ZISS480DMD General Electric Refrigerator - Instructions

The very first symptom here is important! The door water dispenser is not working but the ice macine is working. You may only have a frozen water tube in the door so do the following before diagnosing that your solenoid valve is bad: 1) the tube usually runs under the front of the refrigerator and usually has a quick disconnect. Undo the connection and press the dispenser. If water comes out of the tube you have a frozen or blocked tube in the door. 2) Immediately adjust the temperature in the freezer and warm the freezer compartment as much as you can without destroying the freezer contents. Wait 24 hours. This will usually unfreeze the line. Do not waste your time with a hair dryer. NOW, if this doesn't work and you are convinced you need to order and replace the solenoid, follow these steps. Assemble your tools first. I needed a good ratchet set and a screwdriver. A shop towel is helpful for spilled water. A light is handy. Pull out the refreigerator to gain access to the rear of the unit. Unplug the power and close the water valve (older homes, you may need to actually shut the house water supply). Remove the screws which hold the cover over the lower half of the refrigerator. On the left you will see the solenoid. It's always good to see that your new part matches the one you feel needs replaced. They may not match perfectly due to changing design but they should be very similar. One screw holds this part in place and access is very simple. Now simply unplug the electrical connections. In my case, one blue "blade" type connection (powering the water) and one red "blade" type connection powering the ice maker. They are not the same size and this coupled with the coloring means you will not accidently switch them. pull the tubes clear of the solenoid. This is simple and needs no explantion. Grab your new solenoid and reattach both the electrical and water lines (two, remember, ice maker and drink dispencer). Replace the single screw. Re-attach the rear, lower refrigerator cover and go to the front of the unit to check the water. You can listen carefully and hear the power engage from the new part bringing you water. Clean up, replace the refrigerator back to its place and look really tired when your wife sees that you worked "so hard"! You probably saved at least $50-$80 from a service call which can now be used to take the family to dinner after your "exhausting" 15 minute workout of removing about 10 screws and wheeling the unit in and out of place. Writing this article took longer! My 4 year old worked harder holding the flash light!

I went to a GE repair center to explain my problem, the service center reccomended that I have a techinician come out o look at it. $75.00 for the visit and what ever labor and materials wuld cost.

I went on line to see if there were others having this same problem and found that there were many with the same problem.

After reading some of the ways that people found out what was wrong ...it became a matter of three components, the timer, heater or thermostat.

I tried the most common component and the less expensive one first , the thermostat switch I installed it very easily snipping two wires and attaching the news using wire nuts I used the diagram on this website to pinpoint the component and there has not been a problem since.

Model includes filtered ice maker and water dispenser from front of unit. Water maker just suddenly stopped working but ice maker continued to work fine. After some phone calls to trouble shoot at a high level, I figured it was worth a try to buy the replacement part of the most likely culprit and see if it did the trick. Would have cost maybe $150 or more for service tech to make house call, provide the part and do the switch. Buying the part was only $40 and replacement was easy. Remove access panel from behind fridge and identify valve. It has intake water from the filter then has two outbound lines. One to ice maker, one to water dispenser. All function is in one part, but each outbound line has its own functioning valve. Unplug fridge, turn off water supply, disconnect all connections from old valve and reattach to new valve. When re-hooked, be patient in allowing water to re-fill line before coming out of dispenser in front. Likely to doubt it works, but surprised how long it took for water to fill line resevoir.

Unscrew old filter and remove(counterclockwise). Line up arrow on new filter with arrow on connection housing. Turn clockwise till resistance met. Do not overtighten. Follow directions. Simple.

