    breakdown ,air con stopped - then fan locked .auto electrician replaced solenoid but hooked it up backwards so overide switch was on when it was off . I fixed solenoid and overide switch , replaced high pressure switch as that was the original fault but now fan won,t engage automatically

    Check your fan hub to see if it is leaking air, or if there is a problem with air supply or wiring connections. My experience has been that when the h7b goes bad it will lock solid, but that isn't always the case.
