I started to notice oven was intermittently heating up. Some days it reach desired temperature and sometimes would not heat up at all. After reading similar stories I decided the problem could be one of two part failures. The igniter assembly or the heat sensor arm. I ordered both. The ordering process was painless and the parts showed up the next day. After watching video on how to replace and a few turns of the nut driver the oven was up and running perfectly thirty minutes later! My wife hates this site because she wants new Appliances but appliance pros make it too easy to fix them yourself!
