I had to replaced the plastic cradle (holder locker) that holds the three door switches. Also, the interlock switch did not ever close. I Ohmed it out and it was always open. Lastly, there was a grease or some kind of junk in one of the quick connectors for a switch that would not make a good contact. I replaced the quick connector with one I had on hand. The machine is now good as new. Thank you for having drawings and parts and quick shipping. I will call upon you again as I have for many other repairs here at home. You folks are providing a good service.
