Nordyne 01-0278 Run Capacitor

The Nordyne 01-0278 Run Capacitor is a high-performance OEM dual run capacitor engineered for precision in Nordyne, Miller, and Intertherm HVAC systems. Rated at 70/7.5 MFD 370V, this component provides the essential phase shift required for both the compressor and condenser fan motor. Utilizing a round, oil-filled metal canister design, it is built to handle high ambient temperatures and demanding duty cycles common in residential split systems and packaged units. As a direct HVAC replacement part, it ensures the motor windings operate within designated electrical parameters, preventing overheating and premature failure. Using a 70+7.5 uF capacitor that meets original equipment manufacturer specs is critical for maintaining the Power Factor and overall efficiency of the refrigeration circuit. This dual run capacitor for AC units features standard 1/4-inch male quick-connect terminals for a secure, low-resistance connection during field installation.

Key Benefits:

• Direct OEM Integration: Exact match for Nordyne 01-0278 ensures correct physical dimensions and mounting bracket compatibility.
• Dual-Motor Support: Consolidates the 70 MFD compressor capacitor and 7.5 MFD fan capacitor into a single space-saving round housing.
• Voltage Tolerance: Designed for 370 VAC applications, providing stable capacitance under fluctuating line voltage.
• Extended Component Life: Proper microfarad output reduces amperage draw, protecting motor windings from thermal stress.
• Critical Safety Standards: Includes internal pressure-sensitive interrupter to safely disconnect the capacitor at end-of-life.

Common Questions:

Can I use a 440V capacitor to replace this 370V model?
Yes, you can upgrade to a higher voltage rating (440V), provided the capacitance remains exactly 70/7.5 MFD. You must never use a capacitor with a lower voltage rating than the original.

What are the symptoms of a failing 70/7.5 MFD capacitor?
Common indicators include the compressor humming but failing to start, the outdoor fan motor spinning slowly or not at all, and audible clicking from the contactor.

Does the orientation of a round capacitor matter during installation?
While the capacitor can be mounted in various orientations, ensure the terminals are protected from moisture and the casing is securely fastened within the electrical cabinet to manage vibration.
