Nordyne 01-0023 Run Capacitor

The Nordyne 01-0023 Run Capacitor is a critical electrical component engineered for precise load leveling in forced-air systems and condensing units. This 7.5 MFD 370V round run capacitor provides the necessary phase shift for motor windings, ensuring high power factor efficiency and stable torque during continuous operation. As a genuine OEM HVAC replacement part, it is the specified substitute for legacy part numbers 621434, 622132, and 622132R. Maintaining the correct microfarad rating is essential for preventing motor overheating and premature winding failure in Nordyne furnace and AC units. Built to withstand high-ambient temperatures common in electrical service panels, this 370 VAC capacitor ensures your blower motors and fans maintain consistent RPMs. For technicians servicing Miller, Intertherm, or Broan equipment, utilizing the Nordyne 01-0023 ensures the system remains within factory-specified electrical tolerances, protecting the compressor and fan motor from irregular current draw.

• Direct OEM Match: Drops into existing mounting brackets with a standard round run capacitor form factor, eliminating the need for strap modifications.
• Cross-Reference Compatibility: Replaces obsolete Nordyne 621434 and 622132 series components without altering electrical performance.
• Verified Capacitance: Rated at 7.5 microfarads (uF) to maintain the exact magnetic field required by permanent split capacitor (PSC) motors.
• High Voltage Threshold: Rated for 370Vac, providing safe operation for standard residential and light commercial HVAC circuits.

Can I use a 440V capacitor if the 370V is out of stock?
Yes, you can substitute a higher voltage rating (440V) for a 370V unit, provided the capacitance (7.5 MFD) and physical dimensions are identical. Never install a capacitor with a lower voltage rating than the original.

What symptom indicates this capacitor has failed?
Typical signs include a humming motor that fails to start, an outdoor fan spinning slowly, or the capacitor casing showing physical bulging or leaking oil. Using a multimeter to check for 7.5 microfarads is the standard field test.

Why is the OEM dual-run or single-run rating important?
The Nordyne 01-0023 is a single-value capacitor. If your unit requires both a fan and compressor start, ensure you aren't overlooking a necessary dual-run configuration, though this part is frequently used as a dedicated fan capacitor.
