I am not at home right now, but I am on the phone with my wife. Top freezer is indeed very quiet and we cannot feel much (if any) air coming out of the small holes at the back. As for the bottom freezer, we can hear something, but are not sure - the hole at the back is difficult to get to right now.
Also, the fridge part is also quiet with little air flow, but it seems to be able to keep its temperature relatively okay... but is seems a little hotter than normal. I will try to get more precise temperature measurements when I come back home tonight. Hope this helps out.
According to the manufacturer, this fridge has the TDM System (Time-Divided-Multi-Evaporator system): Each compartment has an evaporator, microprocessors and a refrigerant-control-valve to control the refrigeration cycle. The 4 evaporators enable improved efficiency and humidity in the fridge. Food odor from the refrigerator does not affect food in other compartments because the cooler and air flow systems are separate.
Does this mean I have 4 fans in there? If so, then the top freezer one could be the culprit, right?
OK, let me see if I got this straight:
Fans are 11-6 and 11-3 in the 11 sub section of the drawing. 11-6 looks like it is the top one, whilst 11-3 looks like it goes in the square hole in the bottom section.
OK, new info. Bottom fan runs OK, Top fan is not running: I removed the back to expose the coils w/o unplugging the fan power wires and just placed it so I could the fan; I then replugged the fridge and I cannot see the fan turn, even in power freeze mode, whilst the bottom one is OK. It seems you were correct!
Exactly, it is the white one "water wheel" type.

Just to let you know: I managed to dis-assemble the motor without too much trouble.
I restarted the fridge by by-passing the error codes and everyting is running OK (on the fridge side, that is...)
Got the part today, installed it and... not sure. The fan still doesn't seem to run (everyting its plugged, no error code when the fridge is plugged in. The bottom fan is still OK. It would think that the top fan would work all the time; from my understaing it pumps air from the compartment and shoots it thru the top, though the ice maker at the ice maker.
One thing however, the temperature that is indicated seems the right one.
I'll let it run overnight to see. If not, I'll bring the bad motor to my workplace and put 12 volts on it to see if it turns or not. If it does, then the problem will be somewhere else. Any thoughts?
OK... I feel a litlle stupid - I just check while I held the door switch and I confirm that the new motor is indeed working (D'Oh!). For some reason, I don't need to do this with the bottom drawer for the bottom fan to work. Anyways, temperature started at +5°C at 8:00 PM and is now at +1°C. We'll see how low it will go tonight.
Unfortunately, I don't remember if I actually held the door switch when checked the original motor last Friday.
Should've read +15°C and now at +1°C (even better). I'll let you know.
1) The old motor is in fact dead: 12 Volts on it = nada. Resistance between pins is in the kOhm range. I plugged the + an - on the 2 pins that showed the less resistance value.
2) Temperature was -21°C on the display this morning, but in fact -6°C as read by a thermometer inside: however, the freezer is completely empty. With stuff in it, it did not go under -2°C with the old fan. I guess this is OK. I'll check with frozen stuff in it tonite,
Well... not a success: Even loaded since this morning, the top freezer stays at about +8°C with a -17°C set-point and bottom one at around 0°C. I know the fan works now.
Just put "power freeze" option for both compartments - they are getting lower (bottom now at -8°C at air exhaust) Top at +5°C at exhaust that goes to the ice maker.
Getting frustrating here... any thoughts?
When I came back tonight, it didn't seem to be constantly running.
Here's the situation now: Display still at -17°C. Top is stable at +6°C, bottom, after going down to -8°C, got back to 0°C, even in power freeze mode and is starting to go back down (oscillation) The fridge compressor is running and generates heat at the back of the fridge side. Freezer compressor is running, but no heat seems to be coming out of it...
Yes it is. Also, bottom freeze oscillates between -8°C and 0°C, so there is cooling going on, only seems to be not strong enough.
Doesn't seem to be, no. If I compare fridge side to freezer side, fridge side is exhausting warm air from the back of the appliance, whislt the freezer side is not.
Bottom oscillating between 0 and -10°C now. Top is now getting under +5°C. (I have thermcouples installed inside tonight- geeky but useful)
My thoughts exactly. Oscillation is taking about 30 minutes between low point and high point - bottom is empty, whilst top has stuff in it.
I just got a theory: bottom is swinging because it is empty. But it is getting slowly but surely to lower than -15°C. Top is also oscillating, but at much less an amplitude, because it has stuff in it. It is also getting lower but at a much slower rate. Could it be that the temperature sensor is off? It is reading -17°C, but the real temperature is 15°C higher whilst the bottom sensor is OK???
Display temp is at -19°C. Power freeze automatically turned off last night and normal freeze is currently selected
Bottom section is between -15°C and -21°C - oscillation still present.
Top section is between -4°C and -6°C -not enough... but it is consistently (and s-l-o-w-l-y) going down. I have a graph showing the temperatures over time, but I cannot attach it here.
At 07:00 PM:
What diagnostic tools are left that we can use?
I'll get a local guy to check that then..<
