ZIS420NNDII General Electric Refrigerator - Instructions

Located temperature sensor on condenser in the freezer section( as per instructional video ). Cut off bad sensor with wire cutter then soldered on the new sensor and sealed with electrical shrink wrap.

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.

Folowed instructions

I just unscrewed filter and screwed in filter bypass

none required

Easy, with included video and instructions

Unplugged the refrigerator first....then on the inside of the fridge, I popped the temp sensor cover off (upper LH side) and exposed the old sensor. I snipped off the old sensor about 3" down from the end and connected the new sensor (which I trimmed down to about 3" long) with some heat shrink wire nuts/connectors. Let the fridge run for a day or so and confirmed the problem was solved! Oh yeah, there was no way to tell the 2 wires apart (power vs. ground) on the sensor. However there was a manufacturer's stamp on the wires. So note the orientation of the text and mark one of the wires with a sharpie on both the old and new sensor before trimming. This will give you a reference for which wires to connect when adding the new sensor to the old wires.

Temp. Sensor was under an egg shaped cover on the left side wall in the refrigerator. Remove the cover, cut the two wires to the old sensor and remove it. Connect the new sensor to the two wires using butt connectors. Replace cover and done.

as per video- follow all of the videos and u r going to save a lot of money tx partselect im glad I found u guys ps only order from partselect.com they only ship the correct parts remember look at the video select the symptom and buy as per video tx again problemsolved

The repair is a snap, you can watch the video and it will put you on the right path. My story is more about the service that Part Select gave me. I used a small box fan on low as a temporary fix. My model number was worn off from the box wine we store in that particular place. So I ordered the part based on looks, well it was wrong. Called Part Select and we talked, the nice lady on the other end said OH it must be this fan motor. Send us back that one, and I'll get this out too you. I'll credit your account for $7.99, and it cost me $8.99 to ship back the wrong part. Wow, the next day I received the new motor. They sent it overnight! I thought it would be 5-6 days! Unbelievable. I will use this company for any, and all my repairs.

no brainer,watched the video,worst thing was to thaw the freezer,it was realy frosted,works like new,very happy thank you.

followed part select video instructions

luckly i have a bit of experience in refrigeration im an hvac technician by trade. this repair was a bit tricky in that i did not know at first if it was a Temperature Sensor issue or the main control board. I had tested the defrost termination thermostat and the defrost heater and as i suspected they were ok. Next i wanted to test the thermistors (temp sensors) it is hard to find technical data on these fridges. I needed to test the thermistors resistance @ a certian temperature to ensure they were working properly but where do u get such data? I also wanted to know some information about the logic programmed into the board (i.e when do you initiate defrost etc. . .). I had no such luck so i figured since i tested the defrost heater and thermostat and they were ok and all of the evap fans and such were working i'd order a circuit board and new thermistors. Got the CORRECT PARTS from this site in 2 business days and my fridge is working great! changing the parts was really easy, figuring out which parts to change was the only difficult thing about this job.

I have a GE Profile French door refrig. It's only about 4 yrs old and the defroster stopped working. I read the other repair stories and was able to narrow it down to either the temp sensor, defrost timer, or main board. The refrig section was up to about 47 degrees and freezer was around 25. I could tell it was trying to cool but couldn't. So I tried the temp sensor first. I cut and spliced the new sensor on the outlet of the Evap. Coil and it took about 15 mins. Turned refrig back on and waited. The coil started to ice over after about 5 hrs I left the back panel off so I could see if and when then heater kicked on. After about 8 hrs I looked in and saw a faint glow and water trickling down and running out the drain. Turned out the sensor was bad and wasn't telling the main board it needed to defrost. I would try the sensor if you are having the same issues before spending a lot of money on the main board, defrost heater and or timer.

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
