ZIS420NXC General Electric Refrigerator - Instructions

Ironically I did this today, as this email request came up asking how it went. I'm not a repairman, I'm a software engineer, and I can't thank this site enough for the step by step videos. With the video to help, this was a breeze, I was nervous as I had to empty all my freezer out onto the living room floor. Once that was done the repair took about 30 minutes. Thank you partselect!!!!! My second time doing business here, and I'll be coming back (well, if something breaks, so let's hope I don't have to).

Replaced secondary inlet valve. Replacing the valve is repetitively simple, just cut the water tubes from the existing valve and insert into the new valve. Hard part is pulling the built-in fridge out of the cabinet space.

follow repair viedo

i followed a video that was on your site, the video couldn't have been easier to follow it was step by step and very easy to follow, i replaced the evaporator fan motor and everything is working fine, i did notice that the evaporator coil was frozen pretty bad when i removed the back freezer panel i am going to check it again in a couple of weeks to make sure i don't have a defrosting problem as of now everything is fine i am hoping it was just the bad fan motor causing the coil to freeze up because of no air movement over the coil

followed you online video and it was easy and simple repair only took about an hour frig is back quiet and working fine thanks also parts come fast

My refrigerator was making a high pitched kind of howling noise. The PartSelect symptom that was closest was “unusual noise” and when I clicked that it said the evaporator fan motor fixes the symptom 32% of the time. Since my freezer fan speed sounded like it was constantly changing I went ahead and bought one which PartSelect delivered promptly. The installation video was great and although my freezer was not identical to the one in the video, the video was still very helpful. The only thing it didn’t say was how to tell if my freezer motor was the one with the thermistor although I suspect that they all are and that PartSelect is simply trying to save us money by showing us how to splice in a motor without a thermistor. Anyway, since I would have had to disassemble the freezer before buying the part to find out for sure, I just bought the one without the thermistor. This just meant I had to splice the new motor in, just like in the video. I think I would have preferred buying the motor with the thermistor even though it was more expensive. In the end my problem is solved so I’m happy. This is the third time that I’ve had to repair this GE refrigerator and PartSelect has been a valuable resource each time.

After replacing the Defrost Thermostat, Defrost Heater Assembly, and the Main Board, I concluded that the problem must be the Defrost Thermistor, which I replaced in less than 10 minutes and it fixed the problem! I cut the wires on the old thermistor and connected the new one after stripping the wires and taped the new connections with electrical wire. Fast and easy repair (the last part anyway ;).

I ordered 3 temperature Sensors Part#PS304103 and viewed the video. Got there, opened the frig. and it looked totally different and no place in any part of this frig. that took these sensors as viewed on the video. Totally baffled why these parts were listed for this frig. there was no place in this frig that would access for these parts. Serial # was HR443071.Maybe this model is out of date for these parts. Trying to find someone who can repair it. Any ideas???Purchased this GE in 2008. Model #is GSS25WSTFSS Thanks, for your help. JIM

1. Removed and tested defrost heater, tests good. 2. Reinstalled defrost heater. 3. Removed and tested defrost over-temperature sensor, tests good. 4. Reinstalled over-temperature sensor using soldering iron, dielectric silicone grease, and heat-shrink tubing. 5. Removed the control printed circuit board and checked for blown fuse's, fuse's are all good. 6. Removed the defrost relay from the printed circuit board using soldering iron, bench tested the relay, it is good. 7. Soldered defrost relay back onto the circuit board, and reinstalled control board. 8. Removed and bench tested evaporator thermistor, the resistance is out of specification, ordered new thermister. 9. Installed new thermistor using soldering iron, dielectric silicone grease, and heat-shrink tubing. 10. Re-assembled refrigerator. 11. Installed temperature monitoring and recording instrumentation for 72 hour test. The defrost cycle is running correctly with a defrost termination temperature of around 90 deg-f. The defrost cycle ran twice while running the 72 hour test. 11. Removed test instrumentation and Put the unit back into service, The thermistor was the culprit. I bought the right part on the first shot, nice.

Had to remove all the covers and fans to expose the condenser, which was difficult as the parts were frozen to it. The styrofoam covering the condenser made it almost impossible to defrost it. Therefore, I ripped the styrofoam off to expose the condenser. Was not really difficult to fix the styrofoam cover using metal tape. Replaced temperature sensor in aluminum block, and used butyl sealant to secure. Had to also re-install parts of ice-ball kit that were not well covered. Lots of parts to keep track of, but anyone could do it.

had to rewire the harness in place in freezer. should have removed door for more room to work . easy job if you have 4 foot arms and a 1 foot chest.

What an awesome site! After putting in my model number and finding the problem I was having, I simply picked the 2 parts that were most likely to solve the problem. I bought a defrost thermostat, and defrost heater. To a high certainty, they would solve my problem. They didn't however! I ended up having to buy a temperature sensor on another order a few weeks later when the problem resurfaced! My own fault. I should have bought it the first time. As others have written: the longest part of the job is defrosting the ice from the coil. One thing I did that I didn't see suggested: plug the drain hole below the coil. I put a couple towels in the bottom of the freezer and ran the hair dryer. Didn't take long. I read that the amount of water created will overflow the pan under the refrigerator, so I plugged the drain hole. Once you clean that mess up, the repair is pretty straight forward. Great site. Even through I had to make two separate purchases, I still saved a lot of money. Thanks!

Very limited working space in this model. Must remove grill and disconnect elect connector on motor. One additiional tool suggested: Extendable rod with magnet on end because you will most likely drop something. First, remove two screws holding motor to metal strap. Tool must be inserted between blades of fan in order to get to the screws and this is the hard part. Fan and motor are removed as one assy and this takes some manuvering. Might have to remove front screw on metal strap to gain more room. I did not attempt to remove fan shroud. My fan was attached to the motor shaft with a metal clip. Spray a good lubricant such as PB Blaster on the shaft, wait a few minutes and press it or tap it out gently. Save misc parts on old motor for reassembly. Your set up may be different so check out everything before starting.

I followed the video provided by PartSelect, very helpful. I had to cut and splice 4 wires. The repair was successful. The replacement part was an exact duplicate of the original. I still notice the same sound but one tenth the volume. I hope the problem does not return. Many thanks to PartSelect for information to identify the problem and prompt shipping of the repair part.

Followed the video instructions with the help of a young man who worked on trailer hitches before and knew how to splice wires. Beware of splicing the wrong fan motor back into the assembly. . . . That happened here and we had to start the splicing all over again with the correct fan motor.
