I am actually working on an old pool heat pump so the make and model won't help (nothing available online). Often what happens in an A/C unit is one side will fail while the other is good, so a tech will simply wiring a single to replace the bad side. Normal single phase motor does not produce revolving torque to overcome this problem two windings are done which requires two phase supply also. You need to replaced the capacitor with either a 7.5 MFD to get the life of A the motor and B the capacitor.
