The LiftMaster 30B532 Capacitor is an OEM replacement start capacitor rated at 53–64 MFD (microfarads) for select LiftMaster and Elite single-phase AC operators. Used to deliver the surge of torque needed to start the motor under load, this component helps restore consistent opening and closing performance when an original start capacitor has weakened or failed. Typical listings for this part specify 220–250 VAC working voltage for 50/60 Hz applications, making it suitable for a range of residential and commercial gate operators and certain AC-driven commercial door operators that call for a 53–64 MFD start capacitor.
This replacement part installs in the operator’s control compartment and connects inline with the motor’s start circuit; it is non-polarized, so lead orientation is not directional, but each lead must return to the same terminals as the original. Always disconnect power before servicing and discharge the old capacitor safely, as stored energy can remain after power is removed. For compatibility, match by part number (30B532) and by electrical rating (53–64 MFD, 220–250 VAC) as specified in your operator’s manual; use only on units that explicitly list this value to ensure proper motor starting and long-term reliability. Common search terms include LiftMaster 30B532, 53–64 uF start capacitor, gate operator replacement part, and AC motor start capacitor for LiftMaster/Elite operators.
