    I troubleshot a control box for a 1hp(suposed) submersible pump that showed the capacitor was shot. i tried to find a replacement but it was to old so i replaced the whole control box. the water came on and stayed on for aprox. 2 min. and the pump shut off. when i switch the lever to on i hear the control box hum like normal but the pump does not come on. Help??

    If the control box is 'so old' then how old is the pump? Older than a decade makes the pump a candidate for replacement.

    Either you have too small of a control box, or the pump is connected to a pressure switch and is actually coming up to pressure, shutting off and functioning correctly.
