I have an old gas oven that is having a temperature problem. When it's turned on, the temperature keeps rising and rising, not stopping at the set temperature. It gets up to 500+ degrees.
This trouble started after we moved the oven from one house to another, and didn't use the oven for a year. I'm not sure if either of those facts could have caused the problem.
The oven has had a bad thermocouple before, which we replaced, and it was working well for 5 years before it was moved.
Can a thermocouple die in 5 years and cause this problem? Is there something else that could cause it?
