MARS 11969 Start Capacitor

As a field-tested technician, you know that a high-torque startup is the difference between a smooth-running system and a locked rotor. The MARS 11969 is a heavy-duty 216-259 Microfarad 330Vac Round Start Capacitor specifically engineered to provide the necessary phase shift for residential and commercial HVAC motor start applications. Housed in a hermetically sealed, moisture-proof Bakelite case, this electrolytic start capacitor is built to withstand the rigorous demands of frequent cycling and high-heat environments. Whether you are performing an AC repair or optimizing a single-phase motor, this component ensures your compressor or blower motor overcomes initial inertia without excessive amperage draw. Its dry, non-polarized design is rated for intermittent duty, meeting or exceeding industry standards for HVAC part replacement. Use the MARS 11969 as a reliable drop-in solution to restore high-starting torque and extend the operational life of the equipment in the field.

Common Questions

How do I know if my AC start capacitor is bad?
Common signs of a failing capacitor include a humming sound from the motor without rotation, the compressor struggling to cycle on, or visible physical damage such as bulging or leaking at the top of the terminal deck.

Can I use a 330V capacitor to replace a lower voltage unit?
Yes. In HVACR applications, you can replace a 110V, 125V, or 250V start capacitor with a 330V unit, provided the MFD range matches the motor’s specifications. You should never go lower than the original voltage rating.

Is the MARS 11969 compatible with 50Hz and 60Hz systems?
Yes, this electrolytic capacitor is designed for universal operation on both 50Hz and 60Hz single-phase AC circuits, making it suitable for a wide range of motor applications.
