ZISB420DKB General Electric Refrigerator - Instructions

after finding the video describing the same problem, i gave it a shot. Major problem was figuring out how to take outside trim off of the ice/water dispenser. Everything i tried did not work like the videos i had seen. Looking thru some of the posted blogs i found another way to get behind the control panel without even taking off the trim piece. i pressed a 1/8th allen wrench into the two outer holes on the bottom of the control panel which released the panel to pull out from the bottom. after that it was simple to release the three plugs from the circuit board and remove the control panel. 4 phi lips screws later the ice chute comes straight out revealing the flapper door which is held in by 2 more screws. once that assembly is out the solenoid is held by three more screws. there was nothing difficult at all about this repair once the secret was out about the first step about the three holes (use only the outer two) in the bottom of the control panel

Noticed the problem in November 2009. Replaced Hi Limit Sesor for Defrost thinking it was the freezor temperature sensor. Did not fix the problem. Replaced Motherboard. Did not fix the problem. Called Sears Repair. They mis-diagnosed the problem and told me it was the sealed system. I doubted them and sent them home. Replaced the correct freezer temperature sensor that connects to the motherboard. FIXED.
Removed a panel, cut two wires, soldered and insulated two wries, reinstalled panel.

unscrewed old filter by hand, installed new filter.

Called partselect and gave my model number for the frig. I wanted a filter plug because we did not need a frig filter. We have a whole house filter. They looked up the part, took my info, and sent it to me by UPS. It arrived fairly quickly and fit the frig perfectly. I screwed it into place immediately. It was the simplest order I have ever placed and the salesman was very pleasant and proficient. If I have more issues with my frig, I will call partselect again. Just remember to turn off the water before you start.

The repair is easy, just pop the grill off around the ice and water door, then there are 4 screwws to take out so the touch pad can be moved out of the way to unsnap the old door assm. and snap in the new one and wait about a year and a hald to order another one!!!!!

First I hired a repairman and he said that it was in the unit and would not be worth the expense to fix.

I started to research on the net and this was one possible source. ( evaporator fan). I had to take it apart to verify it. Then put it back together to use until the part came.

The next time went much faster as I did not have to take near as many screws out to access the fan motor. Very Happy to have it working fine again as a new relacement would cost $1200. Thanks much. Ron

No self defrost. Measured heater coil with ohm meter which was OK (not open). Ordered 2 temp sensors (there are 2 in freezer, 2 in fresh food sections). The original and the new all meaured ~150 ohms. Replaced one by one. This did not fix problem. Ordered defrost thermostat. Original measured ~150 ohms - new one was ~100 ohms. Unpluged refridgerator. Removed coil panel (4 nut screws) in freezer and light cover (1 small phillips screw). Locate defrost thermostat clipped to top of coils (orange / pink wires). Cut wires and unclipped thermostat. Stripped insulation off of wires and reconnect using wire nuts. Clipped thermostat back to coils. Ran refridgerator without panel on coils to see if coils frosted up again and listend for fans/compressor to stop ( took hours). Opened freezer and viewed glow of defrost heater. Problem resolved.

I had lost the provided bypass filter plug. I decided to replace it with your part.

Followed previous instructions from a previous post. Inserted small screwdriver in the 2 outer holes up under the face plate to remove it then removed 4 screws holding the inner assembly which allowed access to the flapper assembly. Replaced it and reassembled everything. Problem solved

Your website was very easy to use and the product shipped very promptly. It was great experience. Thanks!

Removed the front panel on the door that has the ice maker controls. Removed the screws and parts. Reassembled the parts and it works better than new. Ice door closes firmly and holds tight.

First, I removed all the shelves and the light guard. Second, I removed the nuts that held the fan guard and the freezer back in place (2 just under the fan guard and removed the freezer back. Third, lifted fan guard out of way (being very careful not to crack it..... cold plastic). Fourth, unpugged fan from pug then removed nuts that held fan bracket in place...removed fan. fifth, then removed fan blade and remove fan motor from bracket, removed two wires that went to freezer light (pay attention to where they go) and installed them into the new wireing harness. Sixth, installed fan blade on new motor, bolted new assembly in fan bracket, plugged in and reistalled fan into the freezer, replaced fan guard and freezer back (reverse order of above) and then replaced freezer racks. works beautiful.

I removed the screws for the inner door and removed inner lining. Then took out the ice dispenser in the door. Took off control panel on the front of the ice panel. Removed the rusted parts and put in new parts. Put all parts back the way it came apart. In retrospect.... I could have possibly replaced the parts from the front panel but by taking apart the door...I had to thaw out the inner panel and insulation with in the door.

I had taken the noise long enough and wanted to get this repaired. I didn't want to pay a repair man hundreds of dollars to do it so i decided to do it myself. I went on to YouTube and found a few videos that showed me how easy it was to do (very helpful).

I wasn't so sure all that noise would come from the Evaporator Fan motor so i ordered it and took the chance. For the small cost, it was worth the try.

All went well accessing the unit and removing the old part. Very fast indeed. However, the snag came when i went to plug in the new part electrical to the existing electrical adapters. The old part had 4 lead connections. The new part had 6. and the wires on the new part were different colors than the existing. I had to use some logic and courage to cut the wires on the new part and rewire the old adapter to this piece. Luckily, i wired everything correctly.

Calling Part Select got me a phone number for the parts manufacturer to help with the splicing but i opted to do it on my own.

The result is i have a noiseless refrigerator again. What should have taken 10 to 15 minutes took half an hour because of the wiring but overall, very easy.

Part arrived very fast as ordered..need to pry old switch out from top..use care to push the retainer down..after old switch was 1/2 out, I used a putty knife for better leveridge.Remove wire connector...after plugging in the wire connector to the replacement switch, make sure the switch is properly positioned so the switch will depress when door shuts.
