1) Replace the belt or make sure it is tight.
2) Replace the AC compressor.

I think the resistance value of starting winding is less than the running winding of the single phase motor
The Capacitor with running winding is connected in parallel with main winding.
when the field winding of a running dc shunt motor suddenly breaks open the motor fails to run because in the motor the stationary winding is armature and rotatory is field winding
In the case of a capacitor-start/run single-phase induction motor, the main field is provided by the main (running) winding, and the capacitive branch is the auxiliary winding. In the case of a capacitor-start motor, the main winding is the running winding and the auxiliary winding is the starting winding.
start winding is thicker with less number of winding whereas run winding is less thicker than start winding but with more number of winding. As we know inductance depends upon numbers of turns of winding so run winding will have more inductance.
Starting winding has more resistance and less induction than main winding, this means has smaller diameter and less turns.
The run winding of a single phase capacitor start motor has a lower resistance than the start winding.
To create rotating magnetic field inside motor stator and it is done by capacitor. current drawn by motor running winding is lagging in nature when capacitor is connected in series with starting winding then the phase angle of running winding current and starting winding currents changes which creates a rotating magnetic field and motor is able to run.
In a motor such electric fan it needs magnetic field to operate if a coil is being energized it creates magnetism. How many speed does your electric fan has? usually it has 3 speeds so it need 3 windings and 1 for the magnetic field therefore there are 4 windings the Running winding, Starting winding, Auxiliaries.
No.
You don't have to turn the switch on the watch to keep it running.
