I have a 1 month old Harman p61a and 3 times this week i have come down to find it off with the status light blinking 5 times "unable to ignite in 36 minute ignition window" i turn it off, turn it back on and it begins to feed pellets into the burn pot and then lights right up. The burn pot isn't full maybe 2 clumps of ash but was puzzles me is that if it failed to ignite I would expect to find a handful of unlit pellets in the burn pot but there isn't a single fresh pellet in there. It's as if it burned out gracefully but then tried to light without feeding pellets. i am going to open a case with my dealer but wanted to see what the forum said. I have plenty of pellets in the hopper when this happens and i clean my burn pot daily.
