Whirlpool Refrigerator Evaporator Fan Motor Repair:... | appliancefaults.com

Technical Background:

The evaporator fan motor circulates cold air throughout the refrigerator. The MCU (Main Control Unit) sends 12V DC to the evaporator fan motor through a wiring harness. If the fan motor is not running, the refrigerator's cooling efficiency is significantly reduced.

Symptoms:

US homeowners notice the refrigerator is not cooling properly, especially the freezer section. There may be excessive frost buildup or unusual noises coming from inside the freezer. Food may spoil quickly.

Possible Causes:

Dust and debris accumulation on the fan blades and motor housing.
Pet hair obstructing the fan's rotation.
Lack of regular cleaning and maintenance.
Motor bearing failure due to contamination.
Ice buildup impeding fan movement.

Solution:

1

Unplug the refrigerator from the 120V AC outlet.
2

Locate the evaporator fan motor inside the freezer compartment behind the rear panel.
3

Remove the rear panel using a 1/4-inch nut driver to access the fan motor.
4

Inspect the fan blades and motor housing for excessive dust, pet hair, or ice buildup.
5

Carefully remove any debris using a soft brush or vacuum cleaner attachment. Be gentle to avoid damaging the fan blades.
6

Check the fan blade spins freely by hand. If it's still stiff, the motor bearings may be failing and require replacement.
7

If the fan spins freely after cleaning, reassemble the refrigerator, plug it back in, and monitor fan operation.

Safety Warning:

Always disconnect the refrigerator from the power source before performing any maintenance or repairs. High voltage is present when the unit is plugged in. Lock Out/Tag Out (LOTO) procedures should be followed to ensure safe working conditions.

Prevention:

Clean the refrigerator's interior regularly, paying close attention to the evaporator fan area. Vacuum around the refrigerator, especially underneath, to minimize dust and pet hair accumulation. Consider using an air filter inside the refrigerator to reduce airborne particles.

Expert Tip:

Many Whirlpool refrigerators have a service mode. To enter service mode, typically press and hold the door switch while pressing the 'Warmer' button three times within 6 seconds. This allows you to manually test the evaporator fan motor.

Frequently Asked Questions

•How do I access the evaporator fan motor on my Whirlpool refrigerator?

You'll need to remove the rear panel inside the freezer compartment. Typically, this involves removing screws with a 1/4-inch nut driver. The fan motor is located behind this panel.

•What voltage should the evaporator fan motor be receiving?

Most Whirlpool refrigerator evaporator fan motors operate on 12V DC. Use a multimeter to test the voltage at the motor connector.

•If cleaning doesn't fix the problem, is it better to replace the fan motor or the entire refrigerator?

Replacing the evaporator fan motor is usually more cost-effective than replacing the entire refrigerator. A new fan motor is relatively inexpensive and easy to install.
