I had 2 tasks. One was to replace a burned-out bake unit in a wall oven. The repairman, Mark, had the part in his truck and was able to replace it immediately. Second task was to diagnose problems with the freezer unit of a side-by-side refrigerator-freezer, where frost was building up inside, and the freezer has occasionally leaked. He diagnosed it as a clogged drain in the freezer, which he unclogged. He explained everything completely as he worked and said that if problems with the freezer persist or return, I should call him back. The whole job was done quickly and cleanly.
