The unit was working well for ten years. Without warning, as we pulled the tray out yesterday for use there was no power to the light and blower. What part(s) need replacement? Thanks for the help
There are 2 switches on the left side of the unit where the tray pulls out. You will want to check the switches W10240604 to make sure that they are good. If not then they would need to be replaced. If they check ok then the most likely cause for failure would be the control board W10349739.
