SUCK TEST worked. With the house quiet I could hear the mechanism click when I gently pulled a vacuum on the tube. So I got my compressor from garage and disconnected tube from vacuum switch and connected tube to nipple/barb up on auger housing. I blasted compressed air through that tube multiple times and for longer duration than I could ever do by mouth. Reconnected everything and turned stove on. Same issue. No auger. Then I thought to cover the air-wash opening along the top of the glass door. BINGO. I got suction enough to trip the switch and start the auger. As long as I covered that airwash edge along top of door the stove worked fine. So, when I replaced my gasket months ago I was getting sufficient vacuum. Maybe now that the gasket has set and been through many burn cycles I have lost vacuum? I have the tadpole gasket along 3 complete sides of the rectangle on the door. Two short sides and one long. The top is open to keep the glass somewhat clean I assume. Should there be more gasketing across the top? Can somebody with a Castile perhaps post a picture of their tadpole gasket? Much appreciated. Now to call and see if I can cancel the order for the new vacuum switch.
