Hi, thanks in advance for reading this . Had my stove tuned up a couple of weeks ago, called the dealer the day before to let them know I needed a vac switch, they said no prob. They showed up(stove was confirmed warm and had been running fine prior to their arrival) they did their thing, and stove would not power up, control panel dead! They said it was not their fault and walked... I replaced the control board and vac switch myself and stove powered up, no problem..ran a few mins but never lit...comb blower jammed error, snap disk is ok (had continuity thru it, so assume its closed and ok) area inside was vacuumed and is clean, no obstructions. Repleaced the comb blower, still getting the comb blower error. Any ideas before I replace the stove? Thanks much for any input!!
