ZISB420DXC General Electric Refrigerator - Instructions

Actually this was a two part repair of which I purchased both parts. The micro switch Pt # PS296176 and also a double outlet water valve Pt # PS304374 from Parts Select as well.

The difficult part was accessing the area to get to the micro switch.

The trim had to be removed, then the cover.

Then one unplugs the board and removed the face plate which also contains the micro switch.

Once removed the two electrical terminals had to be disconnected, the micro switch installed and terminal reconnected.

Then reverse the removal procedure.

Then on to the double outlet replacement.

Suggest watching the installation video for the replacement although it was really a straight forward repair.

Two things to remember.

1. Unplug the fridge

2. Shut off the water to the dispenser

Overall it was not bad at all.

This was my first attempt at refrigerator repair and it went well.

Good luck on yours.

unscrewed old filter by hand, installed new filter.

Replacing servo was not hard, but did not solve problem. Searched some more and the cure is to remove the light bulb from the dispenser. Seems that old bulbs draw too much current and cause the control panel to fail in sending signal to icemaker motor. Removing the bulb cured this fault and the control panel worked fine.

First, had to use punch tool to pop out electronic face panel. Face unit still connnect via wires. Use painters tape to hold against refrig. Next, Remove ice/water dispenser and also tape to door. This will give you access to solenoid. Remove the 3 screws holding it in place and unplug fsolenoid from Face Panel. Screw new solenoid and place and connnect to Panel. Goood idea is to unplug regrig. while doing this and put a little WD-30 on shaft of solenoid. May want to order new screws, could be rusty, that hold solenoid in place. Sounds a bit complicated but not that bad a job. You'll save over$100 over GE's service.

Called partselect and gave my model number for the frig. I wanted a filter plug because we did not need a frig filter. We have a whole house filter. They looked up the part, took my info, and sent it to me by UPS. It arrived fairly quickly and fit the frig perfectly. I screwed it into place immediately. It was the simplest order I have ever placed and the salesman was very pleasant and proficient. If I have more issues with my frig, I will call partselect again. Just remember to turn off the water before you start.

First I hired a repairman and he said that it was in the unit and would not be worth the expense to fix.

I started to research on the net and this was one possible source. ( evaporator fan). I had to take it apart to verify it. Then put it back together to use until the part came.

The next time went much faster as I did not have to take near as many screws out to access the fan motor. Very Happy to have it working fine again as a new relacement would cost $1200. Thanks much. Ron

No self defrost. Measured heater coil with ohm meter which was OK (not open). Ordered 2 temp sensors (there are 2 in freezer, 2 in fresh food sections). The original and the new all meaured ~150 ohms. Replaced one by one. This did not fix problem. Ordered defrost thermostat. Original measured ~150 ohms - new one was ~100 ohms. Unpluged refridgerator. Removed coil panel (4 nut screws) in freezer and light cover (1 small phillips screw). Locate defrost thermostat clipped to top of coils (orange / pink wires). Cut wires and unclipped thermostat. Stripped insulation off of wires and reconnect using wire nuts. Clipped thermostat back to coils. Ran refridgerator without panel on coils to see if coils frosted up again and listend for fans/compressor to stop ( took hours). Opened freezer and viewed glow of defrost heater. Problem resolved.

Unplugged power cord. Used a small screw driver to release the bottom of the control panel. Pulled it out and unplugged wires, then set it aside. Removed 4 screws from the housing shield and pulled it out. Now the solenoid assembly and related parts are accessable. I removed the solenoid assembly by loosening the top screw and removing the 2 bottom screws. This was the main problem, but I also replaced related parts that were worn or corroded. I also cleaned and disinfected everything in there while I had it apart because it was pretty nasty! Now it works like new.

I followed the instructions found on this website. I removed the control panel by inserting a small Phillips screwdriver in the three holes at its bottom. I used the same screwdriver to pull the dispenser assembly down but could have used a larger one. The microswitch could be seen in the assembly at that point and was easily removed by opening the "fingers" that held it in place. I attempted to pull one of the terminals off without using a pair of needle-nosed pliers and ripped the wires right out of the terminal(I was able to find a replacement at Radio Shack). Low and behold after reinstalling the new part, it did not take care of the problem.

My problem is the water dispenser does work intermittently. When we place the glass in position and hit the lever, the lights in the control panel go off and no water is dispensed. My next guess may be the water valve or the control panel. The icemaker makes ice but I have had problems with it dispensing for nearly a year now.

I had lost the provided bypass filter plug. I decided to replace it with your part.

Your website was very easy to use and the product shipped very promptly. It was great experience. Thanks!

First, I removed all the shelves and the light guard. Second, I removed the nuts that held the fan guard and the freezer back in place (2 just under the fan guard and removed the freezer back. Third, lifted fan guard out of way (being very careful not to crack it..... cold plastic). Fourth, unpugged fan from pug then removed nuts that held fan bracket in place...removed fan. fifth, then removed fan blade and remove fan motor from bracket, removed two wires that went to freezer light (pay attention to where they go) and installed them into the new wireing harness. Sixth, installed fan blade on new motor, bolted new assembly in fan bracket, plugged in and reistalled fan into the freezer, replaced fan guard and freezer back (reverse order of above) and then replaced freezer racks. works beautiful.

I had taken the noise long enough and wanted to get this repaired. I didn't want to pay a repair man hundreds of dollars to do it so i decided to do it myself. I went on to YouTube and found a few videos that showed me how easy it was to do (very helpful).

I wasn't so sure all that noise would come from the Evaporator Fan motor so i ordered it and took the chance. For the small cost, it was worth the try.

All went well accessing the unit and removing the old part. Very fast indeed. However, the snag came when i went to plug in the new part electrical to the existing electrical adapters. The old part had 4 lead connections. The new part had 6. and the wires on the new part were different colors than the existing. I had to use some logic and courage to cut the wires on the new part and rewire the old adapter to this piece. Luckily, i wired everything correctly.

Calling Part Select got me a phone number for the parts manufacturer to help with the splicing but i opted to do it on my own.

The result is i have a noiseless refrigerator again. What should have taken 10 to 15 minutes took half an hour because of the wiring but overall, very easy.

opened refrigerator door located water filter location in right back corner unscrewd 1/2 turn and out it comes without shutting off water it is a snap to do by anyone and shipment was really quick thanks. People do not call a service tech for something this simple even a child tall enough can do it.

remove by hand turning old and replacing new by turning by hand.Lifted out old grill and placed in new one
