Whirlpool JT358/ALU Service Manual needed

[1Pawell]

Could you please kindly help me to find a Service Manual with circuit diagrams for Whirlpool microweave oven Model JT-358/ALU (858735828641)?
There was an accidentaly high voltage from the socket and now the owen looks dead. Possibly power 24V supply burnt as no signs of life on the display and the only (glass) fuse visible is ok. Thanks in advance!

Measure the resistance of the PRIMARY of the power transformer on the control board. Since you will probably have to dismount the board to do so, also check for burnt printed circuit foils. If there is a ceramic fuse, make sure its OK.
