GST20DBMBWW General Electric Refrigerator - Instructions

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.

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

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.

Received parts NEXT DAY! FANTASTIC!

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.

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!

Unbolted the back cover, pulled out old board, replaced with new bored and powered back on. It is working great now.

The replacement part went in quite easily and quickly. The instructions sent with the part was pretty self explanatory. I have also replaced the defroster element, the defrost thermostat and now the main control board. After having done all this the thing is still freezing up. After disassembling the whole freezer section I found yet another temperature sensor (Also known as Thermistor). I'll replace this part next and if it still freezes up you'll be able to find it sitting on the curb. Thrown enough money at this ten year old fridge and a new one will be in order. Thanks Parts Select for reasonably priced parts, the posts to help with the repair and the fast shipping.

First, I removed the cover plate from behind the fridge. Next, I carefully pulled the main board out (four little clips holding it in) and disconnected the plug in wires. I connected the wires to the new board, popped it back in place and replaced the cover. Very easy to do.

Simple; Removed the panel, unplugged the cable connections to the mother board with a rat nosed plier.
Then to remove board you must squeeze closed the 4 plastic retainer clips in each corner, or they can accidentally be pulled off with the board.
Removed the board, re-attached the new board on the clips, then the cable connectors, then the panel.
Plugged in the refrige and it has been silent ever since.
Follow the instructions and anyone can do it.

Simple directions were provided. It took more to clean and vaccuum than the actual repair. Yes I replaced the motherboard in a referigerator. Just keep not of the connectors and were they came off from on the original board. Dont just rip them off because the new board has some different connections. So follow the directions and take your time if your not sure. But really it a cinch. No more whoooo sheeesh and howling noises from the referigerator. Thank goodness.

Replaced evaporator fan motor, and this solved the whistling noise that had developed. Reviewed and followed the removal and installation instruction video as closely as possible. This was very helpful, with a few additions. For the model PS123NGPBBB GE refrigerator/freezer, there were a few differences from the video. There a was an additional cover panel that was positioned vertically at the back of the freezer compartment below the auger motor assembly. It was necessary to remove this cover (4 screws) to gain access to the auger motor cover screws. The unit also has a different light configuration with 2 lights. I found it helpful to remove these light bulbs and the corresponding light fixtures in order to remove the evaporator motor assembly. As mentioned in the video, it was necessary to cut the 4 wires from the wire harness of the new motor, and use butt end connectors to reattach these wires to the corresponding wires in the unit. Total job took between 1 and 2 hours, and the motor change solved the noise problem.

I first bypassed the thermostat by cutting wires and splicing them together. This made no difference. I then saw that the defrost heater glass looked dark and may be burnt out. I replaced thermostat and defrost heater in 15 minutes with the parts from part select that arrived in less than three days. I believe the thermostat was the problem and now freezer works great.

Removed cover exposing defrost heater. Defrosted the cooling system. Removed screws holding defroster, replaced old with new, by way of two quick connect eletrical clips. replaced cover. Pretty easy once I figured our that it was the defroster and not the timer.

First let me remind you my husband is disabled so it was up to me to do the repair. I'm 70 yrs old. I first removed everything from freezer and then removed the back cover removimg 4 screws,then i removed the old defrost unit which held 2 screws replaced with the new one then i had to put cover back in place..then put everything back in freezer and so far its working...Only time will tell.But the part was so reasonable that if if i have to i will get another..but not for a while i'm hoping,

I diagnosed the problem using the guidelines on the website using the refrigerator model number. Refrigerator was warm and freezer had frost buildup on back panel. I followed the instructions in the video and removed the back panel with a screwdriver. The coils were completely covered in ice. I let the ice defrost by itself as this is a spare garage refrigerator and I had the time. Once the ice was melted I was able to remove the defrost heater harness with a screwdriver. The tube was black as described by others. Installation of the new heater harness was easy and the wires didn't need splicing because they were long enough. I also replaced the defrost thermostat as well as the sensors since I had the thing apart anyway. I am a 69-yr old woman DIY-er. Videos were very clear and I was able to save at least the cost of just a repair visit before parts and labor. Fridge has been running great for two weeks now.
