You have to take the whole outside shell off. Sometimes this is a pain because they use special screws on the covers. If you dont have the bit to do it you can get them with a plier most of the time. Once you have the cover off you will be able to see where the bulb is. Hope this helps

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)

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
