I guess we have had similar problems. I have only had mine running for maybe 4 weeks total since I got it 5 months ago. I worked great for the first 30 days, but then wouldnt light. I sent it back to them for repair, and their customer service was great. They told me a piece of teflon tape was cloged in the gas line and fixed it. It worked great after I got it back for another 3 weeks, but then had the same issue. I decided I was going to take it apart, and did. I manage to get it working for about 3 days, but then it did the same thing again. I am planning on taking it apart again, but havent found the time. Its such a stupid problem, but it wont work in its current condiition. I thing in a few months, I may just upgrade to the hydrogen pro and try to fix and keep the mini as a backup, because when it worked, it worked very well. Just in case you didnt know, fuzzy logic controllers are ment to be used on bottled gas, and standard controllers are for generators. Im not sure exactly why, but it stated several time in my Setinel manual to turn fuzzy logic off if using a generator.
