ZIS420NHB General Electric Refrigerator - Instructions

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.

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 Serial # was HR443071.Maybe this model is out of date for these parts.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

It was easy and fast, like changing a light bulb. The directions were clear and easy to follow. Thank you.

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.

Easy, with included video and instructions

My 14 year old Son

Folowed instructions

exactly as the instructions.......never did see anything about replacing the adapter...therefore i did not

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.

We received the part just a few days after ordering, unscrewed the old filter by hand, and installed the new filter the same way.

I can't tell you how luck I feel after finding your website I ordered the temperature sensor after watching one of your videos on-line and the repair went just as on the video. I pulled the "bad" sensor out, and replaced it with the new one. Keep in mind that this is the first time I ever touch an appliance, needless to say I'm feeling pretty good about that! All in all it took me about 20 minutes to complete my repair and it now has been about 4 days and the refrigerator is working like new again!

replace sensor in refriger.

Remove the shelves then remove the back by removing the two screws at the top of the panel. Locate the temperature sensor on top of the coil. Cut the wires and replace with the new one. Use wire nuts and electrical tape to reconnect the wires.

The problem began when freezer thawed and could not keep food frozen. Initially, I thought the issue was the defrost heater (because I had seen similar symptoms previously and resolved the issue with a new defrost heater)and I replaced that part with a spare that I had puchased previously. The issue was still unresolved and I noticed the evaporator fan was not running in the freezer because it would not turn on when I closed the door. I checked to make sure I could hear the compressor working (and it was)and concluded that the evaporator fan motor was not running. I ordered the part and found a YouTube DIY video on how to replace it. While I was at work, my fiancee took it upon herself to watch the installation video and install the new evaporator fan motor and all is well.

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
