I have a Harman Advance ignition problem apparently. I cleaned my stove this past weekend and lit it off automatically with no problem. Yesterday the unit ran out of fuel and when it was reloaded started back up as usual but this time the pellets did not ignite. I cleaned the pellets out the burn pot and ran it through the ignition cycle again. It never ignited. I understand after 4 cycles the unit is supposed to give a blink code on the control panel. I couldn't wait that long. The igniter LED on the control panel lit up each time I tried it. I am suspecting the ignititor assemble is bad? As I mentioned previously, it worked just a few days ago and I didn't do anything to cause it to fail. I am wondering if the ignitor light on the control panel is supposed to go out on a failing ignitor? Is there a way to test the ignitor? Anyway, I ended up manually lighting the stove. I appreciate any info about the ignitor on this unit. Also, I have seen older posts about replacing it. I would take any info on where to get one and how to replace it. I have seen different part numbers around the web.
