MARS 11935 Start Capacitor
The MARS 11935 Start Capacitor is a high-performance electrolytic component engineered for heavy-duty HVACR motor starting applications. Rated at 233-292 MFD (microfarads) and 165V AC, this round start capacitor provides the critical torque boost required to initiate compressor and motor rotation under load. Housed in a hermetically sealed, non-conductive black Bakelite case, the unit is protected against environmental hazards such as oil, grease, and moisture, ensuring consistent performance in demanding mechanical environments. This industry-standard motor start capacitor features dual 1/4-inch quick-connect terminals for rapid field replacement and is compatible with a wide range of single-phase residential and commercial equipment. Whether you are addressing a slow-start condition or a total motor stall, the 11935 delivers a precise capacitance range to meet OEM specifications and restore system efficiency without the risk of common dielectric failures found in generic alternatives.
Key Benefits for Technicians:
- High-Torque Performance: Provides a 233-292 MFD boost to ensure reliable starting for compressors and motors.
- Durable Construction: Features a moisture and oil-resistant Bakelite housing for longevity in harsh HVAC environments.
- Universal Compatibility: Standard 165V rating and round form factor make it an ideal replacement for many major HVACR brands.
- Efficient Installation: Equipped with dual 1/4-inch quick-disconnect terminals for fast, secure wiring.
- Industry Standard: Meets professional requirements for non-PCB electrolytic capacitors used in residential and commercial systems.
Common Questions:
Can I use a higher voltage capacitor if the 165V is unavailable?
Yes, you can substitute a capacitor with a higher voltage rating (e.g., 250V or 330V) as long as the MFD range (233-292) remains identical to the original specification.
How do I know if the start capacitor needs replacement?
Common signs include a humming motor that fails to turn, a bulging capacitor casing, or if a multimeter test shows the microfarad reading has dropped below the 233 MFD threshold.
Does this capacitor require a bleed-down resistor?
While many MARS capacitors are used in circuits with existing resistors, you should check the original part. If your old capacitor had a resistor soldered across the terminals, it is best practice to transfer it or install a new 2-watt resistor to protect the starting relay.
