    Bryant plus 90 350mav code 34/14
    I have a Bryant 350mav that is giving a code 34 followed by a code 14 . I checked the intake and exhuast pipes and they are clear. What next? It is blowing cold air, cycles the 3 times and then locks again.

    34 - ignition proving fault. 14 - ignition lockout. Check the service label inside front panel. Probably a dirty flame sensor. Remove and clean it with abrasive cloth or steel wool. Located on bottom-left of burner box (if upflow configuration), held by a single screw and has a single white wire connected. If intake pipe comes out left side, you may have to disconnect it to access.

    Observe ignition - do all the burners light? If only some, may need cleaning. If none, remove burner box cover and try again. If this works, the ignitor gasket may be bad. Ok to run with cover off short-term.

    Had the same 34 code on my Bryant 355MAV. Turned out the ignition filament wasn't glowing. Took it out and cleaned it. Put it back in now everything works
