I have a Breckwell P2000I that after a normal cleaning (vacuum out ash and clean glass) will not run. When I turn it on it starts exhaust fan, feeds pellet, starts fire and then it shuts down and turns on room fan. If I hold the on button after that to try and reset, it turns off room fan, keeps exhaust fan going and feeds pellets for about 1 minute before shutting down. I installed stove about 12 years ago it is vented straight up chimney 4" with cap about 16'. I tried jumping the POF and the High Limit with no changes. I checked the hose on the vacuum switch and it is clear I also pulled it and lightly sucked on it and can hear it click. The exhaust fan was replaced 2 years ago and is clean and functioning. The door gasket looks good and I get a good flame. I did get it to run once after repeatedly turning it back on but when I shut it down 3 days later to clean it would not start again. I am at a loss it has always ran well any help would be appreciated.
