SQ JTD32 dryer's door open light stay on forever

[super80]

Today, I changed a bad door switch, then test it, dryer working fine, so I push the new switch back to it's position (metal socket), but when I put it back, the connector of the switch accident touch the ground (dryer's housing), short then spark occurred, after that, I found the door open light stay "ON" forever even I close the dryer's door.
I checked the wires that connected to the switch, they seem looking good, but there's no power on those wires!! also check lint drawer switch and belt switch, those switches working fine but also no power found on the wires that connected to them. I also checked there's also no power supply to the limited thermostat!!
Now, I don't have any idea which part I still need to check, any advise??
thanks very much

You blew the computer board. If you are handy you could take it apart and fix the blown trace or solder point, otherwise, send it off to ALJ.

But I have tried switch the computer board, but same problem still persist!! I also tried to use the same computer board on the other dryer it works fine with no problem at all~~?
any comment??
thanks anyway!!

Hmm...In that case I would check all your harness plugs for loose or burned pins. Failing that, I would get out the wiring diagram and start working backwards to find where power goes missing.
