After replacing the defrost heater, main board and thermistor I still had the same problem. Called a repair guy and he (with the help of GE on the phone) diagnosed that the temperature sensor was bad. So I ordered from partselect and installed it and it fixed the problem. Been good for a couple months (knocking on wood). To install I had to cut the 2 wires to the old sensor, crimp the 2 new wires on and snap the new sensor to the clip on the evaporator. Very easy. Make sure you seal the ends of the wire crimps so moisture doesn't get in and corrode the connection.

The freezer in my side-by-side kept warming up -- often 20 degrees or more, which of course caused the fresh food side to warm up also. I do a lot of jump-in-with-both-feet home repairs, but never on a large appliance. Not having an ohmmeter, which cost about $100 for a reliable one, I took the symptoms to the internet. Countless self-help sites and U-Tube videos later, I was positive it was one of two possible problems, either the defrost thermostat was broken and the defroster wasn't coming out of its cycle or the temperature sensor wasn't reading the correct temp and thus kicking in the fan motor when needed. Fortunately I found both parts easily on PartSelect.com and the total cost for both, including shipping, was $30, less than 1/3 of the cost of an ohmmeter. Not knowing for sure which part it was that was bad, I ordered both, figuring, since I had to pull out the panel anyway, I might just as well replace them both ... the price was right. (In retrospect I should have order 4 Temperature Sensors as my fridge has two in both the freezer side and the Fresh Food side. Any one of them being bad could have caused the same problem. Fortunately, I was lucky because it was either ONLY the Defrost Thermostat or I just happened to pick the right Sensor, but the repair worked.)

The repair was easy: Unplug the power. A Nut Driver removed the four screws holding on the panel in the back of the freezer. A screw driver removes the one screw holding the lamp cover in place. Remove the light bulbs, pull off the panel and right above the freezer coils you'll see both parts -- plain as day. (If your coils are clogged with ice, you will probably need de-ice first.) Cut the wires to both parts as close to the parts as you can to leave as much wire exposed as possible. Strip the ends of all four wires about 1/2 inch and also on the new parts. Match up the wires in the fridge to the wires on the parts and twist the ends together (Note: both wires on the Sensor are white so they match up either way, but the two wire on the thermostat will need to match up orange to orange and pink to pink.) I used silicone filled wire nuts, which you can buy at any hardware store or use your own wing nuts and fill them with silicone or shoe goo which works just as well ... anything to keep the moisture out and prevent the wires ends from corroding. Tuck the wires up and replace the panel, light bulbs and light cover That's it. Very easy. By far the hardest part was wedging my wide body into the narrow freezer compartment. Some one-handed work added a little extra time to the project.

In my case the freezer fan didn't kick in for about twenty minutes after I plugged it back in, but I assume that it either begins in the defrost mode or it takes that long for it to reset itself ... either way the repair worked great.

I went to a GE repair center to explain my problem, the service center reccomended that I have a techinician come out o look at it. $75.00 for the visit and what ever labor and materials wuld cost.

I went on line to see if there were others having this same problem and found that there were many with the same problem.

After reading some of the ways that people found out what was wrong ...it became a matter of three components, the timer, heater or thermostat.

I tried the most common component and the less expensive one first , the thermostat switch I installed it very easily snipping two wires and attaching the news using wire nuts I used the diagram on this website to pinpoint the component and there has not been a problem since.

I removed the old temperature sensor by cutting the wires. I attached the wires of the new sensor with wire nuts and mounted it in the same bracket.

First unplug then remove all food and the ice cubes from the freezer only..Then removed the traysand then the 2 panel screws. Defrosted the coils with a hair dryer,removed the 2 screws holding the heater and then unplugged the wires from each side.Installed the new heater and now has been fine for 12 days now..The sensor- I just spliced it in the exact way the old sensor was wired.All seems fine so far. Was alot cheaper to buy the parts and install myself than to pay for 1 service call..

one repair man said I needed freon. sears repair man said my evaporators leaked. and should buy a new fridge. I installed the parts for less than $30.
dried the freezer compartment removed back panel and asst parts. removed screws from evaporator assy and replaced def therm. soldered leads/wing nuts. removed cover from sensor temp and again connected leads. working fine.

