Frigidaire Uprt Frzr FFU2064DW1 Burnt Plastic Smell

[sun_lover]

My husband died 3 years ago. He was the half of us who fixed appliances. I am pretty handy, though -- at 73, I am working on doing these things myself. (So far I have repaired my stove. Youtube helps.) My huge Frigidaire upright freezer started smelling like burning plastic, but I could detect no discernible change in its freezing ability. Fearing a fire, I unplugged and emptied it. The back panel does not screw on or off. All the parts are down at the bottom, although I can periodically hear (when I plug it back in for a bit) a raggedy noise coming from about halfway up the back. Something does come on and runs with a steady hum -- I presume the compressor. How do I diagnose what might be wrong? I am presuming a fan, but I cannot see anything that isn't working properly. When I plug it back in, the burning smell returns, but I can see no moving parts.

Thank you for any help you can give me!

(When I save the pics on my computer, they are oriented correctly. When I paste them, they flip. The "freezer bottom" pic is upside down. I do not know how to fix this.  am sorry.)

Is the burnt smell inside or outside of the freezer?

Outside.

Since the smell is on the outside of the freezer the would leave the compressor or an electrical connections. Next would be to plug in the freezer, then try to find the area that has strongest smell of burning. Once you find the general area of strongest smell unplug the freezer. Then look over the wires/ components for burn marks or discoloring. Don't forget to include the wall outlet and power cord.
