How many PF100 or PB105 owners have had igniter failures? For the PB105 owners this does not include the pressure igniter system. I’m talking about the igniter under the burn pot type ignition system. I’m just winding down my second winter heating season and have just had my second igniter failure. The first winter 2008-2009, the igniter failed right around this time of year as well. I’m thinking that as the temps moderate, the furnace shuts completely down between calls for heat. This requires the furnace to do a cold restart several (or more) times a day as opposed to winter operation where it hardly ever shuts down. These repeated restarts seem to be killing my igniters. Are any other owners experiencing this?
