Defective Condenser Fan *

[HarryB]

The condenser fan motor on my heat pump won't run although it spins freely when pushed by hand.

Checking the resistances of the windings reveals the following -

Common to Start (C-S)- 163 ohms
Common to Run (C-R)- 73 ohms
Run to Start (S-R)- 89 ohms

My online browsing indicates that the sum of the resistances of (C-S) and (C-R) should equal the resistance of (S-R), but this obviously isn't the case.

Should I assume that the motor needs to be replaced (the capacitor seems to be OK)*

TIA,
Harry
