Hi,

A friend has a Kaussmann heat pump in her home.
It produces a noticeable but not loud whine.

Heated air is dispersed by a centrifugal fan with squirrel cage about
80 cm long x 9 cm diameter. The blades are about 1 cm wide and 10 cm
long. 10 cm x 8 segments = 80 cm.

One of the blades is missing from the rightmost segment of the
squirrel cage and that may be the source of the whine.

According to the owner, Kaussmann is defunct. Any ideas about repair?

Thanks, ... P.

Thanks Jim.

Apology for my duplicated message. I had a bit of trouble with the

That missing blade might be correct. It could be that
there is a set screw holding the squirrel cage assembly
to the fan motor shaft accessible where (and because)
the blade is missing. I'm speculating, not sure.
