MARS 11982 Capacitor
When you're troubleshooting a compressor that hums but won't kick over, a weak or open 710-852 MFD motor start capacitor is the primary suspect. The MARS 11982 is a field-proven 165V start capacitor designed specifically for heavy-duty HVAC motor starting applications. This round, electrolytic unit provides the high-torque boost necessary to overcome back-pressure in single-phase systems, particularly those using non-bleed TXVs. Built with a rugged, moisture-resistant Bakelite case, the MARS 11982 protects internal components from oil, dirt, and grease in the harshest equipment environments. Technical upgrades to the dual blade terminals allow for superior heat dissipation, making it a reliable choice for AC capacitor replacement in high-humidity regional installs. For veteran techs, this 710-852 uF capacitor is the go-to stock item for restoring compressor starting torque without the fluff of marketing-heavy alternatives. Ensure your potential relay is functioning correctly to prevent premature venting or membrane failure.
Key Benefits
- Enhanced Starting Torque: Effectively bridges the gap to 75% motor speed before the potential relay cycles the unit out.
- Industrial Durability: The hermetically sealed black Bakelite housing resists environmental contaminants and high-ambient heat.
- Universal Physical Profile: Compact 1-7/16" diameter and 2.75" height ensure compatibility with standard motor control boxes.
- Reliable Terminations: Integrated dual-blade 1/4" male terminals are engineered to minimize resistance and heat generation during the start cycle.
Common Questions
Can I use a higher voltage capacitor if a 165V unit isn't available?
Yes. In the field, you can substitute a higher voltage rating (e.g., 250V) provided the MFD stays within the 710-852 range, but never use a lower voltage rating than specified.
Why did my previous 710-852 MFD capacitor fail?
Failure usually stems from a sticking relay or short cycling. If the capacitor stays in the circuit for more than a fraction of a second, the electrolyte will overheat and blow the top membrane.
Does this capacitor come with a bleed resistor?
Standard replacement start capacitors often do not include a pre-installed resistor. For safety and relay protection, it is best practice to field-install a 15,000 to 18,000 Ohm resistor across the terminals.
