Maybe, but how does your procedure for clearing the fault affect this component?
And if the parts guy says he hardly ever sells one of these, it may be a less likely candidate.
It may also be a coincidence that your procedure works, unless you can consistently clear the problem by doing it. The problem may be time-dependent instead of being affected by control settings.
There are several test points in the oven that you should monitor to try to isolate the problem. Connections can also fail.
Since the problem is not intermittent and the oven is not tripping its breaker, etc., you have a good chance of solving this one.
Do not cause a gas explosion.
It was not that long ago that a HO and his wife landed on the lawn at 3 AM because of his faulty dryer install. Since their house was demolished they are now "judgement proof", all in a flash. And nearby houses took some shrapnel, also.
