Weeeyup-weeeeyup type wind up noise from top of unit. Can not detect the source. New Evap fan & bushings installed. Any Assistance????

Your freezer motor is probably too loose, add some rubber gromets to the end bells to stiffen them up.

I have replaced the evap motor & bushings.

This is not constant noise, like a fan running. When the unit is running the sound is coming from the middle upper right on the back/while facing the back. The sound is more pronounced from the outside with little noise from the inside. Icemaker works-no frost build up inside-all compartments cooling-solenoid type wind up noise-like something to engage.

The noise may be coming from the evaporator capillary line. You might have refrigerant contamination, measure the freezer temperature and post.

Freezer temp 8 degrees, control setting #3. I removed the inner freezer panels, the evaporator was frosted /not frozen over. Using my pinpoint stethoscope, the noise was coming from the top of evaporator by the insulated bulb & capillary line. I defrosted the evap with a hair dryer-less noise now. Possible defrost timer and or heating element???? What is your opinion?? Should the evaporator coils be free of frost completely when checking out this issue??? Thanks

You may have had only a partial defrost, most likely a defrost thermostat going bad, I would probably replace it.
Your freezer temperature must be lower now, just check and post.

Freezer at 0 degrees-very noisy last night again. I will pull the panels again and defrost with hairdryer if needed. Should I purchase the heating element/thermostat assy and a defrost timer?? OR which unit should I purchase and replace first to solve this issue? Thanks

Your problem is not a defrost problem. If the lowest temerature the freezer will go down to is zero, you might have a partial restriction in the capillary line.
