Kenmore Refrigerator: evaporator fan motor failure

Professional Repair Guide

What is this symptom?

Experiencing Kenmore refrigerator evaporator fan motor failure? This issue prevents cold air circulation, leading to warmer temperatures in the fridge, unusual noises, and possible frost buildup. The fan, located in the freezer compartment, should operate when the compressor is running. If it's not running, it could indicate a mechanical failure, obstruction, or electrical issue.

Urgency: High

Important Tips for Kenmore Models

  • No specific manufacturer troubleshooting guide found but general evaporator fan failures apply across models.

Possible Causes

Faulty evaporator fan motor (mechanical/electrical failure)

How to Identify: Fan does not spin when door open and compressor running, no airflow in fridge, unusual noises like grinding or humming.

Part: Evaporator fan motor

Ice or frost buildup obstructing fan blades

How to Identify: Visible frost or ice blocking blades, fan hard to spin manually, excessive frost on freezer back wall.

Part: Evaporator fan assembly / coils area

Electrical issue — wiring or control board

How to Identify: Fan doesn’t run but motor shows continuity, diagnostic mode test runs fan but normal operation doesn’t, visible wire damage. (Sears Parts Direct

Part: Wiring harness or control board

Wear and tear / power surge damage

How to Identify: Older fridge, motor makes unusual noises before stopping, previous power events, increased energy use. (Sears Parts Direct

Part: Fan motor electrical windings/bearings

DIY Solutions

Inspect and Clear Obstructions Around Evaporator Fan

Moderate 30–60 minutes
Tools Needed: screwdriver, flashlight
  1. Unplug refrigerator and remove all items from the freezer.
  2. Remove the rear access panel to expose the evaporator fan.
  3. Visually inspect for ice, frost, and debris blocking blades.
  4. If ice present, defrost by unplugging and letting unit thaw or gently remove ice.
  5. Ensure blades spin freely by hand, reassemble and test.
  6. Plug refrigerator back in and check fan operation.
⚠️ Safety First: Always unplug before internal inspection to avoid shock.

Test Fan Motor With Multimeter

Advanced 45–90 minutes
Tools Needed: multimeter, screwdriver, safety gloves
  1. Disconnect power to refrigerator.
  2. Access evaporator fan behind freezer panel.
  3. Disconnect fan motor wiring harness.
  4. Use a multimeter to check continuity of motor terminals.
  5. Compare readings to expected specifications (open circuit indicates motor failure).
  6. If motor shows no continuity, replace motor with compatible part.
⚠️ Safety First: Unplug fully before testing electrical components.

When to Call a Professional

If multimeter testing or internal access is beyond comfort level.
Persistent issues after obstruction removal and motor replacement attempts.
Evidence of control board or wiring issues beyond basic DIY troubleshooting.

Preventive Maintenance

  • Defrost freezer and clean around evaporator fan: Ice buildup blocking fan blades and premature motor strain.
    Frequency: every 6–12 months
  • Vacuum coils and airflow areas: Dust accumulation and airflow restriction that could overheat fan motor.
    Frequency: annually
