Removed back wall cover over coil. Defrost all ice with a hair dryer. Cut white wires and replaced Temperature Sensor. It has been working for a week and no trouble at this time. If you have this system on your GE refrigerator do this before replacing the motherboard. I must admit I was thinking that was the trouble. Motherboard was replaced after 5 years old now 5 years later my thinking is this a 5 year problem. So try the Temperature Sensor.
I replaced the three sensors, 2 in the freezer 1 in the refrigerator. This was rated as the most common problem. Did not fix the problem. I then checked the ohms on the new sensors then the old sensors they were all within .5 of each other. So I got smart and went down the list of causes on their list. I emailed partselect and asked what the parts should read. They replied with that information and it turned out to be the voltage converter on the compressor. I ordered the part on friday payed for overnight delivery and it arrived tuesday. This as you can imagine makes me angry. But the part was easy to install and my refrigerator started working right away. I would advise anyone with this problem to start at the top of the problem list use a multi meter check everything on the list and only replace part or parts that don't come up to standards. This will save time and money and hopefully fix the problem the first time as you are not switching out parts and hoping that it solves the problem.
Replaced Defrost Thermostat. Tricky removal of light fixture cover and evaporator cover. Light cover screw removal is not intuiitive and the eveaporator cover tabs are not easy AT ALL to remove.Once they are removed, simply 2 screw removal of rear panel.
Had to unscrew screws holding cooling coils to gain access to thermostat mounted on a coil in rear.
Simkple matter to cut wires, remove old thermostat and splice replacement back on. Found it simpler to re-mount thermostat on top coil greatly simplifying process.(Why didn't they place the original unit in this much more accesible place?) Re-attach coils to rear wall replace rear panel, light fixture cover and evaporator cover.
Refrigerator has been running fine this past week.
1 opened door 2. pryed cover off from cieling 3.cut and stripped wires on 4. sodered wires from old wires to new sensor. 5 insulated conection.6 put cover back on. This did not fix the problem it was the control moduel.
I simply removed the old seal on the refrigerator door and replaced it by just pushing the new gasket seal back into place. It was a very easy repair to do.
I found instructions on the web about how to do this repair, so I ordered the part with confidence. But the instructions simply said "pull out the old switchlight". That was actually somewhat difficult as the clip on the side intended to hold the part in was stubborn. I eventually used a utility to slice off the clip. From that point, it was just a matter of plugging in the new switchlight , which was very simple.
Turned off the breaker to the fridge because I couldn't reach the power plug to unplug it . Use small flat head screwdriver to pop out the piece, disconnected the rubber prong connectors, inserted the new piece into the rubber prongs snapped it back into place. Flipped the breaker back on and prayed it worked. It did and I saved myself $120 service call.
I watched the video online, followed the instructions and within minutes had the part installed. The frig light was working once again! I will say the original switch was very snug and I had to do some very minor scraping of the plastic to get the new part to slide in.
I watched the video online and it said there were three sensors in the refrigerator, two in the freezer and one in the refrigerator. I only ordered one sensor and was going to try the one in the refrigerator first. He said the upper one in the freezer is the most difficult, but is usually the problem. So, I replaced the upper sensor and tried restarting the unit. Everything went well and it fixed the problem.
I followed the onsite video and had no problems. Shut off refrigerator, removed storage trays and bind, removed the rear panel under the light, identified the orange and pink electrical wires and cut them. Spliced the new wires of the thermostat with refrigerator wire and capped them, applied electrical tape to insure no moister makes contact with wires. Replaced rear panel and storage racks and bind. Plugged in the refrigerator and it is operations like new. I was about to purchase a new refrigerator for $ 1,300.00 and the thermostat costed $ 13.00. What a Christmas present!
