Does it work now after resetting the upper limit switch ?
If so, could be a bad upper limit or a problem with blower motor not starting when it should causing it to trip.
Thanks,
Robert

You should have a lower limit switch mounted on back wall beside the control box. Between control box and booster motor/pressure switch.
