....when it is off. It's a Tappan approximately 10 years old. Model TGF336BHWE. I have replaced the safety valve and soaped all joints to no avail. The smell seems to be coming from the regulator. But no bubbles in the soap and water solution. My oven guy came out and cannot smell it. He brought his electronic gas sniffer and it didn't pick up much. The smell seems to be confined to the stove area and is very faint, but I have a strong sniffer and pick it up whenever I am near the stove. I have been battling this for two years and think it's getting stronger. I am paranoid about gas smells as I should be IMHO. Could the regulator be the source? The propane tank is full so it's not that I am low in propane. When I get right down there and smell the regulator that's when I smell it the strongest, the oven guy said it's not the regulator, and laughed. Everything has been checked, safety valve replaced, still faint smell. Please help, I am frustrated and worried. Thank You.
