ZSG27NGSASS General Electric Refrigerator - Instructions

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.

Dis-assembly only consisted of three screws, but for the not-so mechanically inclined, I would suggest taking a picture of the ice crusher blades before removing them from the auger shaft.

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.

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.

unscrewed old filter by hand, installed new filter.

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.

After having replaced the main control board and three thermistors, the fridge was still having difficulting getting cold enough - it wouldn't get colder than 15F / 42 F. Uniform frost on the evaporator coil ruled out a sealed system leak, so the remaining culprits were the either the evaporator fan motor or the compressor.

I read that a failed control board is almost always the fault of a bad evaporator fan motor, so this item was the most likely suspect.

To get to the evaporator fan motor, I had to remove, in this order:

1) Icemaker
2) Auger motor and brackets
3) Icemaker bracket
4) Freezer lights and bulb sockets
5) Evaporator panel
6) Evaporator plenum cover
7) Evaporator fan motor bracket

The greatest difficulty lay in swapping the new fan motor harness. Two pins in the harness connector were used for the evaporator thermistor.

I had to carefully cut through the old connector (using a Dremel) to extract the crimped-on pins for the thermistor, then reuse them on the new connector.

The fridge is now maintaining -5 F / 35 F in the freezer / fresh food sections.

This was so easy even a caveman could have done it. (sorry to all you cavemen out there.) Order the parts and they arrived promptly a couple days later. Even with limited mechanical abilities this was an easy project. Only a few screws to remove and a lock nut to take off. Just to be sure your on the right track there is an excellent video to follow on this exact repair on this site.

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.

The repair is easy, just pop the grill off around the ice and water door, then there are 4 screwws to take out so the touch pad can be moved out of the way to unsnap the old door assm. and snap in the new one and wait about a year and a hald to order another one!!!!!

Removed old bracket (2 screws), ordered new bracket and installed. Discovered that the bracket had been redesigned due to numerous failures as described above.

Of course, the first thing I did was remove the ice cube container from the freezer, and dump the ice cubes. (Conservation note: If you're in a place with water conservation rules, dump the cubes in a big pot and save them. If they melt, use the water for your house plants.) Following the advice from another DIYer, I let the container warm up before doing anything further.
Turned the container (I'll call it the "tray" from now on) over, removed the two screws holding the front cover with the Phillips screwdriver, gently pulled the cover out to disengage it from the rest of the machine.
Getting the next part out was tricky because it didn't want to release just by pushing in on the tabs on either side of the front assembly. That's where the two table knives came in, courtesy another reviewer. Be careful here not to jam or twist too energetically because the plastic housing is still quite breakable.
Just to be safe, I unscrewed one more screw that held the little bracket holding the rod with the spring on it and disengaged it. Then I discovered that I had to unclip the part that holds the auger in the front part of the assembly and slide the auger out of the way so I could pull the broken part out.
Having done all that, putting the new part in and reassembling the whole thing was pretty easy.
Slide the new part in, carefully rotate the auger back into its place, slide that assembly back into place, replace the clip holding the end of the auger, be sure the long rod engages the ice crusher gizmo, replace the screw that holds the rod in place, hook the front of the drawer back into the proper slots, rotate the cover back into position and replace and tighten the two screws.
You're done! The ice cubes you took out will probably still be frozen, so you can dump them back into the tray and slide the tray back into the freezer.
If you're cleverer than I am, maybe you won't need to do all the little things I did, but even so the whole exercise took less than 15 minutes--the ice cubes didn't even melt!

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

I lifted the old switch with a flat screwdriver, attached wires, and popped into place. Saved 80 bucks for a repair call.

I simply did a google search search for my model number, found the part, thanks to the schematic that is on the site and ordered it. It fit perfectly where the old glass shelf was and now I have restored my shelf space. Thanks PartSelect
