ZISS480NMA General Electric Refrigerator - Instructions

Unscrewed the light cover beneath the microwave with a phillips head screwdriver. The bulb is very tiny and has 2 straight parallel prongs that slide into 2 small holes. Grab bulb from both sides with each hand firmly and slide STRAIGHT out (no twisting or pushing). Don't worry about breaking even though it may take a fair amount of pressure to pull out. New bulb arrived within a couple of days. Due to high shipping cost, suggest buying 2 or more bulbs at once. Bulb is often used as a kitchen night light so that is probably why I only got 9 months out of it.

Used by pass filter and problem disappeared. Of course wayer is now unfiltered. This is a GE design flaw. Also replacement filters are outrageously expensive and do not last long. We have good water here and I'll stick with the bypass.

There were not two screws as the instructions said. There was only one screw and I had to firmly pull it out after taking out the one screw. Then, to put the new one in, I had to line up two slots on two knob-like things and push it in firmly. Then screw the one screw in.

Other than the two-screw problem, it was easy.

The replacement ice maker that GE supplies for my old refrigerator is a little different than the original. The electrical plug changed from a round plug to a square one. They include an adapter for it, but DON'T USE IT. There's not enough room for the bulky cord and connector. I got a much cleaner installation by taking apart the old and the new ice maker, and then splicing in the old connector into the new ice maker. You need to carefully unscrew a circuit board inside to wire it in, and it'll be more secure if you solider 3 wires instead of using crimp connectors. The instructions also tell you to use your old 'ice breaker', but it won't fit on the new ice maker. I just left the new ice maker's ice breaker on, and it seems to work perfect.

when the ice maker runs through its cycle, you should be able to hear the solinoid valve open, letting water into the ice maker. this was not happening for me. you can dissconnect the plug on the valve and put the two probes from a multimeter in the plug and set for AC volts. when the ice maker runs its cycle, at the end you should see the meter jump as power is applied to the valve then turns off. this means you do have power to the valve so the valve is defective. turn off water supply to the valve, disconnect the water supply tube to the valve, remove the screw holding the valve, disconnect supply tube to icemaker then hook up supply tube to bottom of valve, screw braket back to refrig, install suppy back to valve, turn water back on and check for leaks and your ice maker should be working properly again.
these guys were really fast on delivery too!

Took panel off back of inside of freezer section, took off old sensor from the evaporator, spliced new sensor into the existing wires, waterproofed spliced connections, snapped sensor back onto evaporator, then put panel back on the inside of the freezer. Really, it took only 10 minutes to fix. Now refrigerator defrosts like it used to, and temps have settled in at specified temps.

Unplugged the refrigerator and turned off the water to the ice maker valve. Removed the water line at both ends (small crescent wrench). Removed the cover from the water valve area (two Phillips head screws). Removed the valve (two screws - small nut driver) and pulled off the two electrical connections.

Installed the new valve with the reverse procedure though the holding screws didn't line up with the existing holes in the refrigerator metal frame. I let it go with one screw holding ... didn't have a drill with me to make a second screw hole.

Replaced the old water line (from the wall to the valve) with a steel-reinforced hose.

Cut the female metal connector from the old water line up to the freezer and it fit nicely into the push-in outlet from the new valve. Turned everything back on and waited for the ice maker to cycle.
To my dismay, the leak had been coming from the plastic line that goes from the valve up to the ice maker. It had split, spraying water. Replaced that and everything works fine.

Lesson learned: Don't assume water near the icemaker valve actually is from the valve or its water connections. Watch the whole system cycle a couple of times to see what's really happening. Glad to have a new valve but the basic problem was the icemaker tubing.

Frig and freezer were defrosting and refreezing other than normal. Home warranty contractor told me ice maker was faulty. Purchased new ice maker. Unplugged frig, loosened 2 screws with nut driver. unplugged old ice maker, lifted old ice maker out. Took old fill cup off old unit and put on new unit since new fill cup was a different size. Swapped ice maker insert from old to new unit. Plugged in new ice maker, slid over the 2 screws, tightened, and plugged in frig power. New ice maker works fine but still have defrosting and refreezing problem. Figure old ice maker probably works just fine. New contractor still trying to solve problem. Have had problems with this GE Monagram keeping proper temps since it was new in 2005, don't recommend it.

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.

First I removed the ice maker. Second I removed the back panel and overhead panel above ice maker. Third I pulled down the drip trough it had a styrofoam base under it. The trough heater had to be unplugged to remove the trough as well as the drain hose. Forth I seperated the styrofoam from the trough and peeled off the old heater which had burn marks on the foil. Fifth I applied the new heater plugged it in and attached the drain hose to the trough. Last I reassembled the unit. Refridgerator works great now and it only cost $45.00 for the heater. The GE repair service quoted over $950.00 and did not list the trough heater as the problem so I would be spending more and would have required several repair visits.

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.

Shut off power to the refrige. Removed old icemaker, using large hammer. Installed new unit.

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

New ice maker only used 2 screws and the old one had 3. This was no problem. The old ice maker had already been removed. Just loosen the 3 screws and unplug the cord to ice maker. Only problem with ice maker was with the cord, which I had to use the supplied adapter. It was too long and in the way when reinstalling the ice bin. The ice bin had a small notch area on the bottom left. I used a plastic tie to bundle the cord into the notch. Carefully placed ice bin and no problem. The first part I received was damaged and was replaced 2 days later by a brand new part. Customer service charged for the replacement part but said they would credit my charge card within 2 to 3 weeks for the damaged part. Its been a week and if they follow thru like the said I woild give Part Select 5 Stars for service and Parts.
