I have a Sharp microwave (Model R1480) over-the-range model. Has the smooth touchpad style membrane buttons on the control panel. Anyway, the button that controls the Work Light (over the range top--it's mounted in the bottom of the microwave) no longer works. At first I thought the light bulbs (two of them) burnt out, but after replacing them, they still don't turn on. All the wiring between the bulbs and the control panel appear intact. I guess the button/switch in the control pad doesn't work. The strange thing is the button for the exhaust fan, which is right next to the light buttons, does still turn the fan on/off. Can a single control button go bad on these?
Anyone know if I can repair just this worklight switch/circuit (replace the wires?), or will I probably have to replace the whole control panel (I've seen it for ~$50 online--ouch)? At least if I do have to replace it, it looks like it just pops in and out, and the connectors do the same. Any advice on this is appreciated; thanks.
