Compatibility & Fitment

• Designed for starting and running single-phase AC motors.
• Commonly used in air conditioning units, heat pumps, condenser units, and furnace blower motors.
• Serves both the compressor motor (50 uF) and the fan motor (10 uF) in a single component.

When to Replace

• Motor hums but does not start.
• Fan runs slower than normal or needs a manual push to start.
• Compressor fails to engage.
• Visible signs of damage such as bulging, cracking, or leaking fluid from the capacitor case.
• Capacitance measures outside the specified tolerance range when tested.

Installation Tips

• Disconnect all power to the equipment before beginning work.
• Safely discharge the existing capacitor by shorting across the terminals with an insulated tool.
• Verify that the voltage and microfarad (uF) ratings match the original capacitor.
• Note the wire placement on the old capacitor's terminals (C, FAN, HERM) before disconnecting.
• Ensure all wire connections are secure before restoring power.
