Kenmore Elite not cooling/freezing evaporator not getting cold, burn marks

Hello All, I have a relatively new Kenmore Elite 795.7205 that is no longer cooler/freezing. What a way to start the day after the 4th…

After a trip to Sams club for a new freezer, so we don’t loose all our food, I started to troubleshoot the problem and discovered the following at the evaporator coil:

There was a black tape/shrink tubing around the sections that appears to have gotten really hot and burned/melted.

The Defrost element is on the opposite side for this model, and the connection is still pristine. I have also tested all the fans and all is well.

What would cause this to get so hot?

Do I need to replace the evaporator coil and recharge the system?

Hi.

When you turn the refrigerator on do all the fans and compressor runs? Do the evaporators get frosted?
Also, please provide the complete model number.

Thank you,

Simon.