Unplugged the refrigerator, turned off the water supply, and then removed the back cover/access plate. Observed and made wiring notes to ensure I install the part correctly. Unscrewed the bracket holding the water valve assembly, and lifted it up to see and remove the three water lines (one input, two output). The input or supply line is a compression fitting...just use an adjustable wrench to loosen the nut and lift off the line. Then remove the two output lines by depressing or pushing in on the white plastic rings that surround those two holes ...the lines just slide out, but you have to push in on those rings. Remove the two electrical connectors...just wiggle them off One connector was very stubborn but it eventually came off. Try to be gentle, and pull on the connector heads...not on the electrical wires.
Assemble the lines and electrical connectors on to the new part. The two output water lines just slide in...you dont need to push in on the rings. You'l feel them seat into the valve. Don't worry.
Put it all back the way you found it, turn on the water supply, and plug in the power cord. Check for leaks. I had no leaks and was very pleased. This is so easy a chimp can do it, but let everyone think otherwise! No biggie.

Since it was making ice I new there was water getting to the water valve on the fridge. I found the water valve on the back of the fridge, put a voltage tester on the water dispenser side of the valve, had someone push in the dispenser flap on the front of the fiidge and found there was 120v. That told me that the switch was good and pretty confident that the valve was bad.
Upon reeceiving the replacement valve I removed both electrical leads on the valve remembering witch side goes to which, turned the water line off, removed the water lines, matched them up to the new one, plugged the leads back in on the valve, turned water back on and tested. There will be a little air in the lines, but once that is out the water will flow at a steady stream.

I removed the old temperature sensor by cutting the wires. I attached the wires of the new sensor with wire nuts and mounted it in the same bracket.

First of all, the larger white plastic tubes in this thing are 5/16" OD, which no plumbing store seems to stock. At the lower left rear end there are 2 tubes, one for water and one for ice, that are doomed to fail being in proximity of a heat source - they essentially get cooked to the point of becoming brittle and cracking. The smaller tube and union can be easily found, but do yourself a favor if the larger one cracks and order the plastic tube and water tube union here, and just cut off the brittle part and amend the old tube using the union.

I applied some tips learned by reading other reviews. So before I started I grabbed my trusty vise grip pliers and a small screw driver. I locked onto the switch actuator, the part that the refrigerator door pushes in, with the vise grips and pulled on it just hard enough to get the screw driver inserted in the right side to push in the catch clip so the switch could be pulled out further each time the catch clip was depressed to the next detent. Then I used the screw driver on the left site to encourage the switch past the detents on the left and very quickly the switch was out of the mount. The wires from the refrigerator pulled out with the old switch. I unplugged the old switch from the wires and plugged in the new switch and shoved the new switch back into the mount, wiggled it a couple of times to make sure it was secure and the job was done. Once I applied the vise gripes at first, the whole job took less than a minute.

I had to remove all of the shelves.....part of the ice maker.....the rear cover over the freezer coils.....There were two wires that came from the back of the freezer that were also incorporated with the fan motor plug from the factory....This caused me to cut all of the wires from the new motor and soider them to the existing plug and shrink wrap the connections. If GE would have supplied two new ends I could have cut only those wires added the ends and inserted them into the new motor plug thus eliminating an extra hour and a soildering iron,,,,In my case not a big deal however not a project for those who have trouble with repairs using these type of tools.

This story starts with a GE side-by-side refrigerator that has always had wide temperature swings and a temperamental water dispenser. The ice maker was not making ice, and the built in digital thermometer showed it was running warm. I suspected that the heat exchanger was full of dust and so looked there. What I found was that the condenser tank was hot to the touch and the fan wasn’t running. As an experiment, I aimed a fan at the it for a while I saw that the freezer temperature dropped back to normal.
.The fan is marked as 11.2 DC so I checked for voltage at the fan and found some. With three wires and no wiring diagram I wasn’t sure this answered all the questions, but hooking the fan to a 12 volt power supply didn’t get it to spin.
I priced parts at a couple websites before using partselect.com . They also have a good diagram to look at (Sears diagrams are really poor). I ordered the part with 2-day shipping; it arrived on time, was correct and fixed the problem.

