Question about Refrigerators
Either you've got a leaky door seal, or your defrost timer, heater or
thermostat isn't working. If it's the door seal (easy to check with a
business card, just insert it between the seal and the fridge, if it you
can slide it in easily at any point around the door, the seal is
loose), then just replace the seal or realign the door to seal properly.
Now the defrost heater. Every now and then, the timer tells the heater that it's time to get to work, while telling the cooling parts to take a break. The timer turns on a heater, usually located in the back panel of the freezer, which warms the panel, which melts the ice, and the melted water drains, through a hose, into the drain pan in the bottom of the fridge. When the cooling unit turns back on, the fan blows air over the pan and the water evaporates.
Everything is wonderful until one component of the "automatic defrost" quits working.
The heater and thermostat both require a continuity test. The motor can often be seen or heard to be moving (if you can hear it, it's ok.
Testing and replacement are not too difficult. (Hey, I've done it) A continuity tester is essential. A multimeter or voltage detector can be helpful. For replacement parts, either call your local appliance parts place, or google your model# and "parts", for example- " A4112030642 parts".

Oncce the fridge was shut off and left for a while the cooling had come back . If frost is seen it is a good indication as the compressor is working with sufficient gas within.
If after about 6 hours you observe cooling it is possible that the defrost timer is faulty.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if Ice forms then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
replace the defrost timer, heater or thermostat one you have confirmed to eliminate one by one.
