ZISP420DXCSS General Electric Refrigerator - Instructions

Used a YouTube video with step by step directions, this made the repair very easy.

I watched the video online and it said there were three sensors in the refrigerator, two in the freezer and one in the refrigerator. I only ordered one sensor and was going to try the one in the refrigerator first. He said the upper one in the freezer is the most difficult, but is usually the problem. So, I replaced the upper sensor and tried restarting the unit. Everything went well and it fixed the problem.

Changing out solenoid was very easy, but you don't have to remove trim ring and it didn't fix my problem. Turns out a relay fell out of its holder in the piece you have after removing the 4 screws per the video.

Replaced evaporator fan motor, and this solved the whistling noise that had developed. Reviewed and followed the removal and installation instruction video as closely as possible. This was very helpful, with a few additions. For the model PS123NGPBBB GE refrigerator/freezer, there were a few differences from the video. There a was an additional cover panel that was positioned vertically at the back of the freezer compartment below the auger motor assembly. It was necessary to remove this cover (4 screws) to gain access to the auger motor cover screws. The unit also has a different light configuration with 2 lights. I found it helpful to remove these light bulbs and the corresponding light fixtures in order to remove the evaporator motor assembly. As mentioned in the video, it was necessary to cut the 4 wires from the wire harness of the new motor, and use butt end connectors to reattach these wires to the corresponding wires in the unit. Total job took between 1 and 2 hours, and the motor change solved the noise problem.

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. :-(

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.

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.

I watched the video online, followed the instructions and within minutes had the part installed. The frig light was working once again! I will say the original switch was very snug and I had to do some very minor scraping of the plastic to get the new part to slide in.

I applied heat to the area with a hair drier. Used a little too much heat and deformed the ice funnel which also controls the water spigot. Ordered a new ice funnel from PartSelect. Part arrived in about a week and included a schematic of the mechanism which made disassembly and reassembly very easy. In a short time everything was working like new.

remove the front of were the ice and water comes out
then un scerw 4 scerw and the solenoid slides out unhook the wires and put the new one in

remove old bulb by screwing it out/install new bulb by screwing it in.

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 I removed the ice tray rack lifting it out of the way to reach the back cover of the fan. Then, the whole back inside panel had to be removed. Two screws removed the fan and bracket from the freezer unit. The missing bumper lid just snapped into place. Replaced everything in reverse order. Pretty easy job.

Take the face (the part with the buttons on the outside) off, disconnect wired connectors (three), take the screws out of the part behind that (4), and then find the solenoid value (on the right). It's attached with three screws. Mine was rusted beyond belief. I knew this was the problem, ordered a new solenoid valve, put it back in place with three screws (use new screws that fit, not the old rusty ones if possible). When testing, make sure you give the flap a couple of seconds to close. There is a delay, and I initially wasn't patient enough so I had to disassemble and assemble an extra time because of this.

Simply put: If your solenoid value is rusted and the value won't operate smoothly, order the part and install it. This is as easy as any repair could be.
