I have a Whirlpool refrigerator model# EHT-201Zk, and I believe the evaporator motor is going. It is making a loud noise in the freezer area. It is still cold but just this noise keep coming off and on.
Is this something that I can replace, having no experience, or do I need to call someone. Please advise. Thanks.

Re: Evaporator Motor & Fan
you can try to completely defrost the fridge by unplugging it for a day and put you groceries in another fridge, sometime ice dams build up in those and freeze next to the fan blades and cause alot of noise, if its squealing, then its the motor for sure, evaporator motors are usually pretty easy to replace once you study where its at, usually the whole top or bottom and back of freezer has to come out then the motor and fan are right there, keep the fan blade assembly because you put that on the new motor, be extremely careful once you have the bottom and sides out because the coils will be vulnerable to anything if you hit them go to www.sears.com and go to parts area, theres a sears repair store in our town , hopefully in yours or just call around, dont forget to unplug it! hope that helps

If the noise is coming from inside, the evaporator fan motor (the fan motor that circulates cool air located in the freezer section) may be the culprit. If noise is on the outside, the condenser fan motor may be the problem. This is the fan motor that removes the heat from the refrigerator to the room.
i quick fix would be to take a quart of oil and remove the fan motor and soak it in the oil. This wont hurt it anter a couple of min in the oil, hang up so that all the oil can drain off it, then wipe it down. install motor and try again, let me know.
If it is cooing fine, then the noise is probably your evaporator fan (the one inside your freezer). This can be cause by one of several things. The motor on this fan may be going bad, or, more likely, you may have a build up of ice around the blades that are touching the fan. This may be caused by a defrost circuit that has gone bad, or, the freezer may have been open alot lately and there is an excess of frost that hasn't melted away yet. If you can, manually defrost the freezer and see if it goes away. If it doesn't, it's probably the fan motor. If it does, and then comes back, it's probably the defrost circuit. Hope this helps!
Below is a link courtesy of www.repairclinic.com, that shows the evaporator fan blade. This may have come loose from the fan motor shaft and may be striking the fan shroud or rattling on the motor shaft
A loose fan blade cause elevated temps. If the fan blade is loose, replace it, not repair it, to avoid further problems.
Sounds as if the evaporator fan has shaft play or the blades are out of balance or striking something. When you open the door the pressure is equal but with the door closed the fan needs to push the air through the evaporator and return again and circle through fan again. I think soon would be a good time to unplug the refrigerator and remove the back panel covering the evaporator and fan motor to inspect the fan, shaft play and the evaporator for frost buildup or any obstruction of air flow.

Check for frost build-up behind back wall in freezer. If there is a heavy frost build-up, it's not defrosting. This will restrict airflow to refigerator section and can stop fan. If fan is stuck again and it's not because of frost, replace evaporator fan motor.
I believe you will trace this noise back to the evaporator fan motor inside the freezer making the noise. If you agree that the noise is coming from the evaporator fan motor inside the freezer it is not the motor that is responsible. Your model has a Main Mother Board on the outside rear wall of the freezer down low (about 10 screws hold square cover on over board). The Main Board is causing your noisy evaporator fan motor. Use caution when handling any electronic circuit board. Follow antistatic cautions. Static electricity in your body can damage these valuable circuit boards.
