Hello
We do not have any videos on the GE combo model. We did complete the LG combo, it may be similar and help you on the teardown. model. See the link below. We did have the service manual with the diagnostics, error codes and wiring diagram. See the link below for the service manual.

Hello
You are correct. You only have one evaporator fan motor. Check the evaporator to make sure there is not a heavy frost build up. If there is a heavy frost build up. You may have a part of your defrost system not functioning. See manual links below.

Hello
Go to the link below (Pooling Water under Tray Service bulletin). This sounds like it is your issue.

Hello
See the service manual link. I would start with the Service test mode on page #53 in the service manual link provided below. This will give you the stored fault codes to find your issue.

Hello
See the service manual link below. Start by running the unit through diagnostics. This will show stored error codes. The ice maker test is Service Test #25 in the manual.

Hi, I have attached the tech sheet and ice maker tech sheet for the unit. Sounds like you have replaced everything related to the icemaker. Could be a door switch issue or wiring. Does this unit have the wiring at the bottom of the door? These wires are common to break. Definitely check the wiring where it comes into the door weather it’s at the top or bottom.

Hello
See complete manual link below. The water filter housing is on page #53.

Hello
Go to page #91 in the service manual link attached below for detailed instructions.
1) Remove the RFID filter.
2. Remove the 1/4″ screw on the left of the board
cover.
3. Disconnect the wiring harness.
4. Unsnap the four retainers to remove the board.

Hello
Unplug the harness to the water valve and take off the secondary line from the main water into the icemaker. Does water, come through it? If so, you have a defective diaphragm in the valve that is not seating properly and letting water come through it . The inlet valve diagnostics are on page #57 in the Service manual link below. The Ice maker diagnostics are on page #44 . All other diagnostics are in the manual. Normally it’s the valve or ice maker. Very seldom the main board.

Hello
The UR code meaning below. On page #20 in service manual link below.
Display for additional rinsing.
• Show additional rinsing in sensing unbalance.
• Method of releasing the display.

Hi. I have attached a service manual for a similar model.

Hello
See the wiring diagram on page #35 in the link below and and the parts breakdown.

Hi,
Yes, the defrost timer would stop the compressor and evap fan motor from running. The cold control/ thermostat would stop both from running as well if faulty.
The defrost termination would not stop the compressor or fan from running. I would first test your thermostat.

Hi,
It’s not a common thing to keep taking out the capacitor on these. I have seen faulty motors take them out. Possibly a bad timer could take it out as well or a short to ground, or improper voltage. The part number for the capacitor is WP8572717. Most meters should hand a microfarad setting to test capacitors. uf stands for microfarad and the capacitors will have the microfarad rating stamped on them. For example 50uf. So you would test to see if the capacitor is reading out at the proper microfarad rating.

Hello
The main control board handles the defrost system. See manuals below.

Hi. Sounds like a possible control issue. Hard to diagnose this though. Would have to catch it in a failed state, when it’s not cooling to see whats not running properly. Power in and power out is the best way to diagnose a control. If you have proper power going in and not the proper voltage coming out then bad control . The power surges that happened very likely damaged the control. I have attached the service manual for you. You might be able to run through the diagnostics to get a better idea of whats going on.

Hello
See the link below on the Thermador T30IF900SP Refrigerator-Freezer Opening Door Assistant diagnostic flow chart.

Hello, it may be possible through the test mode. Before entering the test mode all water must be removed manually first. We have attached the service manual for you and the test mode instructions are on page 26.

Hello
E91 is a UI- Main board error. Did you replace them both at the same time? We have found by replacing one at a time does not work. By replacing them both at the same time they sink with each other. I have provided the diagnostic and service manuals. I would run it through a field service mode in the mini manual link below. This will tell you if there are any other stored error codes.
