Fixing the start button
Pressing the start button on my Breville BOV800XL toaster oven also triggers the convection button, and sometimes the Fahrenheit/Centigrade button, instead of turning on. I have to press the button many times, carefully, before the cycle actually begins.
I suspect the button is flexing the PCB behind the control panel and display.
How do I get the cover off, and how could I fix this?
