Replaces / Cross-Reference Part Numbers

  • Replaces any start capacitor with the same capacitance, voltage, and physical specifications.
  • Generic Model Type: CD60
  • Cross-references part numbers such as 6501038 and 7525353.

Compatibility & Fitment

  • For use in single-phase electric motor starting circuits.
  • Commonly used in HVAC units, air compressors, pool pumps, well pumps, and other electric motors.
  • To ensure compatibility, the replacement capacitor's VAC rating must be equal to or greater than the original part.
  • The capacitance (µF/MFD) rating must match the range specified for the motor.

When to Replace

  • Motor hums or buzzes but does not start.
  • Motor starts slowly or requires manual help to turn over.
  • The original capacitor shows physical damage, such as bulging, cracking, or leaking fluid.
  • A multimeter test shows the capacitor is outside its rated capacitance range.

Installation Tips

  • Disconnect all power to the equipment before servicing.
  • Discharge the old capacitor by safely shorting its terminals with an insulated screwdriver.
  • Note the wire placement before removing the old capacitor.
  • Confirm specifications of the new capacitor match the motor's requirements.
  • Secure the new capacitor with the original mounting hardware.

FAQ

If your air conditioner or motor hums but fails to start, or if the motor struggles to reach full speed, the start capacitor is often the culprit. Other signs include the motor tripping the circuit breaker immediately upon startup or a noticeable burning smell coming from the capacitor housing.
Yes, this unit is a universal replacement that cross-references with various industry part numbers, including DiversiTech T161-193220, C161E250, and 091A161B250CE7A.
Always inspect the motor's start switch or relay. If the start switch is stuck in the closed position, it can cause a new capacitor to fail prematurely. Additionally, ensure the power is completely disconnected and the old capacitor is safely discharged using a resistor or insulated screwdriver before touching the terminals.
Replacing a capacitor is a straightforward task that typically takes 15 to 30 minutes. You will generally need a screwdriver to open the access panel and a pair of needle-nose pliers to disconnect the spade terminals. Ensure you note the wire positions or take a photo before removing the old unit to ensure the new one is wired identically.
This round start capacitor measures approximately 4 3/8 inches in height and 1 13/16 inches in diameter. It features two posts with two terminals per post, making it compatible with most standard HVAC and compressor motor configurations.
