I have an older Mt Vernon pellet stove. It's been giving me fits and won't start up. I cleaned it all out the last time like I normall do when it starts giving me issues. Pull the inside panels all out and vacuum behind the panels and by the heat tubes and clean things all up. Did this and wouldn't start. It will flash a blue light once every 10 seconds or so on start up. It will start dropping pellets but then no ignition. Bought another igniter off of Amazon which I'm sure isn't the best place but it was over the weekend. Took the old one out and had to splice the wires as that's how the old one was. Old igniter had no resistance after testing the two leads. Tried it again and goes through the same sequence of not igniting but will flash the blue light once every ten seconds and start dropping pellets. Even pulled the vacuum tube off and verified it was clean and also cleaned out the port where it plugs in by feeder tube. I'm at a loss. This stove has always served us well but I figured it was time to call the experts. Even bypassed the thermostat and jumpered the two wires to eliminate that out of the equation.
