Shunt Sensor

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.

After having replaced the main control board and three thermistors, the fridge was still having difficulting getting cold enough - it wouldn't get colder than 15F / 42 F. Uniform frost on the evaporator coil ruled out a sealed system leak, so the remaining culprits were the either the evaporator fan motor or the compressor.

I read that a failed control board is almost always the fault of a bad evaporator fan motor, so this item was the most likely suspect.

To get to the evaporator fan motor, I had to remove, in this order:

1) Icemaker
2) Auger motor and brackets
3) Icemaker bracket
4) Freezer lights and bulb sockets
5) Evaporator panel
6) Evaporator plenum cover
7) Evaporator fan motor bracket

The greatest difficulty lay in swapping the new fan motor harness. Two pins in the harness connector were used for the evaporator thermistor.

I had to carefully cut through the old connector (using a Dremel) to extract the crimped-on pins for the thermistor, then reuse them on the new connector.

The fridge is now maintaining -5 F / 35 F in the freezer / fresh food sections.

On the PartSelect website, I chose the 'refridgerator is too warm' problem choice. The site sugested replacing the sensors so I purchased them. The drain trough on the refrigerator side was leaking and it and the defrost thermostat were not too expensive so I bought them too.
Once the parts arrived I installed them. I had already disassembled the inside of the freezer. The sensors and thermostat had to be connected electrically. So I cut off the old parts and stripped their wires. (the new parts' wires were already stripped.) I then used wire nuts to connect the new wires to the old and stuffed the wire back into its compartment and installed its cover. The defrost Thermostat has to be clipped to the refrigeration line. So after attaching its wires I had to work it into its place.
I then reassembled the inside of the freezer and let it sit for an hour before turning it back on. Once it was turned on it seemed to work well, but after only 3 or 4 days the coils began freezing over again.

Replaced both temp sensors worked good for 2 days then began freezing food. Looked into it further on line. Found small motorized door broken that controls the cold air from the freezer
