Sharp Microwave Ovens - Popular Questions, Answers, Tips & Manuals

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

Line Fuse
If too much current passes through the microwave circuitry, the line fuse will blow. If the line fuse blows, the microwave won't start. To determine if the line fuse is at fault, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. In addition, you should investigate and resolve the problem that caused the fuse to blow. If you don't resolve the underlying issue, the new fuse will blow too. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the line fuse.)

Either the high voltage capacitor or the high voltage diode has failed. Its possible that the magnetron has open circuited but its unlikely. Get someone who knows microwaves to have a look. Be warned ! These high voltage parts can cause serious injury or kill you if you are not careful.

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