MARS 11927 Start Capacitor
The MARS 11927 Start Capacitor is a heavy-duty, electrolytic component engineered for intermittent AC motor starting applications across the HVACR spectrum. Rated for 590-708 Microfarad (MFD/uF) at 110/125Vac, this round capacitor is housed in a rugged, moisture and oil-resistant black Bakelite case. This phenolic construction is designed for professional-grade durability, protecting the internal elements from grease, dirt, and harsh mechanical room environments. As a veteran-preferred HVAC start capacitor, it provides the necessary torque boost to compressor and blower motors during the initial 75% of acceleration before the run circuit takes over.
For technicians performing field service, the MARS 11927 is a reliable motor start capacitor replacement that complies with Electronic Industries Association (EIA) standards. Its compact round start capacitor geometry allows for seamless installation in tight control boxes where space is at a premium. With standard 1/4-inch dual blade terminals and a wide operating temperature range of -40°C to +65°C, this 590-708 MFD capacitor ensures consistent startup performance in high-demand refrigeration and air conditioning systems.
Key Benefits for Contractors- High Torque Support: Provides a robust 590-708 MFD range to overcome high static pressure or non-bleed TXV startup resistance.
- Industrial Protection: The hermetically sealed Bakelite housing prevents premature failure due to oil or humidity.
- Universal Compatibility: Standardized physical dimensions and terminal configuration make the MARS 11927 an ideal cross-reference for most 125Vac motor start applications.
- Reliability: Engineered for up to 20 starts per hour, helping maintain system efficiency without stressing motor windings.
- Can I use this if my old capacitor is 600 MFD? Yes, the 590-708 MFD range covers a 600 MFD requirement as long as the voltage rating is at or below 125V.
- What causes these capacitors to fail? Excessive starts per hour or a sticking potential relay that keeps the start capacitor in the circuit too long will cause the relief port to open or the case to bulge.
- Does the shape matter for performance? While the round capacitor shape must fit your mounting bracket, the electrical capacitance and voltage are the primary specifications for motor compatibility.
