I have Amana Air Command 80. I turned it out and it is not forcing the air. When i turn it on the sensor heats up and gas does ignite but forced air fan does not come on. After about 15 to 20 seconds it starts to recyclo.

Hi all, First time here and all. Is cleaning a Anderson ultra 80 lowboy heat exchanger as easy as the 2 page "sales guide" show's where you sweep the 2 chambers with a stainless steel bottle brush? It seems WAY too simplistic to me and all. I have replaced the furnace oil and air filters, the nozzle, and set the electrode gap with the beckett T 501 gauge so I think all that is good to go. The furnace ran excellent last two heating seasons and didnt have anyone service it since fall of 2009. The 3 local technicians I checked into for having them do the work are 2-3 weeks behind so I did all the above work this year as I was having heating problems. Now I just wonder about the heat exchanger and my efficiency with it not being cleaned in over two years now. Match test and all that come out excellent and my overfire draft is correct at about -.02 inches. Thanks for any assistance you can provide.
