It should default to the highest power setting.

If not, you can reset it by unplugging the power for a minute or two, plugging it back in, and setting the clock.

Otherwise, refer to your owner's manual.

SOURCE: Door Latches Broken on Sharp R-3E68 Microwave oven

I think it's a Hong Kong model.

Normally you can find Sharp's specific country page by entering one of two URL formulas, but replacing the xx with the two-letter country code of that nation:

http://www.sharo.co.xx
http://www.sharp.com/xx

Sharp Hong Kong is at http://www.sharp.com/uk

Look for a customer service or contact link, then see if they have a parts link. If not, you'll have to call or e-mail.

If that fails, you can take a few high-quality photos of the part you need and I may be able to cross it.

If you or a friend decide to look into it, we have critical safety and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

On most Sharp models, you press Clock, then the digits for the time, then either Clock or Start.

You may have to open & close the door, then try it.

SOURCE: everything seems to be working but it doesn't heat anything

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

Sharp Convection Microwave won't heat and turntable won't turn.

I typically find it is not door hinge issues but door switch issues, especially with sharp. You may heve a little movenent in the door hinge and that is allowing the door hook to move up and down on the plunger for a door switch that is probably a bit melted due to bad connections. If you check the door switches and look for any browning around the terminals where the wires push onto the switch you will probably find an overheated connectoion. Replace the bad switch and run better wires and better termninals to the new switch and it will probably be fine.

When plugging in a Sharp R-33st microwave, nothing happens except a flashing time, no buttons seem to work, any ideas?

it sounds like this is not a new microwave,, is it getting on in years?
if the microwave was discounted from the mains when it was pluged back in the power surge could have blown the circuit bord inside it,, this is quite common, it may be cheaper just to buy a new microwave than spend good money on an old week unit
