Basically the stove fire up, runs for about 20 minutes and then trips the reset. I feel a very small amount of hot air coming out of the convection tubes, but not "blowing out"! Stove is due to be cleaned so I will make sure nothing is blocked. I hve had the stove only 4+ months and have burned 2 1/2 tons until now. I have not checked the fuse Where is it???? Thanks, Bill (Thinking of copying & pasting into the M55 blower defect thread.....?)
