Classic ff360 high pitched whining

[Dickieh]

Hi

Classic ff360 makes intermittent high pitched whine when gas kicks in. Lasts maybe 2-3 seconds and repeats each tine gas kicks in. But then won't do it fir a day or two and then starts again.

Fan bearings lubed duribg last service but of course made no noise the day they came out! Any ideas?

Are you gas safe buddy

Yep time to get them out for diagnostics

Can’t do gas advice unless your qualified

Any ideas?

Install a recording app on your phone and record the noise the next few time it happens. Contact a Gas Safe engineer and let them listen to the recording.
