I have a Bryant 350MAV, just replaced defective blower motor (siezed up) and now the furnace starts to produce heat and after a few minutes the burners shut off and I get a fault code 33. What do I do??

Code 33 is a limit circuit fault. Most likely, the furnace is overheating for some reason. Is the replacement motor OEM or aftermarket? If a universal aftermarket motor was used, was the rotation set correctly? If running backward, inadequate airflow will cause overheating. Check page 15 of the attachment for other possibilities.
Thanks, I found that the new motor was in fact running backwards, causing the furnace to overheat. I switched the motor to the correct rotation and everything is fine now
