ZISP420DXBSS General Electric Refrigerator - Instructions

the first thing i did was replace the water valve at the bottom of the refrigerator but that didn't work so then i spent more time researching the problem on your site and your diagnostic said to replace the ice maker so i ordered it, took the old one out, plugged the new one in and we had ice the next day.

Removed outer trim by pulling it carefully out of its clips. Then disengaged the electronic display card by grabing the bottom of the card to disengage the card from the upper clips. I leaned the card forward and disconnected the wire connectors. Removed the 4 screws to take off the frame that contains the funnel. Remove the broken funnel from clips. Note study how the spring is engaged. Note position of the rubber funnel how there is a gap for the water tube. Removed the rubber funnel and attached to new funnel dispenser. Start at one end of the rubber flap and work around engaging the rubber into tabs. Replace the Funnel dispenser back into frame. Make sure the longer wire of the spring sits flat on the plastic frame and that the right elbow of the spring raps around the edge of the funnel. Secured the frame assembly back into the Refig using 4 screws and attached out trim starting withe bottom tabs engaged first.

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.

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.

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.

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.

Actually this was a two part repair of which I purchased both parts. The micro switch Pt # PS296176 and also a double outlet water valve Pt # PS304374 from Parts Select as well.

The difficult part was accessing the area to get to the micro switch.

The trim had to be removed, then the cover.

Then one unplugs the board and removed the face plate which also contains the micro switch.

Once removed the two electrical terminals had to be disconnected, the micro switch installed and terminal reconnected.

Then reverse the removal procedure.

Then on to the double outlet replacement.

Suggest watching the installation video for the replacement although it was really a straight forward repair.

Two things to remember.

1. Unplug the fridge

2. Shut off the water to the dispenser

Overall it was not bad at all.

This was my first attempt at refrigerator repair and it went well.

Good luck on yours.

unscrewed old filter by hand, installed new filter.

Replacing servo was not hard, but did not solve problem. Searched some more and the cure is to remove the light bulb from the dispenser. Seems that old bulbs draw too much current and cause the control panel to fail in sending signal to icemaker motor. Removing the bulb cured this fault and the control panel worked fine.

First, had to use punch tool to pop out electronic face panel. Face unit still connnect via wires. Use painters tape to hold against refrig. Next, Remove ice/water dispenser and also tape to door. This will give you access to solenoid. Remove the 3 screws holding it in place and unplug fsolenoid from Face Panel. Screw new solenoid and place and connnect to Panel. Goood idea is to unplug regrig. while doing this and put a little WD-30 on shaft of solenoid. May want to order new screws, could be rusty, that hold solenoid in place. Sounds a bit complicated but not that bad a job. You'll save over$100 over GE's service.

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
