers AP4136569, DA31-00146G, and PS4138376, so if you see those numbers in your refrigerator's service manual, this is the correct updated replacement.
