Is this a vibration noise, or a bad bearing noise?

If it is from missing screws, you can remove a screw that you have and bring it in to home depot to match it.

My apologies, I had an appointment that I had to go to.

The noise is loud and stops when the black cylinder of the combustion blower is just touched. Does not sound like a bearing. Fan continues to run when noise stops. The noise stopped for quite a while when we put a washer where the screw was missing. It lifted the black cylinder slightly but then the noise came back after a while.

Thank you for the suggestion of finding the screw at home depot.

Should we leave the washer in place also?

If screws do not correct the problem, does the whole combustion blower housing have to be removed to replace the fan and or bearing?

Answer

If the bearing of the motor was faulty, it would require a new motor. The part in question comes in three pieces.
motor
fan
housing
