ZISB420DKC General Electric Refrigerator - Instructions

The allan wrench pushes into the holes nder the front control plate and it pops off. Unplug the wires and set aside. Four screws removes the next piece and the "flaper" door is visable.

First I removed the ice tray rack lifting it out of the way to reach the back cover of the fan. Then, the whole back inside panel had to be removed. Two screws removed the fan and bracket from the freezer unit. The missing bumper lid just snapped into place. Replaced everything in reverse order. Pretty easy job.

Replacing was easy. Cleaning took the longest. Order screws with parts, I could not find them at the hardware store. I suggest a coat of oil (3 in one) on the solenoid/piston surfaces. I probably did not have to replace them. The rust was inhibiting the piston movement. Some steel wool and oil would have probably fixed it. If the flap closing starts sounding softer, I'm going to take it apart and clean it first.

Moved stuff out of my way on the top shelf, reached in and turned old filter to remove. Filled new filter with water, lined up and turned to lock in place. Whew, never thought I would get that job done. :-)

First I removed the electrical plug from the back of the freezer that plugs into the icemaker. I then removed the two hex head screws that hold the icemaker to the wall of the freezer and removed the icemaker. I removed the plastic cover, which incidentally protects the gears, by prying it off with a srewdriver. I removed three small nuts(7mm) which holds the internal cam in place. I removed the cam by pulling it off the shaft. Once I got the part from you folks I reversed the procedure that I just mentioned, and put the icemaker back together. It works great. The part with shipping was around $16.00. A new icemaker was roughly $159.00. If I would have called a technician it would have cost around $300.00 to repair.

Ordered new solenoid so the flap would close. That did the trick.

I replaced the original solenoid, which had rusted into one solid piece. OMG how easy was that!

Remove the one screw holding the unit in place, unplug it, slide in the replacement, plug and screw it in.

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.

flapper then bought the spring

There are Great videos on YouTube!!! Turned off power,Removed trim ring, Pushed a philips head screwdriver in one of the holes underneath the electrical panel with the selector push buttons. This releases the electrical panel. There are Three wire sets with plugs. I removed the plugs and took the electrical panel out. Removed four Phillips head screws and pulled out the big paddle switch. This then exposes the flapper. Replaced flapper with new one and reassembled everything. When I had everything apart, I cleaned with window cleaner. It was pretty moldy from the water leaking. Turned power back on and tested everything to make sure I didn't mess anything up. Works great

Took the old filter out and put the new one in.
Easy Breezy!!

I followed they instructions from the other "do it your selfers" but only replaced the solenoid. This was the cause. Rust was keeping solenoid plunger from moving and this held the flapper door open. Very easy to repair!

Unscrewed old cartridge, ordered new cartridge, installed new cartridge by following very simple instructions. Took only one day for part to arrive from PartSelect although I paid for cheapest shipping, which was "ground." I was amazed!

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.
