I have a Panasonic over
This not a good sign, from your description it indicates the high voltage transformer is shorted possibily caused by the magnetron becoming defective. The money would be better spent replacing the microwave oven, the repairs to the present unit will be close or exceed the cost of a new one.

The top right corner of
If the door is warped cheaper to replace the whole oven, the 3cm gap is a hazard because you have dangerous radiation leakage, the levels are exceeding safety standards and should be removed from service immediately.

Had power surge at home. Exhaust fan runs all the
The fan speed is (or better said it should be) regulated by the digital control board. In your case this board has been fried by the power surge.
The oven is probably fixable, just that it's not worth the effort: a new power source and a new board (which are surely fried) cost about $350. To that you must add the very possible failure of the magnetron - which would cost you another $200 to replace. Add to that the costs for the shipping of the parts and the wasted time with finding (i couldn't find them online) and installing them and you end up way more than it's worth.
Better just cut the losses and buy a new one.

Turns on and runs for 2 seconds before turning off
See if this describes
what's happening:
- Put
in time, push start and unit runs
for 2 seconds, relay clicks, unit goes off. Cook time on display goes
off and clock time comes back. Bad upper interlock switch and charred
connector
If so, see http://207.234.249.73/mwd/safety.txt , http://207.234.249.73/mwd/disassembly.txt and http://207.234.249.73/mwd/doorsw.txt
Otherwise, if
the digital programmer circuit / controller does not get a feedback
signal from the inverter for a period of 3 seconds, the controller will
stop the cook cycle.
That may be a loose connection in the wiring between the
inverter, magnetron, and/or control board, or maybe one of
those
components has failed.
Due to the lethal
voltages used and produced in inverters, I do not recommend that an
inexperienced person work on these.

Can not open the door
Hello :
That could happen because of bad door switches . I don't think that there's anything you can do by yourself unless you are a handy . Calling for repair is better suggestion . A microwave is capable of giving you a serious electric shock even when it's unplugged from the outlet .
good luck .
please rate !

Fuse blows on microwave switch on
one of three things shorted could cause this: H.V. diode,capacitor,or the magnetron tube, take screw driver and short terminals on capacitor before touching anything inside the case, then chk resistance on capacitor should show infinite after needle settles, diode should show hi resistance one way and a lower resistance in the other direction(use the RX100 scale not the RX1) on both parts diode should not show very low resistance or it could be leaking,mag is a different story,it can be chk'd but in a different way
