Very simple repair. Watched the video. Part pops off from bottom and has 3 plugs on back to plug back in to new one and pop back into place. Very simple. Literally took less than one minute. Only tool used was tiny flathead screwdriver to push the tabs underneath in to pop the old unit out. Part was delivered very quickly. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
