How to troubleshoot ASEA DBT12 Transformer when it doesn't power up?
If your ASEA Transformer doesn't power up (the display doesn’t light up and the fan doesn’t spin), first check the pedestal and shore cord circuit breakers to ensure dock power is available. If the problem persists, have a qualified electrician check the input power to the unit.
