I have a trane XE80 combustion blower hums then shuts off, do you think cleaning the flame senor would help?

Or do you think the combustion blower and maybe the pressure switch went bad?

If the motor hums and cuts out it is most likely locked or burnt. It will have to be replaced. Cleaning the sensor would not help. The pressure switch only detects air flow once the motor is running.
