Problem: What is the sequence of operation of my gas furnace?
Answer: Below we have a very good YouTube Video made by Grayfurnaceman.com which explains the sequence of operation for an 80% Goodman gas furnace. We hope this will help answer your questions. I could not have explained the sequence of operation any better than Grayfurnaceman.com. Thanks to Grayfurnaceman.com for making this YouTube video. We will be glad to answer any of your questions either through our email: firstname.lastname@example.org or in the comments section near the bottom of this page. We hope you have a blessed day!
