CDA CD907SS oven. To confirm, its the case cooling fan, not the circulation fan. Otherwise, the oven heats fine. I'm confident in extracting the oven and locating the fan. I have a multimeter and a reasonable set of tools. If it is the fan I am happy to replace it. Before I do so, I wonder whether some kind soul could tell me how to prove that it is the fan that has failed, and what else it might be. Many thanks - Regards - Doug
