ZISB420DXC General Electric Refrigerator - Instructions

Bent the motor bracket down, then using a rat tail file, elongated the holes in the back panel of the refrigerator to secure the fan in the "centered" position. This was a problem that was with the refrig. since it was made. The parts involved were perfect. NO problem at all installing them.

I followed the video for my model refrigerator on parts select. My hint: when returning the back panel of the freezer, it's slightly adjustable left and right to avoid grazing the fan.

The only tricky part was removing the front panel. Releasing the latches required considerable force. The best tool I found was a "jack knife" type Allen wrench set, using the medium size wrench, which fit into the release hole and upward pressure did the trick. The rest of the job was very easy.

Took old one out with my fingers. Put new one in with my fingers.

Unscrewed old bulb, inserted and screwed new bulb into place

Remove control panel.
Remove four screw in control panel bracket.
Remove to bottom screws at bottom of solinid loose top screw.
Replace all screws.

with a philips screw driver and that's all it was that easy

Find a video on youtube. Remove 6 screws. Pull the Styrofoam part up before removing the panel. Unplug and Remove the fan assembly.
You will need a NUT DRIVER to take the bracket off the backing plate.
I ordered the red grommet and the red bumper. You need TWO of the red grommets if that is the problem. My freezer was about 8 years old, and the grommets were worn and compressed, the bumper was not. Replacing these parts DID NOT FIX the problem. I needed a new motor.
I probably disassembled and reassembled this stuff about 7 times before I got all the parts and tools. Each time I had to unload the freezer.

First tried just replacing flap/spring and mounting. Still did not work so then order a new solenoid with piston that attaches to mounting. That solved problem completely. Corrosion around piston prevented fluid movement of flap. Easy fix after watching video. Saved a bundle I'm sure. Thanks !!!

- With a plastic thin putty knife remove the trim panel around the water dispenser. There are plastic clips along each side that just need to be slid inward slightly to release the trim. The thin plastic putty knife worked great for this.
- Remove the electronic panel by pushing the top of the panel down slightly to pull out at the top. The bottom will then come out easily. Remove all electrical connections so the board can be detached completely.
- Unscrew the four screws at the corner of the Dispenser Housing Shield. Before removing, note the position of the wire runs for re-installation.
- Take some pictures of how the old Ice Funnel is attached then remove it and reinstall the new Funnel.
- Make sure wires are in their proper place before screwing the Dispenser Housing Shield back in place with the four screws.
- Connect wires to back of electrical panel and angle the panel into the proper place at the bottom and then pull down slightly to go in the top.
- Reattach the trim by gently pressing the plastic tabs into each slot.

Removed face plate, which holds the circuit board. Removed the next section be removing the 4 screws that hold it in place. Then removed the old solenoid, and replaced it with the new one.

unscrewed old bulb and screwed in new bulb. checked and new bulb works great. less than five minutes to complete.

We had problems with the ice dispenser chute building up frost from condensation freezing due to the flap not closing properly. It would clog up completely and often. I had already replaced the flap and spring years ago but it didn't help much. I Googled this problem for my model and found a video detailing how to check and change the solenoid. Sure enough, the solenoid was completely corroded and crumbled in my hands as I removed it. I ordered the replacement part and made the repair myself. The video was perfect in describing. If your refrigerator is well used as ours is, you'll be shocked by the buildup and cleaning that will be necessary as you make this repair. I ended up taking much more of the dispensing assembly apart so I could clean it with warm soapy bleach water. Be mindful as you disassemble or take photos / videos with your smartphone to help put it back together. It took longer to clean than replace the solenoid. Also, be careful if you have an island or other cabinetry close by. If you have to pull the refrigerator out to unplug it, the handles can chip granite edges or the top corners can scratch wood work. We have cherry cabinets that surround ours. I chipped the edge of the granite when I pulled it out and I scratched the wood as I pushed it back in place. Minor repairs but can save you some frustration. Good luck!

Remove ice maker and all of it's accessories in order to remove the panel covering the fan. Don't drop the screws!
Unscrew the lower fan bracket. You will see the lower red rubber grommet. Hold fan motor with one hand and push the fan off the shaft and into the compartment above. Then remove the round retainer thing below it by holding it and pulling down on the motor assembly. Install new grommet on upper part. and put it all together.
REMEMBER where the fan is on the shaft. It has about one inch of shaft placement. I put mine so that most of it was above the hole that the fan goes into and about 20 percent showing below the sheet metal.
Also check to see if your fan is damaged. Mine was not.
This refrigerator has been awesome! I have had many issues but have been able to fix all of them for the last 15 years!

I followed your video and completely dismantled the refrigerator evaporator motor, fan, brackets, and grommet, I completely cleaned the refrigerator including the cooling coils. I then ordered the evaporator motor ,fan, grommets, lid bumper, and brackets. The order would take a week to arrive. In the meantime I cleaned and reassembled all the old parts, waiting for the new ones to come. Guess what! The refrigerator was quiet as a mouse. I really did not need the new parts, but I kept them anyway just for good luck. Not bad for a refrigerator that's twenty four years old.
