Freezer and refrigerator stop cooling, back of freezer compartment frosted over. slight running sound for refrigerator.

here are lots of things that can cause cooling problems. One of the most common causes of poor cooling in a frost free refrigerator is a defrost system failure. In such a case one or the other compartment may appear to be keeping proper temperature but that too may change in a short period of time. The fridge compartment's temperature rise is usually (but not always) the first to be noticed. Frost" and "Ice"
There is a difference between "frost" (a white, snow-like substance) and "ice" (usually clear and solid). When referring to what is seen during an inspection, please keep this distinction in mind as the possible causes for each are often very different. The Defrost System
Inspecting the (usually rear) wall of the freezer compartment for a frost build up is necessary. (In the case of many GE top freezer models, check the freezer's bottom panel.) If there is a frost coating on it, it is often a sign of excessive frosting beneath it. Sometimes however the evaporator cover panel will actually need to be removed (see the illustration below) before an excessive frost build will visible.
The refrigeration system's evaporator (cooling) coil is usually in the freezer compartment. This evaporator will periodically frost over and have to be defrosted by means of a heating system. When the defrost heating system fails, the frost can accumulate to such a degree that airflow throughout the appliance is hampered. There may be just enough air circulation to cool the freezer section but that will eventually stop too.

Sounds like a defrost heater has gone out. If the frost is in the back of the freezer, it will get worse and worse until it stops cooling. You can either unplug the unit for 12 hours, let all the frost melt and then turn it back on. Or replace the defrost heater.

The problem you describe is that your defrost circuit has failed. The fridge should stop the compressor periodically and turn on the defrost heater to melt the frost buildup. Since the frost in building up on your coils, the fan can't blow the cold air into the fridge compartment. It defrost is controlled by a module that turns on the heater. Most of these failures have to do with the defrost heating element burning out. It can be replaced by someone who has some mechanical ability.

The coil and heater is located in the back of the freezer compartment behind the panel in the back. You can obtain parts from appliance repair outlet or online like appliancepartspros.com or repairclinic.com.

Had exactly the same problem.
It was due to a blockage of the drain.
At the back of the freezer there is the pump and there is a small darin that lets condensation from inside the freezer spill onto the top of the (hot) pump to be evaporated. When this small drain blocks it causes issues like water leaking out of freezer and big chunks of ice at the back of the bottom compartment.
The fix is easy, if a little laborious.
Take all the stuff out of the freezer, then dismantle the internal plastic trip, don't worry, you can't really break anything and it goes back together easily, Eventually you will be left with just the bare metal insides and in the middle at the bottom back you will see the drain collection point, slightly hidden from view is the drain hole. Pour warm water onto this till it comes out onto the pump at the back.
Then use a pipe cleaner to clean.
Re-assemble - done :)

Sounds like the defrost timer is not tracking the time properly. The unit needs to defrost once every 6-8 hrs. in order to work. Make sure the inside (evaporator) fan is running ok. If it rund for a few days and then warms up in the refrigerator section (coil iced), then the defrost timer is the culprit.

temp control wire dodgy turn off take plug out of socket trace wire repair it switch back on i had one temp mate it was wire

is the freezer fan running?is there any frost in the freezer?can you pull the frig. out and see how hot it is?is the comp. fan running?is the comp. clicking on and off,let me know what you find-mike

Same problem here with an Amana refrigerator with the freezer on the bottom. I removed the back panels and vacuumed dust and cat hair out. The back panel in the freezer was frosted over with ice on the bottom. I removed the shelves and food and used a hairdryer to loosen the panel. The ice maker made it harder to remove the plastic panel so I pulled it back and saw the cooling fins frozen solid. I used the hairdryer to melt the ice and a shop vacuum to collect the water. It works like new again.
