I fix roll laminators in pittsburgh for a living. Check the fuse holder if often melts down, make certain the outlet your machine is plugged into has power. thats a common cause of no power.there are the interlock switches one on the clear plastic cover, you should hear a click when the cover is put in the down position. the other interlock switch is a pin tats goes into the side frame and tris a switch. if your anwhere near pittsburgh i give free no cost no obligation estimates. locally GBCs first hour service rate is $317.00 within 25 miles of pittsburgh, thats insane...
if none of these get your machine running theres a thermal fuse that fails in combination with a bad temp sensor but thats not nearly as common as interlock troubles. post back if you need more help bob
