• Heil HQ1086678AX
• CBB65-440R0335

Compatibility & Fitment

• Designed for dual motor run applications to power a compressor and a fan motor.
• Used in HVAC systems, central air conditioners, heat pumps, and condenser units.
• Compatible with systems requiring either a 370 VAC or 440 VAC capacitor.

When to Replace

• Compressor or fan motor fails to start.
• A humming sound is audible from the unit without the motor engaging.
• Existing capacitor shows physical signs of failure such as bulging, cracking, or leaking oil.
• Measured capacitance is outside the specified tolerance range.

Installation Tips

• Disconnect all electrical power to the unit before beginning work.
• Safely discharge the old capacitor by shorting the terminals with an insulated tool.
• Note the wire placement on the old capacitor's terminals (C, FAN, HERM) before disconnecting.
• The new capacitor's MFD rating must match the original.
• The new capacitor's voltage rating must be equal to or greater than the original.
