ZISB420DHA General Electric Refrigerator - Instructions

Used the instruction provide by Part Select, which are easy to follow.
When it came to replacing the Solenoid, the two bottom screws were easy to remove, The third screw (located on the top) needed lo be loosened, That screw was very difficult to remove because it was rusted, and I had to replace it.
I suggest that a spare screw should be supplied wit the solenoid.

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.

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!

Opened, discovered not flapper but more complicated

Fairly simple fix. You must first uplug refrigerator, then take off the inside freeze door panel, approx. 25 screws. Then you must take out the trap door assembly approx. 6 six screws. Pop off the LED panel, requires the use of a flat blade screw driver to pop it off. Remove solenold by removing 3 screws, replace with new solenold.

I removed the top vent and unplugged the ice machine ,took the back cover off the freezer.Removed the old fan which was pretty easy(unplugged it after I took the housing out for easy access) I plugged the new fan in and put everything back in the order I took off, and yada yada yada we have cooling.

removed the control panel ,using a paper clip, removed five screws, disconected wire connector, and removed the solenoid. reversed procedure to reassemble. ordered the part one day and received it the next day. Thank you for the prompt response.

I followed the instructions on a posted desctiption. It workded perfectly. Replacing the inner door panel was not as difficult as described. Just start the process with the screws in the middle of the door. Those two screw holes were not slots. All of the remaining screw holes had slots. I installed all of the door screws before tightening any. I workded right the first time.

I started out replacing a bad thermostat, no problem,
when I hooked up the water, I found that the water resovior had a leak.
I replaced the resovior, easy fix, but I had to buy two 5/16 brass couplers.
then I found that the box would not get below 10 degrees, and the suction pressure was very low.
I figured that the fan motor was burned out, so I opened up the access covers, the fan motor was hanging there with broken mounts, so I replaced the motor, and repaired the mount.
Everything works great now, The parts shiping was very fast, I was impressed.
I thought I was going to get away without fixing everyones
HVAC problems when I retired.
Friends and family still remember that you are the HVAC man.

I have not yet done the repair. After watching this repair video two problems came to mind. First I only ordered one grommet not knowing that there were two (or more I don't yet know). The second problem is that this video must be for a fridge from like the 1940, but it looks NOTHING like mine from 2008. The manual shows a bazillion parts and frankly I'm just a wee bit afraid to get started, and I am generally very handy, buuuttttttttt I don't know about this one

Remove front cover did not remove wires remove ice and water unit took off flapper put new one on 5 minutes back together

This was so easy I think it took me 2 minutes. I am not very mechanically inclined but that didn't matter! Works perfect thank you!

I removed the door cover plate and disconnected the circuit board, then four screws. The part was corroded in place. Upon removing three screws and cleaning the surface, the new part was an exact fit, replaced it and everything works like new.

Pop off the control board for the ice selector/water. Remove power / signal connections. remove four phillips screws, Remove plastic hopper. Pop off Ice door gasket, pop in new one and put back together. If you fridge was sounding like it was speeding up and slowing down, this will correct this problem as well.

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,
