Understanding the Problem
What this part does: The evaporator (evap) fan motor circulates cold air from the freezer evaporator coil through the freezer and refrigerator compartments. If it fails, the fridge will run but not cool properly, the freezer may be warm, or you may hear grinding/noise. Step‑by‑step diagnostic and repair instructions: 1. Verify symptoms: Confirm fridge/freezer not cooling, uneven temperatures between compartments, excessive frost on the evaporator, or loud fan noise coming from the freezer section. 2. Safety first: Unplug the refrigerator or switch off its breaker before accessing internal components. 3. Locate the evap fan: Open the freezer and remove shelves and drawers as needed. The evaporator fan is behind the evaporator cover (back panel inside the freezer compartment). 4. Remove the cover: Use a Phillips screwdriver or nut driver to remove screws and carefully pull off the evaporator cover to expose the fan assembly and coil. 5. Visual & manual check: Inspect for ice or debris blocking the fan blade. Try to spin the fan blade by hand—if it does not spin freely or feels gritty, the motor bearing is suspect. 6. Electrical check (multimeter): With power restored only when necessary and at your comfort level, reconnect power and measure voltage at the fan motor connector while the compressor is running (typically ~120VAC on U.S. models). If proper voltage is present but the motor doesn't run, the motor is bad. Alternatively, with power off, test the motor windings for continuity (low ohms expected) — an open winding indicates failure. 7. Inspect connectors and wiring: Look for burnt, corroded, or disconnected wires and connectors. Repair any wiring faults before replacing the motor. 8. Order the right part: For Samsung RFG237 series refrigerators, the common OEM evap fan motor replacement is listed under Samsung evaporator fan motor assemblies (example OEM reference: DA31-00020A). Verify compatibility by checking the model tag on your fridge and matching the existing motor's mounting pattern and connector. 9. Remove the faulty motor: With power off, disconnect the fan motor wiring harness. Remove mounting screws/clips holding the motor bracket, pull the fan blade off the motor shaft (note orientation), then remove the motor from the housing. 10. Install the new motor: Transfer any mounting brackets or spacers, press the new blade onto the motor shaft until seated, bolt the motor/bracket back into place, reconnect the wiring harness (match wire colors or connector keyed), reattach the evaporator cover, and restore power. 11. Test operation: Run the fridge and listen for the fan. Verify airflow from freezer to fridge and monitor temperatures over the next 24 hours. Safety note: If you're not comfortable testing live voltage or disassembling the freezer evaporator area, or if the evaporator area has significant ice (indicating a defrost issue), consult a qualified appliance technician. Always disconnect power before working on internal components.
Common Symptoms
Freezer or refrigerator not cooling, no airflow between freezer and fridge, loud grinding or rattling noise from freezer, fan blade not spinning, or frost/ice buildup on evaporator.
Common Causes
- Worn motor bearings or seized motor
- Ice or debris blocking the fan blade
- Open motor windings or internal motor electrical failure
- Damaged wiring or connector preventing power to the motor
- Control board/relay faults (less common) that fail to power the fan

Helpful Repair Tip
If the compressor runs but you can feel little or no cold airflow from freezer vents and the fan blade will not spin freely by hand (or hums), the evaporator fan motor is almost certainly the culprit—verify by checking for 120V at the motor connector while the compressor is running.
Frequently Asked Questions
How do I confirm the evaporator fan motor is bad?
First, listen for noise from the freezer and try to spin the fan blade by hand with power off—if it’s stiff or gritty, the motor is bad. With proper safety, restore power and measure for voltage at the motor connector while the compressor is running—if voltage is present (typically ~120VAC) but the fan doesn’t run, the motor has failed. With power off, a multimeter continuity check that shows an open circuit on the motor windings also indicates failure.
Can I replace the evaporator fan motor myself and how long does it take?
Yes — a homeowner with basic tools and comfort working on appliances can replace it. Typical tools: Phillips screwdriver, nut driver set, multimeter, and possibly needle‑nose pliers. Procedure time is usually 30–90 minutes depending on access and whether ice needs defrosting first. Always unplug the refrigerator before starting, photograph wiring for reassembly, and verify the replacement part matches mounting and connector types before installation.
