I checked for voltages on CN75 (9 pin connector). From pin 1 to pins 2,3,4, I get 8 or 9 volts. From pin 1 to pins 6,7,8 I get about 1 or 2 volts. These are read on a 300V scale. When I open the door and measure on the fan connector (red, white, and black), I get no readings. Does the fan even run with the door open? There's no visible door switch (I think there's a magnet near the hinge).
