If your freezer or fridge are not getting cold enough, there are a number of things that could be going wrong. You might have too little or too much food in the fridge, or you might have bumped the settings. Perhaps your condenser coils are covered in dust and therefore less efficient. But if you’ve tracked it down to a non-spinning evaporator fan, then this is the repair guide for you.
The evaporator fan pulls air over the cold condenser coils, bringing the cold into your freezer and fridge unit. Today, we’re going step-by-step through the process of replacing the motor for that fan in a top-freezer refrigerator.
These instructions are generalized and can vary by brand or model.
Start by gathering all the tools you’ll need for this repair. Naturally, you will need the correct replacement motor. Find this by researching your fridge’s make and model and identifying the correct part number to order. For the rest, you’ll need work gloves, a nut driver set, and needle-nose pliers.
Take all the frozen food out of your freezer and move it to the refrigerator section. Pack it tightly together near the back to help it stay cold while you perform this repair.
Try not to keep the fridge open too long and shut it tightly to contain cold.
For your safety, because this is an electrical repair, you’ll need to unplug the refrigerator before opening up any panels. Then put on your work gloves.
Now pull out the shelf or shelves in your refrigerator’s top-freezer section. Use releasing clips or lift and twist as is appropriate for the type of shelf you have. Set the shelves aside.
You will see a panel with vents in the back of your freezer. This is the evaporator cover. It is secured with four to six screws. Remove them with the appropriate size nut-driver or screwdriver based on the type of screw. Set the screws aside for later.
Pull the top of the evaporator cover down, revealing the wires that connect it and the fan (your target) mounted on the inside.
Snap a phone photo of the wiring before disconnecting anything. This will give you a point of reference to be confident when you reinstall the panel later.
Unplug the wiring clip that connects to the evaporator fan.
Pull the green wire which is your electrical grounding wire from its socket.
Unplug the wiring clip that fastens the panel to the ice maker, if you have an ice maker.
Now you can fully pull out the evaporator cover. Place it on your work surface where you will perform the rest of this repair.
There are two narrow locking rings on either side of the plastic fan housing, holding it in place. Remove them with your needle-nose pliers and carefully set them aside. You will need them later.
The fan cover is an extra piece of plastic connected by tabs that will pull away from the evaporator cover. Hold it down while lifting the evaporator cover and it should snap away. You may need to press a few tabs for a clean disconnection.
Pull the fan cover panel away and set it aside.
Turn the panel over so the fan blades are exposed and pull the fan blades off of the motor shaft. Set the fan blades aside.
Turn the evaporator cover back over and lift the two locking tabs on the top of the plastic fan housing with needle-nose pliers
Rotate the motor retainer on top counter-clockwise to unlock and remove.
The old motor is the block you see underneath. Remove it and throw it away or save it for electronics recycling.
Place the new motor inside the mounting bracket, exactly how you found the old motor.
Place the motor retainer back on top and rotate it clockwise to lock it in. The tabs should click by themselves.
Flip the evaporator cover again to replace the fan blades on the new motor shaft.
Snap the fan cover that protects the exposed fan blades back into place. Its tabs should also snap back in by themselves.
Retrieve the two locking metal rings and return them to their places with your needle-nose pliers.
Finally, you can place the evaporator cover back in the freezer. Make sure it is right-side up, and ready to receive wiring.
Reference your phone photo to return the fan wiring clip, green grounding wire, and ice maker wiring clip to their proper positions.
You’re almost done. Align the evaporator cover back into place by setting the bottom and folding it upward, just as you removed it before.
Return the mounting screws with your nut-driver or screwdriver and secure them firmly.
Reinstall your freezer shelf or shelves, remember that you may have to twist them to fit or lock them into place.
You are finally ready to refill your freezer with all the frozen goods. Make sure not to block the vent between the fridge and freezer while refilling.
Now you can safely plug your refrigerator back into the wall and return its power.
Give your fridge and freezer a little closed-door time to rebuild the cold. If your repair was successful, this should work.
Open your freezer and place your hand near the back. If you hear a whir and/or feel airflow, that new motor is working like a charm.
If you just confirmed that the evaporator fan is spinning again, give yourself a big pat on the back. You just performed a fairly complex repair that would normally require a visit from your friendly local repair service.
