• Stabilizes voltage supply to extend the service life of blower motors and compressors.
• Compatible with a wide array of Nordyne equipment, reducing diagnosis-to-repair time.
• Reliable performance in systems requiring a 370V AC capacitor, ensuring stable start and run torque.

Common Questions

Can I use a capacitor with a higher voltage rating than 370V?
Yes, in modern HVACR practice, a 440V capacitor can typically replace a 370V unit, provided the microfarad (MFD) rating matches exactly. However, a 370V capacitor like the 01-0021 should not be replaced by a lower-voltage unit.

What are the symptoms of a failing 5 MFD run capacitor?
Technicians often encounter humming motors that fail to start, motors overheating, or units drawing higher-than-rated amperage. A physical inspection may reveal bulging at the top of the canister or leaking dielectric fluid.

Is this capacitor used for the compressor or the fan motor?
A 5 MFD rating is most commonly found on condenser fan motors and small blower motors. Always verify the MFD requirement on the motor nameplate or the original capacitor before installation.
