Noisy boiler cabinet

[gmartine]

Client is complaining about intermittent low frequency noise which she has captured on mobile but I can't recreate easily. It seems as if when the fan runs at a certain speed it induces a low level vibration in the cabinet. It's annoying when it happens but the client is cool about it, I said I'd think about it and get back to her. Boiler is a WB ri heat only, plan of attack anyone?

Everything nice and tight? Cover on properly?

Bearning plate ?

Yep.

Bearing plate ?

Not checked.

Client also said she can stop the noise/vibration if she gives the casing a slap.

A solution I have found (often) works is to place a reasonable size magnet on the inside of the cabinet. The weight of the magnet changes the natural frequency of vibration of the cabinet.

Probably worth a try
