ZISS420NXASS General Electric Refrigerator - Instructions

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.

-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.

Replace the motor fan on condenser and clean the condenser

My son did it , and showed me what he did when he was finished.

Nothing to tell it was just a replacement part that the old part was removed and the new one inserted. Works like a dream Thanks

just had to unscrew old one put the new one in

I ordered two switches, replaced both with a knife in 10 minutes. Interior light works, thanks.

The icemaker arm disconnected from the metal frame. This caused the icemaker to cycle and the heater to come on and stay on until the plastic parts melted causing a mess and stink. This action melted the ice and then the water fell through the frozen items in the freezer and refreezed in the lower portion. OK, I remover the dead icemaker and tossed it away. I installed the new icemaker and the wiring harness didn't fit right (way to long). I retrieved the old icemaker and removed the wiring harness from it. I removerd the new ice maker and installed the old wiring harness to the new icemaker. I then installed the new icemaker, plugged it in and turned on the power. No water, I ordered the dual solenoid water valve, installed it with difficulty (another story) the turned on the power. I reinstalled the ice bin and found it didn't fit. The icemaker was to low and couldn't be adjusted, 1/4" higher would have been great. I shoved in the bin anyway, I was out of ice for my scotch, and it started making ice.

Replaced icemaker assembly. Only 3 Phillips screws to remove the old assembly. Pretty much an exact swap. Was easy to replace but the connecting cable on the new replacement assembly wasn't very easy to make fit. Had to force it into a location that would be out of the way and allow everything to operate properly. That connecting cable should be more flexible and adapt to the fridge a little more friendly.

I found instructions on the web about how to do this repair, so I ordered the part with confidence. But the instructions simply said "pull out the old switchlight". That was actually somewhat difficult as the clip on the side intended to hold the part in was stubborn. I eventually used a utility to slice off the clip. From that point, it was just a matter of plugging in the new switchlight , which was very simple.

1 opened door 2. pryed cover off from cieling 3.cut and stripped wires on 4. sodered wires from old wires to new sensor. 5 insulated conection.6 put cover back on. This did not fix the problem it was the control moduel.

Did the repair just as the instruction said, once I read it. The part I didn't read was that if the plug was under the ice maker, you had to take the wire out of the clip on the side. So, had to dismount ice maker, unclip wire, remount maker, plug it in. Still under 30 minutes. Thank you.

Installation could not have been easier!

I watched the video online and it said there were three sensors in the refrigerator, two in the freezer and one in the refrigerator. I only ordered one sensor and was going to try the one in the refrigerator first. He said the upper one in the freezer is the most difficult, but is usually the problem. So, I replaced the upper sensor and tried restarting the unit. Everything went well and it fixed the problem.

Pulled ice box away from wall. Took lower cardboard cover off. Shut water line off. Got my volt meter and checked the current going from the wall to the plug in at the inverter (input side), and I had the required 115 volts. Then I unplugged the connection going to the compressor (not the plug at the compressor which you cannot see until you unbolt the inverter) but the output connection side that goes to compressor. I checked the voltage and had about 13 volts not the required 115 volts. Therefore, I came to the conclusion that the inverter was bad. I ordered one from Partselect and they shipped it right away. I installed it and the ice box is back up to running order.
