Hi. Its either a bad motherboard or control board. I would check the control board for any obvious signs of damage to the board first. I've seen the control board go blank on the GE side by side and it turned out to be the motherboard. The motherboard is located behind a cover on the back of your refrigerator cabinet. You should have a new motherboard on hand at all times because they fail alot. Be sure to put a surge protector on your refrigerator. Good Luck, Mack

look open the freezer door pull the lower kick plate off look for a small little hole there its a mechanical timer model should be close to the wheel in that hole will be a plastic piece open the freezer door you will hear the fan running in the freezer take out the four or five screws on the lower panel where you keep seeing the frost and remove it you will see a silver honeycomb looking piece that's the evaporator on one of the tubes will be clipped a silver dome looking piece with two wires on it that's the defrost thermostat now turn the timer with a screwdriver that's the piece in the little hole slowly to your right till you hear a click and the fan stops in the freezer now as your turning it it will make a ratchet sound you want the click and the fan to stop look at your watch and note the time then wait about 5 minutes and look at the heater to see if its on if its all frosted up the frosted should look all watery if the heater is on then just let it run if not then reach up and turn the freezer control to the off position then un plug the two wires on the defrost thermostat and take the two wires that you unplugged the thermostat from and plug them back together and turn the freezer control back on and wait stay there and watch the heater come on let it defrost the evaporator if the heater comes on when you do that .that means the thermostat is bad if the heater comes on without you having to by pass it that means the timer is bad if you do all that and the heater does not come on then the heater element is bad now its going to get red like an oven and pop and sizzle but don't let it freak you out now if you had to by pass the thermostat and the timer cuts the compressor on before the frost is all clear just turn the timer around again till the fan cuts off and the heater will come back on if you by passed the thermostat then when all the frost is melted then reach up and turn the freezer control back off and reconnect the thermostat.Now after about 30 mins after turning it off the timer should cut back on if its not bad when you change the timer back out the two screws reach under the fridge and turn the timer and its shield till the screws are in the removal position when the timer is loose remove the shield and unplug the timer plug your new one back in then put the shield back on and back where it goes now id recommend changing both the timer and the thermostat as they fail pretty close together the stuff i described above is to make the unit defrost to save your food with out having to use your hair dryer also when all the frost is melted at he bottom of the evaporator on the right hand side is a hole in the cabinet that has to be clear of frost for the fridge to cool properly now any time during this defrost technique if you have a problem turning off the freezer cold control will turn off the defrost system too if i can be of help or you need to know something just reply to this post

It is an error code. The thermal fuse in the freezer section has gone. It has to be replaced. To get by in the short term, uplug the unit for 15 minutes, then plug it back in. It will run until it hits the defrost again (approx 5 hours) Part location is 401A and part number is 6615JB2005C. It is easy to change once you get the back cover off. Plug in part.

I am experiencing the same problem with my GE fridge. We have already tried the Turbo Cool, but nothing seems to help.

I was having the same problem but with the refrigerator side. I know your problem was with the freezer side but I hope this works in your situation too. I was also told to unplug the fridge for 20 minutes and that did not do a thing to reset the circuit board in my situation. Unplug the refrigerator first. In the back of the refrigerator at the bottom is a metal panel. Remove that panel and off to the right side of it should be a white looking plastic box. Unscrew that box from the fridge and open it up to get to the circuit board. Remove ALL harnesses from the circuit board and capacitor. After doing so plug them all back in and reassemble everything back together and plug in the fridge. This should reset the board and allow it to function correctly. This is advice I got from someone else and everything as of today is cooling down like it should. I hope this helps everyone else out. Best of luck.
Also since the evaporator was frozen solid at the bottom on the refrigerator side I had to leave the power off until it thawed and then had to soak up all the water that collected at the bottom of it.
