When to Replace

  • Motor hums or buzzes but fails to start.
  • Motor starts slowly or does not reach full operating speed.
  • Equipment shuts off intermittently during operation.
  • Capacitor casing is visibly swollen, cracked, or leaking fluid.
  • Capacitance measures outside the specified tolerance (±5%).

Installation Tips

  • Disconnect all electrical power to the unit before servicing.
  • Safely discharge the existing capacitor by shorting its terminals with an insulated tool.
  • Verify the capacitance (uF) and voltage (VAC) ratings match the original part.
  • Note the wire positions before disconnecting the old capacitor to ensure correct installation.
  • Secure the new capacitor in the mounting bracket and ensure all electrical connections are tight.

FAQ

This capacitor is designed for use in a wide range of AC motor applications, including air conditioners, heat pumps, pool pumps, air compressors, and washing machines. It is a standard replacement for Rolair part numbers FC009200075, U1107, and MK246.
If your motor is failing to start, humming loudly without turning, or running significantly slower than usual, the capacitor is often the culprit. A visual inspection may also reveal a bulging top, leaking oil, or a burnt smell, all of which indicate the internal dielectric has failed.
It is critical to match the microfarad (uF) rating exactly, as this determines the torque and performance of the motor. You can use a capacitor with a higher voltage rating than the original (e.g., 370VAC instead of 250VAC), but you should never use a lower voltage rating, as this can cause the capacitor to overheat and fail prematurely.
Installation is generally straightforward and can typically be completed in 15 to 30 minutes. You will need a screwdriver to access the capacitor housing and a pair of needle-nose pliers to disconnect and reconnect the spade terminals. Always ensure the power is disconnected and discharge the old capacitor safely using a resistor or insulated screwdriver before handling the terminals.
The ±5% tolerance indicates the acceptable range of the capacitor's actual capacitance compared to its rated 60uF. This means the unit will perform correctly as long as its measured value falls between 57uF and 63uF. This precision ensures the motor receives the correct phase shift for optimal efficiency and longevity.
Run capacitors are subject to heat stress and electrical wear during every cycle of the motor. Over time, the internal film can degrade, especially in environments with high ambient temperatures or frequent power fluctuations. Maintaining proper airflow around your motor and ensuring the capacitor is not mounted in an area with excessive heat can help extend its service life.
