Dacor CPS230 dual oven. I just cleared a recurring F1 fault/beeping by cleaning the latch assemblies and the oven temp thermostats mounted behind them. I first cleaned those for the top oven, and did not fix. Then I cleaned those for the lower oven, and F1 fault went away. Lots of dust buildup on the lower oven temp thermostat was likely the problem, maybe causing a slight continuity between one of those leads to the metal case below it. I appreciate the earlier posts and registered here so I could contribute.
