The run capacitor in your ac is used to store energy which is used to turn the fan motor an essential component to your working ac. In contrast the start capacitor specifically provides the energy needed to start up your air conditioner. How To Check Motor Start And Motor Run Capacitors Motor Start Capacitors Vs Motor Run Capacitors West Capacitors Series And Parallel Hvac School This capacitor contains a higher capacitance than a run capacitor. Run capacitor vs start . As you might expect it takes more torque to start the motor than to keep it running so the capacitance that is the energy storage capacity of a start capacitor must be higher than that of a run capacitor. Start capacitors ratings of 70 microfarad or higher have three voltage classifications. The start capacitor generally has more capacitance than a run capacitor the 7 to 9 microfarad capacito...
