Reove the unit from the cabinet just far enough to get to the screws and remove the safety shields. hint the last screw is low in the rear of the unit so you will need to get the unit almost all the way out of the cabinet. VERY simple to locate!! remove and replace. all total and not knowing how to do any of it removal was 75% of the 1.5 hours and 25% of the time to replace and re install the unit. now that i know i could likely do it in 30 minutes complete. saved over $500 compared to the appliance repair estimate
