I own a Dovre DB450 propane, which was taken over by Quadrafire a few years back. I bought the stove brand new and have owned for 10 years. My problem as of late is the thermocouple appears to burn out about every 30 days or so. The pilot light is also getting a clump of soot on it about every two weeks, and I need to clean continously in order to make sure the flame is making contact. I am wondering if the pilot assembly is going and why the thermocouple keeps burning out. It does not appear to be burnt on the tip, but once I replace with a new one the unit appears to work fine for a short period. Finding parts for this unit now has become very hard and costly to say the least. I need this unit to get me through the winter and will be in the market for a more reputable stove in the spring...Any suggestions regarding issues I am having and where to obtain replacement parts. I think Robert Shaw makes replacement parts, but no sure about the pilot assembly. Thanks.
