Dacor microwave - LSI or power suppy

my power went out while i was away. when i came home, the LCD display was lit up but blank. it has a line through it sometimes. i think i need to replace either the LSI or the power supply or both. how can i figure out which? i need instructions on how to replace the part (whichever we decide it is) and also how to replace the handle. it broke. thanks!

Most likely the problem is a bad LSI unit. You can find the complete instructions in the Service manual.

  • The part number for the LSI unit is AP3394381

  • The part number for the door handle (white) is AP3391770

  • The part number for the door handle (black) is AP3393660
