In this video zack psioda explains how many dual run capacitors are wired in heat pump and. How to replace an old "dual" capacitor? [citation needed], Some single-phase AC electric motors require a "run capacitor" to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running. About 78% of these are capacitors. When testing a run capacitor many techs pull the leads off and use the capacitance setting on their meter to test the capacitor. jgregorylaw.md-wv.com I'm guessing there's actually 2 capacitors inside that cylinder of 450V/40MF each, cross connected in some fashion. If the switch is always open, the start capacitor is not part of the circuit, so the motor does not start.
