Obviously, depends on the skill of the homeowner DUH. I save thousands every year by DIY and almost never have to call in a repairman for anything -- certainly, I have never had to call a repair person in to fix my own mistakes.
I think the problem is you can't read straight... I pretty clearly stated that after cycling the power, it burns for a few minutes the first time. Then after the flame extinguishes, it enters a cycle where the flame only burns for 1-2 seconds (or less) before sputtering out.
Please let me know what your business name is so I can be sure NOT to use you on account of: 1. Your screw-the-consumer attitude ` 2. Your inability to read a clear diagnosis of the problem
Actually, even as a "non-pro" ho (as you say), I think it could make sense. Keeping the blower running probably helps disperse and dilute small concentrations of dangerous gasses that could accumulate in a fault condition...
