Short, intermittent alarm.

[SeanT]

Hey Roger,
Can't find my manuals so I need to bug you.
One of my streams lets out an alarm about .5 seconds in length and happens randomly.
My streams were cleaned fairly recently.
Is that it or is there another possible reason?
Thanks,
Sean

Hi SeanT,

If you have followed all the cleaning procedures outlined in the thread at the top of this forum you may need to send it in to Roger for repair.
Unless Roger has another suggestion.

Best Regards
Graeme

Hey Sean,

I would suspect that the upper bearing is worn or sticking to the magnet, the center hole in the magnet is plugged with calcium or the bearing bush is loose and needs to be pushed back in.

I just got around to taking them all out and giving them a cleaning of a lifetime.
They are still chirping.

Could having them on a multi-controller, with the varying speeds, have any effect?

Sean, is just one chirping or more than one? The controller could have an effect and I recently heard from someone that an electronic ballast was the culprit with the chirping they had from the driver box.
