I did a big cleaning on my stove the other day and ripped the gasket that goes between the fan and the housing. My stove will sometimes run for days then shut down with the #2 blinking. Now it runs only a couple hours or minutes before shutting down. I ordered a new gasket from Breckwell for $4.95 +$15 shipping and I hope it comes in soon. I think I cleaned everything on this stove from the chimney cap down to the little tube that has the vacuum sensor. Will the torn gasket cause the #2 error and if so why is it so unpredictable??
