              Diode               

• Remove the 2 Phillips screws, then pull off the white rubber feet and open the triangular screws underneath. Special tool.
• The bottom can be pulled off. Remove the cable holder to be able to work better
• Unscrew the two circuit boards and disconnect the motor and the sensor cable. The sensor cable with 2 wires remains on the small circuit board.

Step 2

• Unsolder SR3100 diode and solder in new diode. 3 A 100 V. The diode had continuity and at the small control board was only 2.5 V at the red and black cable.
• The temperature sensor resistor is marked green. This has about 95k ohm at room temperature.
• I also checked the blue marked temperature fuse for continuity and the purple marked contact switch.
