We know that PP lurks here, and now we know that Whirlpool does, as well! We would like to here the straight 411 on any issues with that control box
The second electrician was here today. He diagnosed two primary issues-he found that the plumber had some exposed wire around a cap when he opened the thermostat controls on top of the WH. Second, he replaced the existing 20/20 breaker with a 30/30 breaker. Everything is working perfectly now.
The first professional who was here told me I needed to replace the wire and never tested anything on the WH or the panel. The second looked at the wire and said it was 10/3 and that it was sufficient. I'm glad to have had the feedback from everyone here. It really helped me understand all of the techbical terms to ask the right questions.
Thanks to all who responded. I'm glad I had the second gentleman do the work rather than the first.
Two things would have sped up our diagnosis.
1.Knowing that it was a 20 amp breaker when the heater had 5500 watt elements,and,
2. Verifying that it was 10/2 wire, (10/3 was/is unnecessary),and not 12/2 or 12/3
