Even though it is frost free, try defrosting it by turning it off with the doors open for a few hours. There may be ice or something else blocking the vent between the freezer and refrigerator sections. Of course you will need to remove everything from the fridg and freezer and store it somewhere else that is cold.

A frost free freezer typically relies on a "fan" to vent that area of moisture. So, if the fan/vent is not working properly, the moisture in the freezer stays and become frost. Frost can also form if / when the freezer door is not closing properly / completely ... allowing air / moisture to enter the fridge/freezer . Have those checked out first.

I would recommend that you turn either the freezer down or the fridge. This is somewhat normal, even frost free units will produce some frost, and this is mainly due to the temperature being too cold. Some minor adjustments and you will be fine.

what you need to do is get rid of the electrician, and get a refrigeration service man and he wont need the wiring diagram.

change the timer

The fridge need to be devrosted open up freezer door take back of and look if all ice gone from freezing rods restart if same prob it looks like fan not going or heating element not workingon

Your refrigerator is likely a frost free model. There is a heating element that runs around the freezer compartment. It is probably the heating element that is causing the original damage to progress.

Most fridges have a way to turn off the frost free part, usually via the timer or or easy as pulling the fuse for the circuit. Pull the fridge out, climb behind it, unplug fridge, and remove access cover, if equipped. Look for a wiring diagram. It will tell you where you need to disable the frost free at.

If you can't disable the frost free, then replace fridge now. the acrid smoke you smell is toxic, and is detrimental to food, as well as to human life. Stop using the fridge, or disable frost free.

Are you frosting up at the condensor or did you mean the evaporator? If its the condensor then make sure the coils are clean. Still then you will need a tech to look at the seale system. If its the evaporator and the heater is ok then it could be the timer or the terminator on the compressor. Most of the time its the timer.
