In attempting to change the lightbulb underneath, I did not unplug the unit and the wires crossed and shorted the unit. The unit will not turn back on now. Is there a fuse that I can change, or did I permanently damage the unit?
See this causes and fix it. God bless you
First check is the main
fuse of the unit. On countertop units, you will need to take the shell
off. The fuse will be close to where the cord comes through into the
unit. OTR units, this main fuse is usually behind the control panel or
possibly behind the vent. Usually the fuse is obvious if blown,
otherwise test with an OHM meter, if open, replace fuse.
Some
brands will also have a thermal cut-off fuse in the incoming voltage
line to the control board. Older Maytags and Samsungs have this fuse in
it. This thermostat looking fuse is usually above the oven cavity
somewhere under the outside shell. Sometimes you can get to it through
the vent of OTR models. Test with an OHM meter, replace if open.

If it went dead almost
immediately after pressing the Start pad, that's usually a shorted
high-voltage capacitor.
If it went dead
several seconds after pressing the Start pad, that's usually a
failing
high-voltage transformer.

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 in about a
week or so.
At
our Web site, you can get details of our
service, plus we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
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.
The lights can can be
inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly
affect the fan operation or inside light, too.
We're
happy to help you with free advice and we'd appreciate your
thoughtful rating of our answer.

We replaced the board behind the control panel. $130.00. If you do this make sure you can put the wires back the right way. My husband finally got it and our micro is working like brand newThanks to all who tried to help.
