ZISB420DHA General Electric Refrigerator - Instructions

Replaced dispenser door flapper by following the do it yourself video in this site. It was really easy. Just be careful when removing the dispenser black bezel. I broke one of the little tabs when taking it off.

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.

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.

Removed escutcheon, removed control panel, remover and replaced flapper, spring and crank. Followed the instruction exactly. Although I hope this fixes the frosting problem, I did not see anything wrong with the parts I removed. I hope this fixes the problem,

Followed the online video. Unplugged refrigerator, removed trim piece, lifted control board cover, removed 4 screws retaining circuit control board and removed the 3 connectors from the control board. Located flapper and removed by using small flat tip to take tension off flapper connectors. Helper held flash light to illuminate flapper connectors. Reversed procedure. New flapper seals well and cured problems. Circuit board was a bit different than one in video, but still had the 3 connectors. Marked each connector with grease pencil at top edge to ensure correct reconnection. Should note how wires are threaded around circuit board to ensure they are tucked back in correctly in reassembly. Remove trim piece carefully. I broke 2 of the 8 plastic pins that hold trim on. May be due to age of unit as they were brittle. 6 pins still hold trim piece flush.

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 !!!

flapper then bought the spring

Researched on internet/you tube; ordered part, and did the repair. Easy to do and saved the cost of a service call.

Replaced Temperature Sensor and now it is getting cold.

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

Totally followed the instructions of the video that came with the sensor. Unplugged the the fridge, defrosted the freezer. Cut off the main sensor that usually is the one that goes out. Installed the the new sensor with new wire terminals, crimped them and covered with electrical tape. Fridge works like a charm. Partsselect is excellent. Saved me a few hundred dollars versus having a GE Tech come and do it.

I searched the site, found the part - solenoid, watched the "how to" video and the repair was a snap. Saved myself tons of money versus having a repair person come over. I do have an older model and needed to prop the front cover panel off with a screwdriver (just under the covering) saw this on a posting from another individual, thanks for the heads up.

Followed the on line video. Clear, concise & easy. Thanks.

Replace the flapper and this solved it. The video provided was excellent and allowed me to do this repair myself.

I followed the video provided, and followed the advice of bill from cleveland hts. ohio, and did not have to remove the trim to access everything. The video made it so simple, a monkey could have learned how in 5 minutes. Thank you very much for all the help on this website. I will recommend it to all.
