A Bad Evaporator Fan Motor Causes Your Refrigerator To Get Too Warm Inside

If your refrigerator and freezer compartment aren't as cold as they should be, the problem might be with the evaporator fan motor. A warm refrigerator is a problem that needs quick repairs or your food will spoil fairly fast. An evaporator fan motor is somewhat difficult to replace since the refrigerator has to be taken apart to reach it.

Plus, the problem could be with the control board that controls the motor instead of the motor itself, so calling a refrigerator repair service for help could be the quickest way to get your refrigerator working again. Here's a look at the purpose of an evaporator fan motor, signs that it's bad, and how the motor is replaced.

The Purpose Of An Evaporator Fan Motor

The evaporator fan is in the freezer compartment of a refrigerator near the evaporator coil that contains refrigerant. The fan pulls cool air away from the coil and pushes it through the freezer and refrigerator. The motor is what operates the fan, so it's an essential part that keeps your food cold.

The Signs An Evaporator Fan Motor Is Bad

The fan might make odd noises when the motor is failing or when there is something stuck in the fan. However, you may not know anything is wrong until you open the refrigerator and find it is warmer than it should be and it doesn't cool off even if you adjust the temperature.

The Solution For Fan Motor Problems

The first thing a refrigerator repair technician has to do is determine if the motor is the problem or if another part is affecting the motor. If the fan blades, wiring, or control board are bad, the motor may not be able to operate, but the motor still might be good.

The refrigerator repair technician can test parts with a multimeter and check the blades for obstructions to determine what is wrong. If your refrigerator has a diagnostic testing mode, the technician may use it to do a fan test that helps pinpoint the problem.

If the motor is bad, it has to be replaced. This may entail dismantling the shelves and other parts in the refrigerator or freezer so the back panel can be removed. Once the panel is off, the technician can disconnect the wiring from the motor so it can be pulled out and switched with a new motor.

When the new motor is in place, your freezer and refrigerator should cool down nicely. If you adjusted the temperature when your refrigerator got warm, be sure the temperature is returned to its normal setting so the appliance doesn't get too cold when it starts working properly.
