Question about Kenmore 62622 Microwave Oven
I changed the light bulb under the hood, without thinking to unplug unit first. Big mistake, it must have shorted the fuse because there was a pop and then micro went dead. Any help is much appreciated.
Unfortunately, there is a good chance that when the bulb shorted out, it damaged the control board. The only way to know for sure is to do some electrical testing with a volt/ohm meter and the wiring diagram located within the appliance. The relays for the fan and the lights are part of the board. The power should always be disconnected when these bulbs are replaced or the board will be damaged. We would have an appliance repair person take a look to see what the deal is with the microwave.

The problem is likely on the control panel, which we repair nationwide 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 often can affect the exhaust fan operation, too. The lights and fan can be inopoerable or stuck on.
