  • Kaussmann heat pump.

    From [email protected]@21:1/5 to All on Sat Feb 10 20:53:39 2024
    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
    news client here.

    Thx, ... P.

    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.
