Discuss Classic ff360 high pitched whining in the Central Heating Forum area at PlumbersForums.net

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?
