GST20DBPCCC General Electric Refrigerator - Instructions

Diagnosis of symptoms was condenser fan not running, due to faulty main board.

First: removed the cover over the main board, which was too hot to touch. Bad design flaw, no ventilation for the board, which I believe made it fail. We got another year of service with the cover removed.

Second: after reading people's experiences here, ordered the board and popped it in. (Note: needed a pliers to compress each of the 4 plastic studs holding the board in.) Works like a champ.

Third: did NOT replace the cover. At our altitude the air can't conduct enough heat to prevent cooking the board. Need to allow circulation.

Removed cover plate on rear of unit - 3 screws

Removed connectors and ground wire

Removed board (use needle-nose pliers to compress plastic mountig posts)

Replaced board, inserted connectors, attached ground wire, put cover on

Everything worked properly

I must admit - I thought I'd attempt to do this repair and end up calling a service guy to finish it. I'm not mechanically inclined AT ALL but thought I'd give it a shot after reading others experiences. I'm glad I did. The fix was easy, but there was initial anxiety while reading the instructions that came with the part - as they mentioned the possible need to cut some wires. Fortunately that was not necessary..... Removed three screws from the rear plate to expose the part needing to be replaced. Remove the fittings from the old board (needed plyers to do that - be gentle), take the old board out by using needle nose pliers to squeeze the white plastic tabs and pull the board free. Reconnect fittings to new board and you are done. Works better now than ever - obviously the old board had an issue that GE should have recalled, as many others had the same problem.

Pulled out the fridge and unplugged electric cord. Took off the back lower right side panel. Unplugged all the connectors and removed the motherboard. Replaced the motherboard and reconnected connectors. Replaced the panel and plugged it in. Works great!

The control board and access panel are on the back of the refrigerator, so you will need to roll/slide the refrigerator away from the wall to gain access to the panel. Be careful not kink the water line if you have an ice maker connection.
Unplug the power cord from power outlet on the wall.
On this model the control board is located behind a rectangular panel that is about 8" x 10". The panel is about 3 feet above the floor on the left side (as viewed looking at the back of the refrigerator).
Using a Phillips (cross point) screwdriver, remove the screws and the access panel cover. Look closely at the control circuit board and you will see 4 small white plastic protrusions sticking through the board -- these are the plastic posts that hold the board in place. There is a small tab that locks the board to the plastic mounting post. Use your needle nose pliers (or other small pliers) to compress the small tab on the post; and while squeezing, pull on the control board until it releases from the post/clip. Repeat this for each of the four posts and the board will now be free from the mounts.
Look at the plugs that connect the wires to the board and note the orientation of each plug. Each plug is a different size, so they will only fit into the socket of the correct size. On my refrigerator, there is one plug that is not connected to the board and is hanging loose, so don't get confused when connecting plugs to the new board - this one remains unconnected.
Firmly pull each plug from its socket on the board -- try not to pull by the wires. If you have a stubborn plug, grab it with your pliers and pull it out. There is a green ground wire connected by a screw into the refrigerator cabinet. Remove this screw and ground wire. (Note: on some models the green ground wire is fastened with a screw that holds the cover in place - just be sure to reconnect the wire when replacing the cover).
Insert all of the plugs into the new board -- be sure they are seated firmly. Reinstall the ground wire. Place the board over the plastic posts and push until the tab locks the board in place. Replace the cover.
On the sheet that comes with the refrigerator they instruct you to remove the lower panel on the refrigerator that covers the compressor motor compartment. They instruct you to look at the power cord connection to the compressor and to locate a green wire from a capacitor. If your power cord does not have a capacitor exactly like the one pictured, there is no need to proceed on this step. Replace the lower panel. If it does have a capacitor as illustrated, follow those instructions and then replace the panel.

Now plug in the power cord to the wall power outlet. Before pushing the refrigerator back into place you want to make sure it is operating properly. To make sure that there is no "Glitch" during start up, I suggest that you set the temperature control inside of the refrigerator to "OFF" and wait about 3 minutes. After 3 minutes, set the control to the desired temperature (about 37 Deg for Refrigerator and 0 Deg for the Freezer).
If the refrigerator is running, you are finished. Being careful not to kink the water line, push the refrigerator back into place.

I removed the board, unplugged all the sockets, took the new board, plugged in all the sockets, and replaced the new board into the refrigerator. I was to applaud this business. I was first able to diagnose the problem by finding this site, then one of the customers explained how to fix the problem ourselves. It save us at least $100. The $25 overnight shipping fee was well worth it. We could have lost $100's of dollars worth of food.

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.

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 ordered two switches, replaced both with a knife in 10 minutes. Interior light works, thanks.

Unplugged unit.. Removed control board cover.. Removed all plugs from control board then removed board its self.. Replaced in reverse order.. Unit is working as new..

I watched the video provided by PartSelect twice, then proceeded with the removal and installation. It took me 40 minutes from start to finish. Piece of Cake. Everything works fine now.

Turned the power of to the fridge took the food out of the freezer put in the fridge took out all the shelves and took off the panel to get to the coils. I used a hair dryer and a shop vac to defrost the coils used the shop vac to suck up the water as the ice melted also put some paper towel in the drip tube so the water would not go to the drip pan. Took off old defrost heater which was a single heater the new on was a double heater fished out the blue wire from the left side of compartment and ran it down the right side plugged both wires into the heater mounted it into place and put everything back. Turned on fridge and it has been working fine ever since. Thanks for the last person that did this I read his review and it really was that easy
Thanks Jerry

Great Service! Received the part the NEXT DAY!

We originally called a service technician. He came the next day and said the mother board was no good. He order a new one and replaced it a week later. Total part & labor cost: $185.00 (Remember we're without a working refrigerator the whole time the part is on order)
Two days later the freezer is doing the same thing. We call the tech again and he seems confused and says it could be the heating element, he'll order one at no charge and replace it for us free. He never comes back with the part and does not answer our 2 dozen phone calls. I checked the element myself and saw that the tube had been scorched, like a burnt out light bulb. Searched for parts on internet and found this great site. "Partselect.com"
REPAIR:
Refrigerator had been unplugged for a few days to defrost ice build up in freezer. First, I removed the shelves from freezer compartment, removed the back panel and removed screws holding heater element in place, I unplugged the two electrical leads and plugged in new part. AS EASY AS THAT !!!!! I reinstalled the screws to hold the element, installed the back panel and replaced the freezer shelves. I plugged the refrigerator back in and within hours the freezer started making ice again. It's been about 3 weeks and we have not had a problem since.
Fantastic Service and instructions and Inexpensive !!!! I will use this site again, if needed, and will recommemd to anyone who needs parts.

follow the easy instructions replace 3 temperature sensors cut the wires and crimp them with new sensor and it works like new

The back panel was unscrewed, we read the directions with the circuit board and followed them. It was very easy to unplug the old faulty unit and plug in the new replacement part. It was done in 4 minutes flat. Very easy to do yourselves!
