    Hi TELL here,
    can anyboby assist me in the reason why the 250ma fuse is blown on the PCB for this m/c. have tested components etc, nowt down to earth. had tried it with a 160ma fuse it worked for awhile TEMP REPAIR. but obviously underated.all speeds on motor acheived ,lights on,etc.
    the part no for the board is 77×9211 on the connect-dist site, if you enlarge the picture you will see 2 together. anybody got a wiring diag,to show what these are inline with, and protecting.
    sorry lads bit long winded, but would like to know why!.

    Presumably it could happen if air flow was restricted by a clogged filter?
