    Buzzing sound stays on for a few minutes when Furnace starts!!
    Hi,

    My gaz furnace is 2 years old and it was running smoothly last year. This year however, it started making a buzzing sound when it starts up. The sound stays for a few minutes and then stops when the heat as been blowing a few seconds.

    Could anyone give me advice on what this noise means?
    Any ideas?

    Thanks

    Pat

    Weak gas valve or fan relay...

    Sounds like a relay, they do this from time to time and usually is nothing to worry about. Make, age and efficiency would be helpful.
