Kenmore freezer displays E7; interior fan may not run or may run erratically; temperature is uneven.

Safety first: Unplug the freezer before accessing the evaporator fan. Beware of sharp metal edges and ice.

Steps to address E7:

• 1. Access the fan: Remove shelves and the rear interior panel to expose the evaporator and fan assembly.
• 2. Check for ice blockage: Look for ice buildup around the fan shroud or blades. If present, fully defrost the area using towels and warm air (no sharp tools).
• 3. Spin the fan by hand: With power off, gently spin the fan blade. It should move freely without grinding. If it is stiff or seized, the motor is likely bad.
• 4. Inspect wiring: Check the fan motor connector and harness for loose pins or corrosion. Reseat the connector.
• 5. Test the motor: Disconnect the fan and measure resistance across the motor leads. An open circuit indicates a failed motor. On DC fans, verify correct voltage from the control board when powered (this test should be done carefully; if unsure, call a technician).
• 6. Replace the fan motor: If defective, remove mounting screws, transfer the fan blade to the new Kenmore-compatible evaporator fan motor, and reinstall.
• 7. Reassemble and test: Reinstall the rear panel, restore power, and confirm the fan runs and E7 clears after a short period.

Note: If the fan tests good but does not receive power, the main control board may be at fault and should be professionally evaluated.
