    Last time i saw those fuses blow the electrician zip tied the N wire to the heater.
    Is is common for the fan wires to rub out on the fan mounting brackets.
    I checked out all the fan wires. Replaced fan delay. Everything checked out. Reversed the legs and it’s been going since the day after my original post

    OK

    All im saying is the control circuit is Single Phase. Doesn't mater L1, 2 or 3

    Compressor rotation yes especially with scrolls.

    Youll be back

    Only time I've seen a resolve like that was with a delta corner grounded b phase service.
    I replaced a single phase blower motor and it kept pulling high amps.
    I moved the one lead off that b phase and the amps fell in line.

    I agree and think by chance with all the moving of wires around to find a cause might have temporarily fixed the issue.
    That circuit only has a crank case heater ( via a aux ) and a low / high pressure switch in play. Unless it's got the oil options.
