Question about Danby DMW105 Microwave Oven
Hi, The display is OK The keyboard is working, the time rolls down when I press start, it stop when I press stop or when I open the door. I heard a little click when i press start or stop. Nothing else is working, no heating, no light or turning or fan noise. The fuse seems ok, there is no display when I take out the fuse. thanks
Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems. You can find the file via a Google search. In some cases, the problem is a bad connection or a bad relay on the control board. That's something we see from time to time, but it's usually a door switch.

Tips for a great answer:
The microwave oven may be provided with a self diagnostic routine that can be operated
through the touch pad keyboard. To enter the self-diagnostic routine:
1.While pressing the CANCEL keypad:
a) Open the oven door.
b) Unplug the microwave oven for 2-seconds and plug it back in.
c) Release the CANCEL keypad and close the oven door. You will see the following display.
NOTE: The humidity sensor test results will appear on the display after 8-seconds.If the tests are successful, "OK " will be displayed. If one or more of the tests fail, "ERR " will be displayed.. 2.When a keypad is pressed, a number according to the test chart will be displayed. When no keypad is pressed, a blank "—" is displayed...
