I have a new Electrolux oven which among other things checks for incoming voltage. Specifically, it wants 240VAC and gives an error message if the voltage is outside a 7% +/- window. I had a Tech check ours which was aborting and he found that each leg of the power was measuring 122VAC but when both were tested together in the outlet, the reading was 212VAC which is outside the reuqired range. I don't understand this at all and want to know what, if anything, we can do to increase the voltage to the required amount. Thanks
