Proctor-Silex. The timer and oven works heats up according to the set temperature
Therefore,the top two knobs work but the bottom one doesn't. I've check the function of the knob. It works fine. I think it's an internal problem - as though something is not connected or connecting properly. I received it second hand from a charity so I don't have a warranty.

Likely the upper element has failed or the contact for it has failed. Either way, likely not worth repairing.
Same promem here. I now I have the solution. Open the Oven and clean the contacts behind the beakering selection switch. It's a little hard to unplug the contacts... Sanded with a screwdriver or something like that and reconnect and you will be able to do delicious Pizza again.
