We had the same problem. I took off the bottom plate, cleaned the toaster, reseated all of the connectors on the heating plates, timer, and switch, and the toaster started working again. Only one connector was slightly loose (but it was still connected with decent contact). I am not sure what fixed it. If that did not work, my next step was to purchase replacement parts online and swap out the switch, timer, and heating plates (in that order). We have an older model than yours, but I suspect that the parts are similar. The parts all look very easy to replace. These units are intended to be repaired and not replaced.
