Upon arrival i found the unit not sending power to the board. I verified 125v going to the board. I then proceeded to check the fuse and found it blown which told me there was short.i found the short to be on the red wire, it was rubbing against the door of the unit. I presented the findings to the home owner, he elected to have wire repairs and fused replaced. Unit was back up and running after repairs. Supply temp was 121 degrees.
