Question about Sharp R-1481B Microwave Oven
We have had the same problem with this microwave and have changed the bulb but that did not work. Did you ever find out what it was and if so how it was fixed?

The problem is a bad light socket or the door switch. If you know how to do a continuity check with the power cable unplugged then thats what needs to be checked. Unplug microwave.. Take a meter lead insert it into the socket to the light bulb Follow that wire to where it goes as it should go to one of the switches on the door assy. Now these switchs can be tricky so be carefull when you check them as whith the door open theres a terminal that says N.O. that means normally open as when the doors open. The other lead should say on the door switch N.C., that means normally closed so you now that if the wire coming from the light bulb goes to a switch point on the door says N.C. the it shoud read a short from the light bulb socket to both the common and the N.O. side of the switch. If it dosent then the switch is bad. Now on a rare accation the socket itself is bad but thats easy to look at and see if its all corroded and stuff. If this dosent help lets us know and we can assit ya more and by all means if you dont know what im talking about PLEASE dont attempt to trouble shoot this as it could cause bodily harm!! Good Luck
