My blower fan will not come on. Bryant high efficiency furnace (approx 12 yrs old).

I'm getting the 33 code on the LED, which means: limit or flame roll out switch is open. I've hit the re-set on the flame roll-out but, the blower still does not turn on.

Any advice here?

Could be the control you reset is defective. Just because you reset it does not mean it is good. Test it with a meter.
