    Our central heater is sounding very loud when the heat comes on. The main recirculating fan is okay. The small furnace fan connected to the exhaust pipe is rusted and makes a loud (grinding, slightly vibrating) noise when the heat comes on. Anyone else experienced this? My thought is that the rust is causing the grinding, loud sound? Can this become a problem? Any advice/recommendations? Thanks in advance for your input......

    I believe there is another fan that is used just for the heat... the inducer motor that blows out to the vent. My guess is your problem is that fan and its operation. You might have a condensation build up problem too contributing to the rust situation.

    It is something someone could replace themselves if they sourced the parts.

    Yea I had a problem similar to this as well... the inducer motor and fan was not working. When checking... I manually spun the fan and realized that a piece of metal was in there blocking the fan from moving. But that fan and motor can be replaced and it seemed like a fairly straightforward process.
