Diagnostics on the oven all show ok, but the oven never gets out of pre-heat and gets extremely hot. I replaced the thermostat, but still have the same issue. Is replacing the relay board the next step?

Hi Ken, thank you for the question. As you have already replaced the thermostat, it seems that there is an issue with the relay board, part number PS12722623. It sends power to various microwave parts to operate the microwave. You may need to replace it to fix the issue. We hope this will resolve your problem!
