My pleasure. I’m glad I was able to help!This post might have just saved me $400... I've been having the same problem all summer. Replaced all the switches, was determined the fan isn't the problem, and was about to break down and order a Fireboard 2. Instead I bypassed the ash pit switch as indicated here. Just a test run so far - the real proof will be a full cook, but so far operating perfectly. Thank you so much!
