I have a Bryant gas furnace, model# 310AAV048135. It comes on, runs for a couple minutes then shuts off while the blower still runs. I am getting a fault code of 33, which indicates several things according to the label on the device. Earlier in the summer, I was having a similar problem when the AC runs it was cycling too often and the service tech said the Draft Safeguard Switch could be faulty, since he could not find an obstructtion in the vent. It was not real bad, so I didn't do anything at the time. Now with temps reaching sub-zero, it seems to be more of a problem. Is there anything I can do to fix this without an expensive service call? Or is this something which needs the attention of an expert?

Gee I wonder what those codes are saying?

I understand what the codes are saying. That was not my question. I was simply asking if the Draft Safeguard Switch was something that a common layperson could order and install themselves.

I believe this was the question

The reason I asked for the code meaning and posting exactly what it said is that I cannot remember what all the different brands and model codes mean and it is hard to answer your question exactly without the exact information.

Now if you want to start replacing parts go for it. I feel you could replace any part on that furnace if you wanted to but that part may not fix the furnace since it may not be the correct part to start with. That was the reason I asked what the code stated so I could have a better look at what the computer board was actually saying.

Sorry I tried to help you and I feel you just want someone to agree with a decision you already made. I usually look into problem a little more in depth rather than just start throwing expensive parts at the problems. Any service hack can replace parts. Good Luck with your repair.

Sorry, hvac1000. Guess I took your first comment as flippant and I did not understand that you were asking me for clarification of the codes. No worries though. I will just call out an expert instead of trying to work on things I have no expertise in. Thanks for your comments.

That would probably be your best bet. We have to try and answer questions without all the info we need and sometimes that is imposible to do.
