Suburban furnace very noisy
Hi, happy to be here, my first post, have a Suburban SF-30F, removed and checked for loose fan, everything nice and tight the only thing I thank may be causing all the noise was a Metal mount attached...

Does the fan spin freely using finger or straw? I use a straw with power connected, disconnect power if using finber. Check for power to ground at circuit breaker on both in and out terminals.
Did you wedge fan with pipe insulation?
Motor bearings go bad and make noise as fan hits housing.
