04 - Freezer Start Device

The compressor start device, also known as a start relay or start relay and overload kit, may have failed. This will usually cause the compressor to not start. If the burning smell is coming from the compresser area check the start device. If the start device smells burnt, or the compressor is trying to start but can't, the start device is likely bad and will need to be replaced.
Highly Likely

05 - Freezer Control Board

The freezer control board is usually located on the rear panel of the appliance. If the board shorts out or is damaged by a power surge, it can produce a electric burning smell. Inspect the control board for any burn marks and replace if necessary.

06 - Freezer Main Control Board

07 - Freezer Light Bulb

Higher wattage light bulbs (75 -100 watt) can heat up quickly, start melting the plastic liner, and produce a burning smell. Make sure a 40 watt or lower light bulb is installed, which is standard for freezers. If you're not sure, check the owner’s manual.
