I have an old480 Kelvinator no frost refrigerator . The interior light has burnt out . Where is it and how and what do I replace it with

SOURCE: Major Appliance

It sounds like the thermostat is not sensing when the fridge/freezer reaches it's set temperature.This will result in the compressor running non-stop and this causes ice build-up inside the fridge.See on what number (0-7) the thermostat is set on.If it is set on 7,turn it down to 3 and see if it makes a difference.If there is no difference it means that the thermostat is not sensing & switching the compressor off.You will then have to replace the thermostat.
