Hi Steve it’s unusual for no one to jump in, when you undo the four screws the face plate should come loose, it will hang on the control wires that are attatched to controls, the control knobs should pull away to allow you to release controls from panel, I say should, as mine were tight enough to make me think they would break. After looking at the price of the panel and the fact it is a very common issue I made the decision to repair not replace, photo pretty self explaining, used carpet moulding with silicon to bond and strengthen cost all up around $10 , it’s now stronger than original
