Are you saying the gas valve will not turn off? If that is the case shut off the main manual gas valve servicing the unit and then take the necessary steps to repair the defective gas valve or defective power wiring.

It will not shut down unless I do it manually

I have merged your questions. Please only ask once, if you need to add more info, "answer" your own question.

Also our experts are not on here 24 hours a day, some come and help daily, others may come here once or twice a week. So it can take sometimes several days, even a week or two to get a lot of various people helping.

But agree, if this is a serious problem, cut the gas off to the home or building and get professional help if needed
