Most microwave ovens now use a similar method for setting the time on the front. Many different kitchen counter appliances like microwave ovens are made by the same manufacturers and sold under different brand names or with similar parts and designs. Microwaves, coffee makers, air fryers, convection ovens and even some toaster ovens have clocks on them these days and trying to set all the clocks during Daylight Saving Time can be a hassle. Fortunately, most of these kitchen appliances have adopted a general method for changing and setting the time: The Clock Button! If your device has a Clock button you typically only have to hit it once or hold it in, either type in the new time or advance up or down to the new time on the display, and then press the Clock or Start button to save your changes and get your out of "time changing" mode. Many other small appliances are following this same methodology. It's quick and easy!

A lot of times on the sharp microwave they have a series of plastic levers and linkage that have to push up and down to latch your door and close the switches inside if one of the switches inside does not close properly the machine thinks the door is open so it will not allow it to run or heat when you open the door look at the little hooks that are sticking out of the door and try to push them up and down and make sure that they have a spring action to them if they do not or one is loose then that is where your problem is

It is unlikely you will be able to get a replacement without sending to the manufacturer. This is likely to be expensive unless its in warranty.

I haven't even seen a microwave drawer yet - I don't think many are sold here in the UK. Sharp used to make quality equipment but the quality dropped and kept dropping until very little Sharp gear is sold here, in fact I heard they have almost withdrawn from the European market. The microwave drawer is almost exclusive to Sharp as they were the inventors and own the patent... Although the arrangement is different the working principle must remain the same and there are two distinctly separate parts, namely the timer and switching and the high tension side that generates the dangerously high voltage that drives the magnetron. Testing the high tension side is beyond the scope of the home tester though some basic ohm meter checks can provide a rough idea. An ordinary multimeter will allow the testing of the switching and supply side by checking whether mains power is being supplied to the high voltage transformer, or inverter if it is that type. The difficult part will be dismantling the unit for good access and I suspect the second most painful problem will be obtaining replacement parts. My last experience with Sharp told me their parts are priced not to sell, forcing users to buy a new appliance rather than repair. One small circuit board would have cost me more than double the cost of a replacement appliance.

If it's only 6 days old, I'd return it to where you bought it or I'd call Sharpe for warranty repair. I wouldn't open it up as there are potentially tamper stickers which will void the warranty.

Take the body cover off and locate the regular glass fuse near the control panel wiring and make sure the fuse is good. A blown circuit breaker is the first clue that the fuse could have also blown. I have rescued tons of microwaves for the lack of a 50 cent fuse.

Hi and welcome to FixYa. I am Kelly. High voltage capacitors can and do fail when a microwave is used for long periods of operation, when the unit is operated with no internal load and sometimes for no reason at all other than the capacitor had an internal failure such as corrosion or a break down of the metal strips inside of it where the strips can make contact with the the case. I have been working on microwaves since the 70's and often there is no apparent reason for the failure of the HV cap.. They just sometimes fail.
However...... there is also a power diode in the microwave that is connected directly to one terminal of the HV Cap. If the power diode has failed it can cause subsequent failure of the HV Cap. The Sharp Power diodes can be found here: http://www.repairclinic.com/Sharp-Microwave-Parts?s=t-FH-DZA119WRKZ-%3d%3db113a6c41

You use and ohm meter on resistance to check the diode AFTER removing the terminal of the diode from the capacitor. NOTE: the capacitor must be shorted across the terminals at least 3 times with a screwdriver while holding the handle only to prevent a horrible shock.
Once the diode terminal is disconnected from the HV Cap read resistance in BOTH directions by reversing the test leads on the terminals of the diode. One direction will read resistance and the other direction it will read open / infinity. Any other reading is a failed diode.

You check the capacitor using an analog (scaled vs digital display) ohm meter on R X 1,000 or R X 10,000 and watch for a jump on the meter just as you touch the terminals EACH time you reverse the leads. No jump or... steady resistance = bad Cap.

Sharp Capacitors can be found here:
http://www.repairclinic.com/Sharp-Microwave-Parts?s=t-FH-DZA119WRKZ-%3d%3db113a6c12

Just note that either a CAP or Diode failure can cause the main fuse to blow at the end of the power cord in the fuse holder.

Fuses are normally either 15 or 20 A Slo-Blo fuses and can be found here:
