Sounds like on reassembly you reversed wires to door switch.
switch might have letters C NO NC (common, normally open, normally closed) one wire goes to C common, the other to NC normally closed. Try reversing the wires.
If you use meter measuring continuity meter on C and NO should be high resistance until you press switch.
meter C to NC measures low resistance until you press switch then measures high or infinity (open)

Sounds like the problem is in the high voltage. Most common would be magnatron, capacitor and diode. For safety reasons this should be checked by a professional. Look in your owners manual because some high voltage parts have a longer warranty than 1 yr.

You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

You have a bad secondary interlock (lower door switch) or its mount is damaged or out of alignment.
We have
the service manual for this model and have uploaded it to our
site here to help you.
You will need the free

Even though a door
switch clicks, it may still be bad inside.
Door switch
or mount trouble is usually caused by slamming the door or by opening
the
door while it's cooking without hitting the Stop pad first.
There are
plastic mounts inside the microwave which hold the door switches and
onto which the door latches lock when you close the door.
The screws on these
mounts may be loose. If they get too loose, the switches will not be
activated properly.
Sometimes it's
a broken tab on the switch holder, allowing the switch to rotate just
out of position. This tab
can be hard to see, since it is under the
bottom edge of the switch.
If you only need a
switch, you can order a universal type here for $5 postpaid.

Door switches
If one of the door interlock switches
is not switching properly or there is a condensation problem on the
sensor control panel, either can cause the turntable/light/oven to
come on even though the "Starts" button has not been
depressed due to the wiring of the switches.
Check for faulty door
switches and/or contaminated actuators.
I hope that helps.
