Comfortmaker furnace
When my furnace performs great, except maybe once a week.
It appears it goes thru its cycles alright untill the end. After the burner shuts off, the main blower continues to run, even after the chamber is cool. If I cycle the power it comes back on and works normally. Any Ideas?

Would it be possible Duane for you to post a picture of your furnace with both doors off? That way I can see what type of fan control you have and better direct you on your next step. Thanks!

I have attached the pictures you were looking for. I did encounter one problem when I took off the top cover. I accidently bumped the flame roll out switch, which broke. I will have to replace that. I jumped that to get me thru the night. Thank you

If the filter is clean, then the fan relay that is imbeeded on the board is going bad, you will have to replace the board......I have on identicle one that you have here in stock, and I cant ship the same day that payment is made . I have secure paypal. and the board is very easy to change out, wire for wire.The cost on that board is $150 and that includes shipping. One other thing I am going to the bristol race and then on to florida this weekend and I wont be back untill next Friday but if you pay before 3 pm est I can still ship it today.
