There are a number of variants of your microwave, I should also point out the engineer manuals do not go by colour coding but pin location and layout.
To be sure can you send me a picture of the rear spade terminals so I can identify the power regulator fitted and confirm which terminal is which.
Sorry for the delay responding can you take a photo showing the circuit boad (J1 and J2) where the blue and black wires go to.
I would have said the black wire which goes to F1, is live and should go to brown wire of the inlet, however to double check would want to look at the tracking of the back of the PCB to ensure the internal fuse is connected to it, so you may have to remove the board to check the track on the back.
Hi Debra yes this shows the 15amp fuse on the same track as the black wire so the brown live should be attached tot he block wire shown as attached to the fuse.
Just wondered how you got on this evening?
