Now that you scared the guy to death .....


its probably a door switch that jammed when someone slammed it . look in
where those plastic spades on the door poke into the front there are
some squarish black switches that get pushed when the spades go through
the holes .
Each switch has a little ( probably ) red nub that clicks when you push
it in . You can reach in and push those with something to see if they
mechanically click .
If you do find the bad one you can unplug the wire from the back of it
and note where they went and take the switch to some repair senter for a
new one . Put it back the same way it came out . You dont need to do any
of those silly tests .... those are for ovens that ha door damage .
Just dont touch the wires coming out of a big capacitor ( silver oval
like can mounted to the bottom or rear of the case )
