    Does a super boost work w/ start & run capacitor?

    My compressor will not start. The start capacitor was replaced. I was reading about a super boost. My system has both a start & run capacitor and a delay relay all build in.

    Since a super boost can/will have a delay relay built in it. Will this help to start the compressor?? I realize the compress or is old.

    you need a new compressor, if the start cap and relay are good

    I was thinking the same thing. If you really need a super boost, maybe it's time for a new compressor.

    A hard start capacitor increases compressor torque; I won't go into how or why. (Read up on how single phase induction motors work)

    Yes, installing a product such as superboost or full hard-start kit can extent the lifespan of a compressor by several years. Note that I said can, not will.

    It's dead Jim.
    If more government is the answer, then it's a really stupid question.

    It can also reduce the life if the compressor is not really the problem, Those heaters can leave the start winding energized too long. But if it's that or replace the compressor it's worth a shot.

    Not that this thread belongs in an open forum, but what the heck.

    I have used two start capacitors and whacked compressors with boards to get them started. Some died right then and there and some started and ran for a while longer.

    If a compressor hums at all, I will either get it to sing or kill it completely. Then again, I am a professional

    Hard start kits

    Put the Hard start kit in parallel to the run cap and remove the existing start cap and relay. This should (if windings not to bad of shape) help give some life to the compressor - Remember Caps act the opposite as resisters (as far as the capacitence value figured) in a circuit - adding a hard start kit to (in parallel or series) the same start circuit will either be too much uf or not enough (both cases spell burnout of circuit - overheat). Simply let the hard start kit take the place of the existing (removed start circuit) by putting it in parallel with the run cap. Hope this works for you. Good luck! Oh... and you will be replaceing the compressor in the near future so start a compressor fund.

    Make sure your run cap is good also.

    You already have what amounts to a "Super-boost" in your existing start cap.

    Reasonably you should be able to to just put a larger start cap in to get the same results.

    But you run the chance of over heating the start winding by doing so.

    My advice would be to have the compressor "Megged" this will tell you the condition of the winding resistance and insulation value. From this you can garner a better idea of your comp general state of health.

    God luck.
