ZISB420DHA General Electric Refrigerator - Instructions

looked at the video you supplied for repair.. that made it so easy to repair the problem. I felt quite confident in myself after the video.The repair went smoothly and the refridgerator wotks super thank you so much Rick

Turned off the breaker to the fridge because I couldn't reach the power plug to unplug it . Use small flat head screwdriver to pop out the piece, disconnected the rubber prong connectors, inserted the new piece into the rubber prongs snapped it back into place. Flipped the breaker back on and prayed it worked. It did and I saved myself $120 service call.

with a small screwdriver push in tabs in upword movement to remove the face cover for the three botons of ice crushed ice and water .
once removed remove four screw to take out the circular door .
solinoid plunger will be atached to the door and it has to screws holding the solinoid .
instolation is the oposit steps of removing the part

I used a mirror to locate the two small plastic tabs located on the underside of the ice dispenser light. I used a small flat blade screwdirver to push the plastic tabs forward to release the ice/water selector unit. I read about someone that did not see the tabs and ended up removing the inside of the freezer door, a two hour task! The ice and water control unit then slides out. remove the four rusty screws holding the dispensert and ice chute, the selenoid isthen easy to see.
Just replace the solenoid if your are having problems, I tried to lube it but to now avail. There is some rust in there so good time to clean up and put new screws in. Be care when removing the plastic lock tab on the circut board it breaks easely. If it does no big deal just make sure the connection is pushed in all the way. test your handy work before buttoning up. The solenoid comes with a new plunger so don't worry about cleaning the old one. The screws do not come with.

First, turn off power - since I did not want to pull the refrigerator out on my wood floor I tripped the circuit breaker to that circuit and opened door to make sure interior light was off (ensuring power was off). This unit has a bottom freezer, I took out all shelves, ice maker and all parts in the way of accessing back of interior of freezer section. Removed back plastic section by removing one screw in middle top of back panel and prying it out. This was a bit difficult as it was in there a bit tight but once the plastic warmed up it pulled out ok. This revealed the compressor section and temp sensor that was attached to the copper coils with of all things - a zip tie! In pictures of this that I looked at on various web sites the sensor was on a metal bracket attached to the coil so it made me wonder if tf the factory took a shortcut? I cut the old sensor wire, stripped the two wires 1/2", and connected them to the new sensor wire with butt connectors, I put some silicone into the ends of the butt connectors to prevent moisture from entering into connectors and wrapped the connection in black electrical tape. I then "attached" the sensor to the coil using a zip tie, put the plastic back piece back on, inserted everything I took out and put power back to refrigerator. It's been 3 days and temp of refrigerator is stable, ice maker not clogging up, and compressor not running all the time! So far so good.

If you have a reverse osmosis system for filtered water system in your home that also feeds the refrigerator, using another water filter in the refrigerator is redundant, so GE makes a Water filter Bypass Cap that allows you to run using the already filtered water without needing to expensive water filter. FIRST - using a phillips screw driver remove the toe kick plate at the bottom front of the refrigerator - two screws - one on each side of the plate that extends the entire width of the refrigerator. SECOND - Locate the water line (should be right in front) and the valve to turn off the water. Turn valve clockwise (right) until completely closed. Then test by attempting to fill a glass with water using the dispenser on the door. If any water continues to come out, continue turning the valve (without forcing it) clockwise until it has been turned as much as possible. If water still comes from dispenser, locate the source of the water line - most likely from under the kitchen sink. There should be another valve under the sink, or simply turn off (turn the cold water valve clockwise) until water cold water completely turned off. Test again as required. THIRD - clear the top right hand back shelf directly under the water filter screwed into the ceiling of the refrigerator in the rear top right side of the refrigerator. Place a small towel under the water filter, and slowly turn the filter 1/4 turn clockwise without using force. Continue turning until the full 1/4 turn is complete and the filter will drop down without pulling. Place the old filter upside down in the sink, thereby allowing the filter to drain any water present in the filter. FOURTH - remove the filter plug from package, notice notches in top of plug that align with gaps in the area where a filter would typically be screwed into the filter location in the ceiling above the top right shelf in the refrigerator. After aligning notches in the bypass plug with gaps in the screw mechanism, carefully turn the bypass plug 1/4 turn counter- clockwise - at which time the bypass plug should be firmly installed. FIFTH - Reverse step SECOND, and turn valve Counter-Clockwise until valve is completely open. Test to ensure no water is leaking from the Bypass Plug. SIXTH - Finally reverse step FIRST by reattaching the toe kick plate using the two phillips screws removed in Step FIRST. NOTE: The Bypass Plug is quite inexpensive, but after adding shipping from Canada - the cost is about the same as purchasing a new filter for the refrigerator. :-(

Replaced flapper valve per website instructions. GE factory technician took two weeks to get here, charged over $100 for the call and told us we needed a new refrigerator door at a cost of over $500 to fix the problem. We sent him packing. After visiting the PartSelect website, the $5.88 PartSelect flapper valve fixed the problem. Amazing.

with a jewelry screwdriver I pried the lock tab in and pulled switch down carefully, the hardest part was that the power wire connector was stuck on good but the pliers and the jewelry screwdriver was its match for a bout 5 minute for one connection a simple pull off prong connection. After the wire connected back to switch it popped back in SNAPP

Took old one out with my fingers. Put new one in with my fingers.

Pop out switch, pull wires, attach wires to new switch and pop back in. Easy smeasy!

Remove control panel.
Remove four screw in control panel bracket.
Remove to bottom screws at bottom of solinid loose top screw.
Replace all screws.

Removed face plate, which holds the circuit board. Removed the next section be removing the 4 screws that hold it in place. Then removed the old solenoid, and replaced it with the new one.

Followed the online video. Unplugged refrigerator, removed trim piece, lifted control board cover, removed 4 screws retaining circuit control board and removed the 3 connectors from the control board. Located flapper and removed by using small flat tip to take tension off flapper connectors. Helper held flash light to illuminate flapper connectors. Reversed procedure. New flapper seals well and cured problems. Circuit board was a bit different than one in video, but still had the 3 connectors. Marked each connector with grease pencil at top edge to ensure correct reconnection. Should note how wires are threaded around circuit board to ensure they are tucked back in correctly in reassembly. Remove trim piece carefully. I broke 2 of the 8 plastic pins that hold trim on. May be due to age of unit as they were brittle. 6 pins still hold trim piece flush.

First tried just replacing flap/spring and mounting. Still did not work so then order a new solenoid with piston that attaches to mounting. That solved problem completely. Corrosion around piston prevented fluid movement of flap. Easy fix after watching video. Saved a bundle I'm sure. Thanks !!!

Remove ice maker and all of it's accessories in order to remove the panel covering the fan. Don't drop the screws!
Unscrew the lower fan bracket. You will see the lower red rubber grommet. Hold fan motor with one hand and push the fan off the shaft and into the compartment above. Then remove the round retainer thing below it by holding it and pulling down on the motor assembly. Install new grommet on upper part. and put it all together.
REMEMBER where the fan is on the shaft. It has about one inch of shaft placement. I put mine so that most of it was above the hole that the fan goes into and about 20 percent showing below the sheet metal.
Also check to see if your fan is damaged. Mine was not.
This refrigerator has been awesome! I have had many issues but have been able to fix all of them for the last 15 years!
