The Start Capacitor gives a fan motor the torque it needs to start spinning then stops, while the Run capacitor stays on, giving the motor extra torque when needed. Thank God my pump was Okay. What causes compressor capacitor (single) to fail 5 times in 9 years? So, its the contactor actually powering up this capacitor, and the way its charged is from current flowing from T2 at the contactor, to the c-terminal on the capacitor. I would have expected that to make the fan not start up. I always hear people calling it a dual run capacitor, that is where the confusion comes in. I have seen online somewhere that some fans (OFM) do not need a capacitor to start and run. An AC capacitor provides the initial jolt of electricity your air conditioner's motors need to run successfully. Could my issue be the run cap that the motor is connected to or could there be another issue I should look into? I doubt it.

One way to prolong the inevitable and that would be cost effective versus purchasing a new system would be to install a hard start kit. In other words the internal high amp cut out will be engaged and therefore no electricity / electrons should be engaged at the capacitor. My a/c was not working, the last time the repair man can out all he did was re-connect the dual run capacitor and then next year we tried using the a/c but it just wasnt getting cold, sounded like the fan was only coming one. 90 / Piece. Information. They both go back up into the fan motor, Maybe we Gordon people how to discharge a capacitor and to treat every capacitor as a live capacitor before you have people handling a 440 volt AC capacitor with their bare hands, Mines well just hand them Smith & Wesson or Glock 45 and tell them to point it at their faces and hope for the best. We're Here To Help: 561-989-8080 I am holding off on replacing the blower motor at this time. It would be like flooding a gas engine.
