I have a Harman P61, 3 years old. It was running great, then the power went out. I turned the stove off. Partially burned pellets in the burn pot. I cleaned out the burn pot. When the power came back on, I turned the stove on. The pot filled to the edge and did not ignite. All the lights are on. Then the feed motor light went off. I emptied the burn pot and shut down. Then restarted the stove and it did the same thing. Any ideas of what I might try? Any suggestions would be very helpful. Thank you.

Have you tried unplugging it, wait a couple of minutes then plug it back in.

May want to try cleaning out the igniter area under the burn pot. Anytime mine doesn't want to start up, that's usually the case.
 
jenrn, I can't tell in your Avatar picture - is your stove plugged into a UPS or surge protector ? Our local power grid in Central Maine is notorious for power surges and brown outs, which are cumulatively hard on your $$$$ circuit board.

Yes, it is plugged into a surge protector. And my avatar picture is my old stove--vista flame. Guess I need to update with my Harman!!

My Harman XXV does that occasionally and the fix is the same for me. The startup sequence for that stove is about 5 minutes of intermittent auger action, filling the empty burn pot about 1/3 full, followed by a few minutes of no action, waiting for ignition I presume. If it gets to the end of the wait period and hasn't started I scoop out the burn pot and restart. It's always cool to the touch so the ignitor never got power when that happened. I had the ignitor replaced under warranty a few years ago but that didn't fix the problem, and I use the word problem loosely because it only happens once or twice a season and hasn't happened yet this season.

My Carrier heat pump does something similar. There's a 30 second delay from compressor on-off to blower on-off and about 5-10% of the time the blower will start and run for 5 minutes before the compressor starts up. There is a 5 minute timer to keep the compressor from restarting after shutoff and a 5 minute timer to delay restart after sensing low suction pressure so I believe one of those sensors flubs up occasionally. The dealer says that's normal for Carriers and the system is 15 years old and still runs perfectly otherwise.
