Only the keyboard is working

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.

Sharp R-9H84B-display black, cleared display shows "Conv Mix, 88:88 Auto". Short time all dark again. Hit clear happen 2 times then, all dark, no power, can't clear won't start, nothing works.
R-9H84B - May 29, 2017

I would suggest pulling the control board out and looking on the foil side (opposite the component side) for "ring cracks," most likely on the low voltage transformer's connections.

The board may have the screen-printed reference designator "T1" near the low voltage transformer.

Also be sure the fuse is not easy to turn with your fingertips when it is in the holder. If it is, the fuse holder is too loose and must be replaced (not just squeezed with pliers).

You can order a fuse holder, part number WB06X10034 for $6.49 (subject to change) from the Pros here.

If you have any keypad issues, please note that the membrane keypads for this model have long been discontinued.

FixYa does not directly notify us experts of responses, so if you have other questions, please contact me directly.

The colon between the numbers on the clock, example 8:00 won't stop blinking even after I set the clock and hit the clock button again.
Sometimes the correct procedure for setting the clock is to press the CLOCK or TIME OF DAY button, then enter the time on the keyboard, then press the START button instead.

Otherwise, as long as you can enter a cooking time and your oven operates normally, then don't worry about it. On some models it is normal for the colon on the clock display to blink all the time.

Good luck.

Microwave doesn't work
Sounds like you have a faulty control panel. I would use a meter and test the power from the control board to the magnetron and circuit board. Chances are the control panel is faulty

I have a turbo chef NGO. Today during warm up it blew both 12 amp fuse on the F1 and F2 circuit. Is this a typical issue? I replaced the F1 fuse, plugged the oven back in and it did not restore power but it didn't blow the fuse again. I replaced the F2 fuse and it blew both fuses immediately upon plugging the oven back in. The oven was working properly until this happened.

NEFF C57M70N3GB Microwave combination oven Keeps turning off after 23 seconds The microwave was part of a second hand kitchen which we've had for 6 months and all was working until yesterday. Whichever mode or time setting you put it into, the microwave turns itself off after 23 seconds. Resetting temperature, time, mode etc; and press start, it turns off after 23seconds each time. If anyone can throw any light onto the reason it does this i would be very grateful. It matches the lower oven and i cannot get a matching replacement. Many thanks Jeff
