the problem is the high voltage transformer and its shorted out and it will keep blowing the fuses unless you replace it ,, the part number is XXXXX and it cost about $150 and you can get it at a local appliance parts dealer near you but you need a tech to install it because of the high voltage ,, the unit will hold up to 4000 volts even when its not being used ,, Glad i could help you with your problem today so please hit the accept button for me before you leave so i may be paid ,, Thanks
