I have a sharp 1900 w/r 24 at microwave, display shows a single green dot, when switched on at the wall I just hear a normal sound as if the unit is operating but nothing works


In this case as the display does not show a clock then it seems the program controller is not working correctly. So check power - step down supply, if the pads are responding- if not faulty pads. Also the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean,solder and reset the board.

Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

Now unless the display works and the processor starts to switch on the MAGNETRON , the table and light will also switch on as it must heat.

So it is necessary to check the main controller unit as it seems to be the suspect..

The display works (clock, mode, etc) I can push


We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week or so.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.
