Query: another oven timer issue

I have used my toaster oven for maybe 3 years, usually about once weekly. Definitely not getting heavy usage. But last week I noticed that the toast was badly burned, and when looking closer, the knob was turned to the left for the clicking timer for toast, but when the timer dinged, it usually turned off. This time the timer kept going and turned the knob to the right, which is the continuous cook option. It will burn everything if you don't stay right there with it. I am throwing mine away- it is too dangerous with this fire hazard.It's a shame there are no repair options, but this is the last time I will buy this brand.
