ZIS420NXA General Electric Refrigerator - Instructions

First turn off the power, remove the ice tray, remove the two screws holding the ice maker to the side of the freezer, use the screw driver to gently open the electrical clip for the power cord inside the freezer, remove the complete unit from freezer, bend the old stripper from the holding pin- it is flexible- it will bend, replace the new stripper on the holding pin and bend into the slot to hold it firmly, no water will come out from the fill cup into the freezer, plug in the power cord, mount back to side of freezer, you are done.

Tested the circuits then the inverter and found that to be no good. There was no 277 voltage leaving the inverter. Ordered new and replaced. The frig is now working fine.

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.

Remove rear plate. Remove fan bracket. Replace fan gaskets, blade and motor. Replace bracket. Replace rear plate. Very simple. Fixed the problem.

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 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

I visually inspected the compressor and narrowed down the source of the noise to the freezer area. Then I removed the doors and the screws securing the divider panel. Next I removed the bottom panel of the freezer, the styrofoam insullation panel and the evaporator motor. The motor is mounted between two grommets. I replaced the grommet facing the fan blades. The aluminum reflector below the styrofoam insulation panel had also come loose. I reattached it and reassembled the refrigerator in reverse order. The noise is gone!

I used pliers to pull lightly on the head of the switch, while I inserted a small flat head screw driver into the base of switch and gently worked around the edges to free it from the panel.

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.

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 pulled the refrigerator away from the wall and turned off the water to the refrigerator and unplugged it from the wall. After removing the icebucket from the freezer I located the mounting screws, loosened them, unplugged the electrical connection below the icemaker and carefully removed it from the freezer. I unpacked the replacement icemaker, matched it against the original and attached the electrical connection adapter. Using the slots provided on the new icemaker I placed it over the mounting screws after aligning the water inlet pipe properly. I tightened the mounting screws while maintaining the icemaker in a level position. I plugged in the electrical connector. Then I replaced the icebucket, plugged in the refigerator back into the 110VAC outlet, turned on the water and repositioned the refrigerator in it's normal position.

Replace the motor fan on condenser and clean the condenser

removed freezer door / shelf /ice maker pulled back panel off and removed fan

-Pulled refrigerator out to access back.
-Removed compressed paperboard cover.
-Found compressor running by the feel.
-Removed metal cover to control board.
-Found ~5V coming from control board to inverter (variable frequency drive) board assembly attached to compressor.
-Found ~120 going to inverter board.
-Removed inverter board assembly from compressor.
-Found equal resistance (~7 ohms for mine) at all three contacts of inverter (DC) compressor.
-Ordered inverter assembly, plus one extra and control board for possible future use so not to loose all my food again; I might order a compressor so I have it before price goes up.
-Installed inverter when arrived.
-Used air compressor to blow out accumulated dust on condenser coil.
-Closed up and cleaned up (C^2).
-Fridge cooled and back to proper temperature the next day.
