It sounds like the thermocouple is bad. If a replacement doesn't fix it, there are some adjustment screws for the gas valve, but they need to set with a pressure guage, so that might require servicing. Desa filed bankruptcy in 2008, but the following website provides parts: http://www.desatech.com/ Good luck, and hope this helps.
