We see (and repair) this a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid.
This light failure often occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.
Details of our service and critical safety information and disassembly information is at our site, and our link is at
our listing here on FixYa.

You can solder a wire on here to bridge the broken trace. 1 min fix!
Did not read directions on replacing light bulb under micro. Must have blown something. Micro timers, display, etc work...micro does not! Top over display was hot so we removed the display part and found that we burned up some electrical board with black boxes and little pin things and mumbo jumbo back there. How or can we repair this and is it worth it or should we just buy a new micro? We have the Whirlpool MH1150XMS0. It is discontinued. If we need a new one, what is a comparable model that we (lay folks) can just stick in the place of the old one?
