Run Capacitor — 370/440V, Round — manufacturer part number 203020 .
What this part does
The run capacitor stores and releases the electrical charge that keeps your compressor and condenser fan motor turning. When it weakens, the motor cannot start or hold speed, which is why a failing capacitor is the single most common air-conditioning failure.
Replace this part if
AC hums but the fan does not spin
Outdoor unit trips the breaker on start-up
Capacitor top is domed, bulging, or leaking
AC starts, runs briefly, then shuts off
Fan spins if you push it with a stick, but not on its own
