I had the same problem with Whirlpool that you did. I bought a used model WED5500XWO, year old.
The control board burned and melted and damaged the Assembly Interface. I called Whirlpool and they connected me with the safety dept. They sent a tech.out,he sent pictures and called Whirilplool and reported the incident said they would call me back. The next day safety dept.
called back and because l bought it used they would not be responsibale. The concern l had was to report the incident. The person l talked to had a attitude of non concern and did not address the problem and said it was the plug. The plug had nothing to do with the problem.
It was the relay on the control board that has a spade connector on it. Whirlpool doesn't want
to hear about dangerous problems.
