Bryant Furnace NOT working

I am new to this forum and am glad that I saw this website. Anyways my problem begins with the following:

We thought we smelled gas so we called the gas company to come out and was told that the ]furnace ignitor switch needed replaced. Fast forward to October, we ordered the switch and decided to replace it ourselves. Was pretty easy I must say. However, after turning on all power and electric, the furnace comes on the switch does light but after about 2 minutes, the furnace shuts down completely. We also noticed that no heat is coming out of the vents during the duration of this process.

After 2-3 attempts, I decided to turn things off and clean the flame sensor. It wasn't really dirty at all so I basically just wiped it down with a rag and re-installed it. Started the furnace again and the same process happened.

Any ideal what this could be? Thanks in advance.

I should say that after figuring out the code, it is giving me a code 34 which means either the following:

1. oxide buildup on flame sensor-did not really notice that
2. gas valve defective or turned off
3. low inlet gas pressure
4. proper flame sense microamps-not sure what this means.

I suggest you clean the flame sensor using steel wool or light emory cloth. There is an invisible film that builds up and causes problems.
