Have older Tappan built in self cleaning oven -- temperature control knob stuck and won't turn except to clean with other knob on clean -- have cycled thru a cleaning ok but still stuck after
Hello, and thank you for using this service. I'll be helping you with your problem today.

Do you have a model number so that I can better assist you? And are you saying that the temperature knob is physically stuck and won't allow you to turn it?

No model # XXXXX knob will not physically turn except to clean
OK so unfortunately that means that your thermostat behind the knob (the part that the knobs attaches too) has just failed. There really isn't much you can do but to replace the thermostat itself to fix the issue most of the time, but you'll definitely need the model number in order to order the correct part for your model number. If it's older, the part may not even be available anymore, so you may just need to remove the thermostat and take the thermostat apart from the shaft down to the base of the thermostat and see if you can find one of the washers or gears jamming and see if there is anything you can do to get it working again. On these older units, it might be a good idea to have a technician look at the thermostat because depending on how handy you are, you will likely need to take the thermostat apart and put it back together to see what might be jamming inside the unit.
