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but the quality dropped and kept dropping until very little Sharp gear is sold here, in fact I heard they have almost withdrawn from the European market.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.

if you`ve "just plugged it in", press clear / cancel on the panel, clears the dispaly

You can try and unplug it for 5 minutes, push the on button to make sure it's completely discharged. Then plug it in. If it does the same thing, it's toast. Getting it repaired will cost about the same as a new one on sale.

if the display does light up but it wont turn on, Broken door switch, broken in the Open position. But if there is no display at all (no clock, for example) then look at the power supply chain (including the fuse)

Level it and it might fix this t

Something must have spilled into the mechanism and dried there. You'll need to access and clean it out.

Hi Timothy, your Microwave Sharp Half Pint, does not have any receptacle for batteries, therefore, if unplugged, it cannot generate any sound As Robert Oliver suggests, notice that another device nearby, that if it has batteries, may be making that sound I hope you find the origin of the beeper Greetings Franco Dosil Hola Timothy, tu Microondas Sharp Half Pint, no posee ning?n recept?culo para bater?as, por lo tanto, si esta desenchufado, no puede generar ning?n sonido Como te sugiere Robert Oliver, f?jate que otro aparato pr?ximo, que si tenga bater?as, pueda estar haciendo ese sonido Espero que encuentres el origen del emisor de pitidos Saludos Franco Dosil

You should check for 3 volts on sec coil supply for magnetron but do this check with the hv capacitor and hvr disconnected if 3volts is present , most probably your magnetron is deffective, replace it with the same type

Sounds like a door latch needs an adjustment that only a qualified technician can perform for safety reasons.

Try unplugging uni t for 10 seconds,then plug back in. If that doesn't work, contact a technician. For service.

Check your users manual for installation instructions. then reverse engineer them.
