Big thanks to everyone who posted here. I have a TOA-60 that had the function selector switch fail just after 3 years and outside the warranty period. Google directed me to Ebay and a replacement switch for $10 & change. This was the only website that had any useful information on the details of disassembly and reassembly. I especially appreciated the explanation on how to remove the knob. It only took me a little over an hour to do the job. Cuisinart continues to sell this oven and this switch is frequently the thing that fails from what I have read on multiple sites online. Planned obsolescence at its finest.