I first shut off water flow to the fridge. Examination of the package (which was not exact in appearance to the original) demonstrated that the electrical connectors were well-insulated so I arrogantly and successfully proceded without disconnecting the power. My fridge is old enough that the model doesn't appear exactly on anyone's list so I wasn't alarmed that it took an extra 10 minutes or so to noodle out how to adapt the slightly different inlet cowling and electrical cord with extension, but the device is pretty simple.
Soon I loosened the two mounting screws with a nut driver, used a screwdriver to pry away the plastic snap-in housing over the electrical socket on the fridge inner wall and pulled away the electrical plug. The original water fill tube remained in its cavity, ready for re-use.
The new unit's mounting points matched the original screw locations perfectly, as did the fill cowling - which on the replacement icemaker has two possible attachment points. The new unit's electrical connector required an extension pigtail to adapt to my socket, but it was included in the package. The extra cable posed a minor cosmetic issue because it hangs in the collection basket a bit, but that will soon be remedied with a tie wrap.
After the water was restored and an anxious wait of a few hours, we had well-formed ice cubes that weren't all stuck together and the stalactites haven't reappeared.

A week earlier, we had frozen water all over the freezer section which obviously dripped from the icemaker. We turn off the icemaker and cleaned the freezer. Upon turning the icemaker back on, water continuously pours out of the ice tray. This time, even turning off the icemaker does not stop the water from flowing through. I checked and cleaned the water valve, reinstalled it and it still does not work. I had to crimp the water line and even remove the water filter to make sure there will be no water leaks.

When I got the new water valve, installation was a snap as I have already removed the old one. After installing the new valve and putting back the filter, everything is back to normal.

Procedure for removing/replacing the water valve:
(1) Unplug the refrigerator and move it so that you have some working space in the back. If there is a mechanical valve in the water line, close it so that when the hoses are unplugged, there will be no spills. If there is no mechanical water valve, you can simply crimp the hose with a rubber band or a cable tie.
(2) Use an adjustable wrench or a screw driver to remove the screws on the bottom panel. My refrigerator has 4 big screws and 1 small one that is used to anchor the water hose.
(3) Pull the panel up slightly to remove it. The water valve is mounted with one screw at the bottom-left corner.
(4) Use a screwdriver to dismount the water valve.
(5) Unplug the electrical connections to the water valve. My refrigerator has one Brown and one Blue connector. Remember which plug goes to which connector.
(6) Place a towel under the water valve and use the adjustable wrench to remove the main hose connection.
(7) Next, remove the hoses that to into the water valve outlets. On my refrigerator, these hoses are of different sizes and have quick-disconnects. I simply have to press on the collar at end of the hose, pushing it towards the valve to release the hose, then pull on the hose.
(8) Prepare the new water valve by removing the plastic cover that protects the connector for the main water line.
(9) Connect the main water line to the new valve using the adjustable wrench.
(10) Connect the two hoses of different sizes to the valve. You only have to push them all the way into each valve and slightly tug on them to make sure they are locked in place.
(11) Re-connect the Brown and Blue electrical connectors to their original location.
(12) Mount the new water valve into the back of the refrigerator (one screw).
(13) If possible, quickly check that the new valve is working properly: If you have a mechanical valve in the water line, open it and make sure there are no leaks near the valve or inside in the icemaker. You may have to plug in the refrigerator power to complete the initial test.
(14) Replace the back panel with the 4 screws and anchor the hose to the back with 1 screw.
(15) Once everything is back in its place and the refrigerator is on, cycle the water dispenser several times to run fresh water into the hoses and the new valve.

I unplugged the electrical connection. Then I removed the 2 screws holding the icemaker in place. I lifted out the old icemaker unit and put the new one in place. Then put the 2 screws back in and plugged in the new unit.

The icemaker started making ice very soon after turning the unit on.

used a screwdriver to remove screw and unplugged part. Plugged in new one and secured with a screw.
