AFCI nuisance tripping or an actual problem? : r/electricians
The way that motor works is that there is a capacitor that is used to make it spin in the correct direction, then once it gets to about 75% speed, a centrifugal switch on the motor opens up and cuts out the capacitor. Opening that switch creates an arc and the AFCI breaker is SUPPOSED to filter that out, but sometimes it doesn''t and it trips.

[AC] Replaced capacitor, now unit tripping plug breaker?
Run capacitors do not hold a charge when the compressor is off, they discharge themselves through the motor windings of the compressor. When not in the circuit, a motor winding is just an electric resistor. If you get shocked by a run capacitor or it ever does have a spark then there is usually something wrong with the motor it''s hooked up to.
