Replaces / Cross-Reference Part Numbers

• Replaces any single-run capacitor with matching 120 µF capacitance and 370V or 440V rating.
• Cross-reference for CBB60 type capacitors with matching specifications.
• Potential replacement for part number 610807-002.
• Always verify physical dimensions and terminal type before ordering.

Compatibility & Fitment

• Air conditioner compressors
• Condenser fan motors
• Furnace blower motors
• Pool and spa pumps
• General purpose AC electric motors

When to Replace

• Motor hums but does not start or struggles to start.
• Fan blades or blower wheel require a manual push to start.
• Visible signs of damage such as a bulging top, leaking fluid, or corrosion.
• Capacitance measurement is outside the rated tolerance (±5%).

Installation Tips

• Disconnect all electrical power to the unit before servicing.
• Safely discharge the old capacitor by shorting the terminals with an insulated screwdriver.
• Ensure the µF rating of the new capacitor matches the original part exactly.
• The voltage rating of the new capacitor must be equal to or greater than the original.
• Note or photograph the original wire connections before disconnecting.
