I have a Bryant Plus 80 that is throwing a error of 33 (limit or flame roll out switch is open). The last time this happened was because the hot surface igniter was broken (frequent problem as my furnace has a tendency to short-cycle). I had picked up a couple extra ones so I had them on hand to replace. Nothing. Still flashes 33. I know there are manual reset buttons, but I only found one at the very top of the furnace, and that didn't reset anything that I could tell. The wiring diagram imprinted on the furnace cover says that the resets are inline with a red wire, but I traced the whole wire and it is just a wire. I checked a manual online, but it didn't quite match my furnace (ie- there is nothing where they said a reset should be, and the schematic is backwards to what mine is). I did disconnect the power for about a half hour, and that didn't reset it either. So now I am really kind of stuck here and any help or advice would be appreciated!
