I checked the line voltage on the outlet and found it right at 250-253vac without a load. This circuit is rated at 30AMP, the machine's breaker is rated at 20AMP, and the machine is supposed to pull a max 8amp on the line making all things reasonable. So why no power-on? Nothing spins, no lights on the front-panel, nothing but the first-stage of the power supply humming slightly. I checked all internal fuses and all are good. Questions: Is 250vac too high? Someone mentioned 208 which is a large enough spread to make a difference in a smart power supply. If so, how do I modify the 36 for 250vac? Is there something I am just missing? Like a (very) concealed switch, safety interlocks, hard disk locks, wheel locks, leveling? Room-temp is a comfy 68degrees F give or take. All the high-voltage wireing is relatively new and looks good. It goes to a breaker in a modern breaker box. How would I check for a ground-fault on this line. Why would my dryer run and not the computer if there is something wrong with that line? I'm sure you can appreciate moving a several-hundred pound computer in. I'd love to see it work.
