Question about Sharp R-1610 Microwave Oven

The inernal fuse doesn´t hold

Hi,
My Sharp is R-9H 10. The internal fuse is gone. I tried to change it but when I turn it on its Ok but when trying to use any program the internal fuse will explode. A 10-hamp fuse is not holding, it is necessary to use a 15hamp fuse?
Can someone tell me what is happening or how to get technical support in order to me to this problem fixed please?

Apparently you're in the UK where 220V is used, so a 10A fuse would be correct.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Sharp microwave oven r-9h20 display flash(00:00)) and no keypress action


On Sharp R-9H-series ovens, when the membrane keypad fails, as in your case, since these parts are no longer available, the oven would have to be retired.

Sorry to bring you bad news. These were great old workhorses.

Only had the machine a couple of weeks and now it won't switch on. I had left it plugged in and switched on over night (I have tried changing the fuse and that didn't fix it)?


Possibly internal fuse or thermal cut out gone. perhaps best to have checked by Technician.....Check your power source is okay first...

you need to remove the outer cover,then carefully discharge the high voltage capacitor with 2 insulated screwdrivers or an insulated jumper wire,then test this and the high voltage diode and the internal ceramic fuse for continuity

The microwave is absolutely dead as if getting no power - circuit breaker is OK. Died suddenly...just nothing there when tried to use.


Possibly the internal fuse. Unplug unit, remove all case screws on the back of the micro. Slide the case toward the back and remove. Look for a glass tube type fuse, simular to automotive fuses of the past. It should be located near the controls. If bad, I have been able to find replacements at Radio Shack. If the fuse is good, I'm sorry, it's beyond my microwave knowledge level.

Microwave blew up after cooking an egg


Yes the internal fuse will have blown. I would also think the door latch switches and monitor switch will also need re adjustment
