ZISB420DXB General Electric Refrigerator - Instructions

The first sign of trouble was when the water dispenser would continue to come out after you let up on the button. Then water and ice stopped. Changed the secondary inlet value and the main water valve, as well as a 1/4" water line running to the freezer (it was cracked). Water is working. Ice maker is working better than ever. New life for an aged refrige.

Remove back panel on bottom of fridge to access compressor area. Remove screws from water solenoid and water valve and push to the side so the side of the compressor can be accessed. Then locate the inverter box. You will find a Phillips head screw on the bottom of the inverter. This is the only screw that hold the inverter in place. Remove the screw and tilt the inverter box forward away from the compressor, then lift the box out of the the holder. You may have to wiggle it a bit to get it out. Remove the plug that attaches to the compressor and then with the power on check your voltage coming to the compressor. It should read 120 volt. If it doesn’t your inverter is bad. Remove the other plug on the inverter box and pull the box out.
Reinstall the unit in reverse order. Use the appropriate jumper to plug into the wire connection going to box and then plug it into the connection off the fridge.
Once everything is reinstalled and before you put the back panel on plug your refrigerator back in and you should be able to hear the compressor working or feel the top of it to make sure. If it’s working you are good and can reinstall the back panel.
It will take 4-5 hours to come back to temp if it’s been off for any length of time.

Pretty easy to repair. Only took a few minutes.

Your video shows how to make the necessary repairs. Solenoid was the main issue, other parts were replaced to bring assembly to "like new" condition. Over kill but thats how I fix things. All and all a very easy fix. Thanks for the info and parts.

Removed the plastic frame by pushing to the inside (all 4 sides), removed touch pad by sliding it to my right and disconnected the wires. Removed the four screws that hold the dispensing unit and replaced broken parts. Please note that I also replaced the funnel. Total cost of repair for DIY $30.00, savings by avoiding repair man, priceless.

Ordered the replacement parts-both water valves, printed the schmatic, then removed and replaced both parts. Was fairly straight forward, rmeember to unplg the fridge before you start. Problem solved, should be good for another 10 yrs.
Hard water prob caused the corrosion. Also replaced the water hose while I was back there, water tastes 100% better.

I found that I did not have the strength to stretch the new spring enough to install it initially. Using a 1/8 or 5/32 inch allen wrench I removed the pivot for the arm that the spring applies tension to. This allowed the spring to be easily attached to the hole in the arm and to the post in the bottom of the refridgerator. I then used a small pliers to grab the arm in front of its pivot hole and pull it against the spring into position to replace the pivot. Replacing the filter was surprisingly easy. I turned the water supply valve off under the sink and easily unscrewed the old filter (about a quarter turn). I filled the new filter with water and srewed in in. No wrenches required. I turned the water back on under the sink and everything works great!

I tried to quite the noisey evap motor with special liquid motor grease from Radio Shack. It did not work, so I ordered the evap motor. My freezer motor was wired slightly different than the motor I received. The replacement motor had a male plug attached to the four wires, the original motor was different, so I cut the wires and spliced them into the original freezer wires (colors were the same). Remounted motor. Works great, and no more groaning motor

Ordered the icemaker replacement. unplugged the unit, followed the simple instructions and got it done in less than 30 minutes. It did take a LONG time to start making ice. But it's working now.

I took the part out of the package and placed it in the recessed water dispenser/ice maker cavity. Done!

Was concerned that new icemaker was quite a bit different than the one we were replacing. Called GE to confirm it was correct.

Went ahead and installed the unit, using the supplied electric cable adapter.

A little difficult to deal with the extra cable, but everything worked OK and it's making ice normally.

I ordered the wrong part, the ice maker assembly, because your diagram was not marked properly. I returned the part and you credited my account. Thanks. Ordered the new bucket. It worked fine. Now I have ice and crushed Ice whenever I want. Thanks.

p.s. I didnt use any tools, but to satisfy you I select nut driver.

several times I had to remove the ice maker door solenoid due to it sticking. I ordered a new one from parts select. Problem solved!!!

I bought a Flapper replacement part from Parts Select. I installed it following their very complete on-line video directions. Their complete and easy to follow directions made my job very easy, and the work was completed without any problems and just as good as if it were done by a professional repair person. I am proud of my work, it couldn't have been done without their video insructions. Also I got delivery of the part within two days of my order. I will alway look for Parts Select any time I need an applicance repaired. Thanks to Parts Select!

Removed front panel (using small screw driver) by popping it out, disconnected wire from solenoid, removed solenoid which was rusted, 3 small philip head screws held it in place insereted new solenoid,connected wire snapped front panel back in. Clapper valve closes tightly and no frost in frezzer, saved my self a bunch of money.
