I have an older Kenmore model 363.68287891. It's freezing on top and not real cold on the bottom. The motor or condensor is running, but when it stops, it makes a loud noise.

You are probably correct that it is the evap motor. If you are seeing frost on the back wall then there is probably some ice built up around the motor and the fan blade is hitting it.
Try defrosting the freezer and look very closely all around the seal for the freezer drawer. It is common for moisture to freeze in the self closers in the drawer rails and not let the drawer close completely on one side or the other. If this happens the small gap will allow the freezer to frost excessively.
Sorrry to be slow in responding. I have been very busy this week and have not been on line very much.

Check out this you tube. Had the same problem today. Tipped washer on its side and replaced coupler between motor and gearbox. Parts are about $15
This is a good diagnosis video.

It sounds like the evaporator fan is hitting ice that is built up on the evaporator coil. When it's making the noise, open the freezer door and see if it stops.
(Most models are wired so that the evaporator fan cuts off when the freezer door is open.)
Check the inside back, lower panel of the freezer for ice built up or frost on it. If there is, you have a defrost problem that is most likley a bad heater. It's located around the coil inside the freezer behind the panel you will be looking at. The defrost problem would explain the freezer not freezing ice cream.

Testimonial: "I turned off the freezer side and it defrost for a few hours. Then I turned it back on and its working fine for 2 days now. "

SOURCE: Kitchenaid Dishwasher has starting making a real loud noise

Hi Andy and welcome to FixYa. I am Kelly. That loud noise your hearing is the motor bearings. If you were to remove the lower kick panel you will prbably find signs of a slow leak of water has been trickling through the motor and you will see a water spot under the motor pump assembly.
You were correct in your assumption that it was bearings. What happens is the motor shaft ceramic seal starts leaking long before the home owner even notices it. Then the water gets into the motor and corrosion starts to build up. As the motor turns the bearing starts to spal as a result of the corrosion and you hear the loud noises.
The only fix for this sadly to say is a complete motor impeller assembly replacement. If your model number is the one associated with this post / question: KUDI01FLSS then there is one more digit after the last "S" that being one of the following numbers 0, 1, 2, 3, 4, 5 or 6.

The motor and impeller for your dishwasher Item 10 or 18 can be found here and is listed at $138.44:

The seal that has failed is item 23 of the same link. Changing the seal at this point will not stop the noise.

Thanks for using FixYa.
