Our Sharo R-1471 over-the-range microwave (about 10 years old) quit
working. The interior light and fan stay on continuously, and there is no
response to most of the front panel buttons. The Sharp web site had no
indication that parts/manuals were available directly from them. Is it
possible to get a service manual, or at least a schematic for this unit?
How about parts availability? I took the control panel out and found no
obvious damage. Tracing back from the 2 larger relays on the bottom edge
of the board, it seems that Q27 is open. Marking on the part is "A223"
Does that stand for 2SA223, or is it a house number?

Someone slam the door?
