PDCS1NCYCLSS 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.

Replaced main control board, located at the rear of unit.

Using nutdriver removed access panel on back. Unscrewed water supply line. Using nutdriver removed water inlet valve. The feed line to the icemaker is a pushlock connection so removed feed line. Then reverse process.

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.

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

No self defrost. Measured heater coil with ohm meter which was OK (not open). Ordered 2 temp sensors (there are 2 in freezer, 2 in fresh food sections). The original and the new all meaured ~150 ohms. Replaced one by one. This did not fix problem. Ordered defrost thermostat. Original measured ~150 ohms - new one was ~100 ohms. Unpluged refridgerator. Removed coil panel (4 nut screws) in freezer and light cover (1 small phillips screw). Locate defrost thermostat clipped to top of coils (orange / pink wires). Cut wires and unclipped thermostat. Stripped insulation off of wires and reconnect using wire nuts. Clipped thermostat back to coils. Ran refridgerator without panel on coils to see if coils frosted up again and listend for fans/compressor to stop ( took hours). Opened freezer and viewed glow of defrost heater. Problem resolved.

Poped out with screwdriver the old swithch and unplugged the two wires. Plugged in the wires to the new swithch and pushed it back in the hole where the old switch was before.

Looked up possible causes on the internet, did the trouble shooting: off wait 15 seconds, then on, hit the ice level switch 3 times. No cycling - order a new ice maker. Had already checked water supply line and water filter. Screws in difficult positions to use standard screwdrivers or if you have medium size hands to remove plastic guards. After that was easy to replace whole unit. Cut plastic guards to be able to get at mounting screws for next time. Designers definitely need to think about consumer repairing of items rather than disposable major items not built to last 10+ years.

-Unplugged the refrigerator
-Removed panel on the back of the refrigerator, bottom right.
-Took pictures of existing main board so I would know where everything plugs in.
-Unplugged and removed main control board
-Installed new main control board
-Plugged everything in.

First, I removed all the shelves and the light guard. Second, I removed the nuts that held the fan guard and the freezer back in place (2 just under the fan guard and removed the freezer back. Third, lifted fan guard out of way (being very careful not to crack it..... cold plastic). Fourth, unpugged fan from pug then removed nuts that held fan bracket in place...removed fan. fifth, then removed fan blade and remove fan motor from bracket, removed two wires that went to freezer light (pay attention to where they go) and installed them into the new wireing harness. Sixth, installed fan blade on new motor, bolted new assembly in fan bracket, plugged in and reistalled fan into the freezer, replaced fan guard and freezer back (reverse order of above) and then replaced freezer racks. works beautiful.

I had taken the noise long enough and wanted to get this repaired. I didn't want to pay a repair man hundreds of dollars to do it so i decided to do it myself. I went on to YouTube and found a few videos that showed me how easy it was to do (very helpful).

I wasn't so sure all that noise would come from the Evaporator Fan motor so i ordered it and took the chance. For the small cost, it was worth the try.

All went well accessing the unit and removing the old part. Very fast indeed. However, the snag came when i went to plug in the new part electrical to the existing electrical adapters. The old part had 4 lead connections. The new part had 6. and the wires on the new part were different colors than the existing. I had to use some logic and courage to cut the wires on the new part and rewire the old adapter to this piece. Luckily, i wired everything correctly.

Calling Part Select got me a phone number for the parts manufacturer to help with the splicing but i opted to do it on my own.

The result is i have a noiseless refrigerator again. What should have taken 10 to 15 minutes took half an hour because of the wiring but overall, very easy.

Take the cardboard grill off the bottom of the back it is held on with 5-6 hex head screws. Located the voltage inverter on the tank. It's on the bottom left of the refrigerator. Removed the screw that holds it in place.Remove the jumper wires at the quick connect. Rotate the voltage inverter and removed it. Check the voltage at the plug in going to the voltage Inverter. It should be 115-125 volts. Plug in the voltage inverter to the Quick connect away from the tank check the voltage on the side that would be connected to the tank. If both sides don't read at least 115 volts the inverter is bad. Order a new on and reinstall in the reverse order.

While the switch did last for 9 years, the design is poor due to the failure mode. The failure should be to fail off or not able to turn on the lights which would be inconvenient but would not warm the refrigerator contents. Arcing at the contacts eventually caused the switch to "weld" closed. It is not obvious that this is occurring so it took some time to recognize why the temp inside the ref was high while the freezer was OK. Replacing the switch was easy once it was recognized as the problem. All that was required to replace the switch was to remove the screws holding a fiber cover and then pulling off the aluminum cap which covered the switches. Unplug the switch an squeeze the keeper on the switch to release it and pull down. Pop the replacement switch in place and plug the wires harness back in. All in all it took much less time to replace than it has to write this up. T Pope

Unplugged the appliance for safety. Removed two 1/4" screws that held the assembly in place. Carefully removed the wire guard that retains the glass shield. Unscrewed old light bulb and replaced with new part. Reversed the steps after cleaning glass cover.

The existing light switch was very hard to remove. I ended up having to grab it with a pair of pliers and pull it out. Once it was out, it was very easy to put in the replacement and it seems to be working fine.
