I have a Sharp Carousel microwave, model R-305EW and
the timer/display has developed a problem: part of one of
the LCD-style numbers no longer lights up.

Is it costly to replace the display on this unit? Is it a
relatively easy job for a handyguy with average skills?



The display is probably fine, likely just needs the connections cleaned
if it uses one of the rubber contact strips, or the solder touched up.
Read the FAQ on microwave safety, then once you've done that this is
most likely something you can fix yourself.
