I was wondering if there is a way to unstick our oven thermostat
(Tappan gas oven)
The part costs about sixty dollars, not bad , but if we force the knob
with a wrench the oven still works fine. Why did the knob suddenly
become impossible to turn? (this happened overnight- one day it was
fine, the next,stuck.) Even when we took of the knob,not easy, and use
a wrench this thing is really hard to move. we're afraid that well get
it to turn on but not be able to turn it off.
