The lights illuminated so I new there was power. The door switch and thermal fuse tested as good. The lights on the front panel worked so I believed the control board was bad. Ordered one but it did not help.So I ordered the control panel and it fixed the issue . Good news is I can return the control board for a full refund (Great Policy). Much easier to trouble shoot problems without the fear of spending money without a positive result. The how to videos are a great help even for a guy like me who has repaired production machines for 30 years.
