Maybe your house is haunted.

I apologize on this forum's behalf for Jannie's answer. While I myself do not know the answer to your question, I googled "gas oven turning on by itself", and got a lot to read. I am linking one response below.

I recommend calling Capital rather than going through e-mail. You need to speak with a live person.

I second BFF's recommendation. Call them directly on Monday morning at 8:00 Pacific. Ask for Bob, the head of service. I know sometimes another person or two has done some service call intake, but insist on Bob if possible. Then follow-up with him every day or two if he hasn't been back in touch with you.

Independent service companies doing work for Capital (and every other appliance manufacturer out there) are hit and miss. If you're not happy or haven't gotten resolution with whomever they've sent, call Bob immediately afterwards and tell him what you've experienced.

Thanks very much, everyone. I spoke with Bob today and he will send someone from a different firm out--hopefully soon. In the meantime, I've unplugged the range.

My capital which i purchaed in 2014 is now doing the same. Did Calital help?
