I HAVE A LENNOX G16 FURNACE AND REPLACED THE INDUCED DRAFT BLOWER. NOW THE WHOLE HOUSE VIBRATES WHEN THIS IS RUNNIG. THE MOTOR SEEMS TO BE RUNNING HEAVY AND VIBRATES THE STACK. THE OLD BLOWER, A BEARING WENT IN IT AND IT CLANGED A LITTLE BUT THAT WAS BETTER THAN THIS VIBRATING NOISE, YOU CAN FEEL THE VIBRATION IN THE FLOOR AND WALLS. IS THIS NORMAL? PLEASE HELP.
No it's not normal. Vibrations can cause seperations of the smoke pipe joints if they are not secured with 3 zip screws. Normal operation of these motors can be heard, but excessive noise and /or vibration should be addressed. Re-check your mounting application. Compare the amperage of the old motor to the new one.
