• Tolerance: ±5%
• Voltage Rating: 370 VAC / 440 VAC
• Frequency: 50/60 Hz
• Shape: Oval
• Construction: Oil-filled aluminum case
• Safety: Protected to 10,000 AFC
• Operating Temperature: Meets industry standards from -40°C

Replaces / Cross-Reference Part Numbers

This component replaces any brand of single-value run capacitor with the following specifications:

• Capacitance: 7.5 uF/MFD
• Voltage: 370V or 440V
• Shape: Oval

A 440V rated capacitor can be used as a direct replacement for a 370V rated capacitor. The physical dimensions must also match for proper fitment.

Compatibility & Fitment

Designed for continuous-duty motor run applications, including:

• Air conditioner condenser units
• Heat pumps
• Furnace blower motors
• Compressor and fan motors
• Pool pumps
• Refrigeration systems
• General purpose single-phase motors

When to Replace

A run capacitor may be failing if you observe the following symptoms:

• Motor hums but fails to start or starts slowly
• Fan blades require a manual push to begin spinning
• AC or heat pump compressor does not engage
• Visible damage to the capacitor case, such as bulging, swelling, or fluid leakage

Installation Tips

• WARNING: Disconnect all electrical power to the equipment before servicing.
• Capacitors store a potentially hazardous electrical charge. Safely discharge the old capacitor by shorting its terminals with an insulated-handle screwdriver.
• Document the wiring connections before removing the original part.
• Verify the uF/MFD rating of the new capacitor matches the original exactly.
• The voltage rating of the replacement capacitor must be equal to or greater than the original.
• Confirm the physical dimensions will fit securely within the mounting bracket.
