Understanding the Problem
What this part is and why it matters: The DA31-00146E is an OEM evaporator (freezer) fan motor used in many Samsung refrigerators. The evaporator fan circulates cold air from the freezer evaporator throughout the freezer and fresh-food compartments. When it fails you can get poor cooling, frost/ice buildup in the evaporator area, warm spots in the fridge, and loud or unusual noises. Step-by-step diagnostic and repair instructions: 1) Confirm symptoms: Open the freezer and listen while the compressor is running. If the fan is not spinning, making grinding/squealing noises, or only running intermittently, proceed to diagnostics. 2) Safety first: Unplug the refrigerator before doing any disassembly. If you must test with power on, be cautious — you'll be working around mains voltage. Use insulated tools and consider having a helper. 3) Locate the evaporator fan: Usually behind the rear inside panel of the freezer compartment (or behind an inner cover). Remove shelves and any drawers, then remove the back panel screws to expose the evaporator and fan assembly. 4) Visual inspection: Look for ice blockage around the fan blades (common if defrost failed), damaged/bent blades, or disconnected wiring. Remove any ice or obstructions and check blade spin by hand (should turn freely with slight resistance from motor bearings). 5) Check power at the connector (advanced): With the fridge plugged in and thermostat calling for cooling (compressor on), carefully measure voltage at the fan motor connector. If you see the expected voltage (typically 120VAC on many models — check your model's wiring) and the motor doesn't run, the motor is bad. If there is no voltage, the problem may be the defrost board, main control board, thermostat/thermistor, or wiring harness. 6) Check motor windings: With power disconnected, use a multimeter to check continuity between motor leads. A totally open winding (infinite resistance) indicates a failed motor. Very low resistance or short to ground also indicates failure. 7) Decide replacement vs repair: If the motor is noisy, won't spin, or shows open windings, replace it. If the problem was only ice/obstruction, clear the ice and test — but investigate why the ice formed (defrost system fault). 8) Replace the motor (basic steps): - Tools: Phillips and nut drivers, putty knife or panel tool, multimeter, replacement DA31-00146E motor. - Unplug refrigerator and remove all freezer contents, shelves and drawers. - Remove the freezer rear panel to access evaporator and fan assembly. If excessive ice is present, defrost manually first (turn off fridge and let melt, or carefully use hairdryer with caution). - Remove fan shroud and disconnect the motor's wire connector. - Remove screws or clips holding the motor and pull the motor and blade straight out. Keep track of any rubber grommets or spacers. - Install the new DA31-00146E motor, reattach the fan blade (ensure correct orientation), secure mounting fasteners, and reconnect the wiring harness. - Reinstall panels, shelves and drawers. Plug the fridge back in and verify the fan runs when compressor cycles. Monitor temperatures and check for abnormal noise. 9) Final checks: Allow the refrigerator several hours to stabilize. Ensure even cooling throughout compartments and that no excessive frost reappears on the evaporator (that could indicate a defrost issue). Safety note: Always unplug the refrigerator before opening panels. When measuring live voltage or applying power to test, take extreme care — if you're not comfortable testing live circuits, hire a technician.
Common Symptoms
Noisy fan (grinding/squeaking), fan not spinning, poor or uneven cooling, freezer warming, frost/ice buildup on evaporator.
Common Causes
- Worn bearings or seized motor windings in the evaporator fan motor
- Ice/obstruction preventing fan blades from turning (often due to defrost failure)
- Wiring harness, connector, or control board failing to supply power to the fan

Helpful Repair Tip
Before buying the motor, confirm your refrigerator model number (from the tag inside the fridge) and visually match the motor connector and mounting; also try turning the blades by hand — a stiff or seized spin usually means the motor is bad.
Frequently Asked Questions
How do I know DA31-00146E is the correct part for my Samsung refrigerator?
Check the model number of your refrigerator (tag usually inside the fresh-food compartment or behind a kickplate) and confirm parts compatibility using that model. Also compare the motor's physical mounting, blade shape, and electrical connector to the replacement part images. If in doubt, input your fridge model into a parts supplier search or contact Samsung support.
Can I replace the evaporator fan motor myself or do I need a technician?
Yes — many homeowners can replace the evaporator fan motor with basic hand tools and a multimeter. The job requires removing interior panels and working near the evaporator; you must unplug the appliance and exercise caution when testing live voltage. If you're uncomfortable with electrical testing, working in tight spaces, or diagnosing control/defrost issues, hiring a pro is recommended.