Emptied the fridge and freezer. Unplugged it and in so do doing defrosted the freezer coils. Replace the listed parts, for they were right there easy to get at and replace. Between the three of them we had an 80% chance of getting what was wrong. The freezer and the refridgerator are both working just fine. No more warm milk.

For several years, had problem with water accumulating in the bottom of the refrigerator...took out the "custom cool" drawer and assigned my kids the responsibility to dry it out daily after supper (about a fourth of cup of water daily)...the water was condensing and dripping down the left side of the refrigerator... NOT coming from the refregerator evaporator drip pan area. Then the refrigerator and freeezer had erratic cooling...paid 4 grand for this GE stainless steel on the front/sides frig about 5 years ago... then my wife said she wanted a new refrigerator...what the heck...went on to numerous websites and finally decided to do my own "overall"...had nothing to lose except the price of the parts. A helpful web site is the GE technician site at...www.manualinstruction.com/wp-content/uploads/2011/10/ge-sidebyside.pdf. I ordered the four thermisters, a new freezer defroster (the old one was probably OK...the freezer coils were not "iced Up"), and a new defroster thermonmeter. While I was at it, I ordered a new refrigerator evaporator drip pan that was rusting a bit. As per other instructions in this website, just spliced in the new thermisters,used wire twist caps and eletrical tape to seal them. The GE site is a bit more elaborate on the "correct" way to do this. The refrigerator evaporator coil is a bit tricky...see the above ge site...but I just cut the rubber thermister holder down the middle and then tracked the thermister through the holder and stuck it in the block and taped the holder back together...(removed the block first ) and then zip-lined the block back to the coil like it was originally. It was about 3 hours to do everything...and guess what...temp in the freezer is -5...temp in the frig is 36...and NO MORE WATER IN THE BOTTOM OF THE REFRIGERATOR, NO MORE WATER DRIPPING DOWN THE LEFT SIDE OF THE REFRIGERATOR...what will my kids do...I feel like the refrigerator guru now. Wish I had done this several years ago. The parts I ordered came in 3 days. I'm lovin my refrigerator now and my wife is lovin me. It's really easier than I thought it would be...the GE tech website has some "diagnostic" info to isolate different problems... but I just decided to replace "everything" since the parts were not that expensive and it was going to be a "do or die" on getting a new refrigerator.

My problem began with having to replace the auger due to damage (broken blade). Unknown at that time the unit was having a defrost cycle issue. Once auger was repaired, then the motor to auger failed. Once repaired the GE unit then began shutting down without warning. Mother board replaced. All was fine for two weeks then noticed odd performance by ice-maker (chunks of Ice again)and frozen package containers showing signs of dampness and then refreezing. Read through the Parts Select web site to see what other users may have had gone wrong with their GE's and what the parts overview section may reveal for me. Found that the defrost thermo and temp-sensor controlled defrost functions. The parts were cheap, $20.00 for the pair so I replaced them both since they are both located next to one another in the freezer compartment. The repair video furnished on the P/S web was great and very accurate. The entire job only took about an hour. The repair video indicated using wire-nuts and electircal tape Instead, I chose to solder the wires and use shrink-tubing to provide the moisture barrier. PartSelect folks are great not only for their parts pricing but also for the informative videos. The GE works better than ever

went to your website and viewed exploded view to find the sensor( there are two I just picked one to replace for now), pried the cover off carfully and pulled out the sensor. I snipped the wire in the middle leaving plenty to work with. I shortened the wire on the new piece, spliced the wires together and with some 3M rubberized, tape wrapped them up, replaced the sensor back into the cover and snapped in place.
