Great video. Very informative. Thank you. I do have a question:: I pulled the Inducer motor assembly and the 5" diameter fiberglass gasket came off in pieces. Do I have to replace it with the same gasket or can I use a high temp. RTV silicon to make a gasket?
Thank you and that's a great question. I prefer to use the exact gasket but we know that's rarely an option. When changing commercial heat exchangers they would send high temperature gasket material so I would keep that, cut it myself and use it when needed. I'm sure the material could be purchased and kept on hand. As for the RTV red, I don't know. The heat exchanger should not exceed 170⁰F and the RTV red is rated for 600, so in theory it should work but I have never tried it.
You are amazing Ty, thanks. I've been having problems finding information on how draft and venting works on gas furnaces. Do you have any books or materials you would recommend to learn more about it?
If you can find a class from NCI National Comfort Institute, they have CO and com nation classes that go deep into the matter. ESCO has a book combustion analysis that covers it to as the draft system is directly related to combustion analysis. I also recommend CO a clear and present danger. It covers how draft from other appliances working together in the home can affect the furnace draft.
09:50, OR, go listen to the outside furnace flue pipe exit. Upon motor startup, at its lowest RPM's, before too much air flow sound is coming through, YOU CAN HEAR the tell-tale GRINDING noise of BAD BEARINGS. It is UNMISTAKABLE compared to the SMOOTH sound of new motor bearings. GRINDING NOISE is BAD JUJUBE!!
You are amazing teacher, great explanation
Thank you! 😃
Can’t wait to help out my classmates when we start learning this next semester!
Fantastic video ! Great explanation of the gas furnace heating sequence.
Great as usual Mr. Branaman. Thank you
Thank you so much for helping me grow with knowledge!!!!
He's the best 👌 hvac on RUclips
very good like usual sir

@@love2hvac terrific, thank you.
If that exhaust is negative pressure/natural draft and does not require for the Inducer to force the exhaust out. Than, what is the Inducer's job?
It's job it to pull the gas mixture threw the Hest exchanger. Very important!

How would you go about testing a 3 wire hall effect switch on a Carrier?
Here is a troubleshooting PFD for that
