CAP06.3 Generic 6.3uF Capacitor with 8mm Mounting Stud, Universal Appliance Motor Capacitor Part

CAP06.3 is a generic 6.3uF capacitor with an 8mm stud for mounting. Single phase appliance motors in fans, pumps and some washing machines rely on a capacitor like this to start and run. It is a universal part, so the key is matching the capacitance, voltage rating and terminal style to the one you are replacing.

Motor humming but not turning? Check the capacitor

A motor capacitor gives a single phase motor the extra push it needs to start and helps it run smoothly. When the capacitor weakens or fails, the motor may hum without turning, start only after a nudge, run slowly, overheat or trip its thermal cut-out. In a fan the blades may barely move, and in a pump or washer motor the load may never get going. A bulging, cracked or leaking case is a clear sign of failure, and a capacitance tester will show a reading well under the marked 6.3uF.

Part details

• Capacitance 6.3uF
• 8mm mounting stud
• Generic universal replacement
• Suits single phase appliance motors that call for 6.3uF

Replacing a motor capacitor safely

Before anything else, kill the power at the power point or switchboard. Capacitors can hold a charge after power is removed, so discharge the old one before touching the terminals. Photograph the wiring, then swap the wires across one at a time. Check the voltage rating on the new capacitor is equal to or higher than the original. Hard-wired appliances should be handled by a licensed electrician.

Questions about this part

Can I use a different uF value?

No. Use the same capacitance as the original, which for this part is 6.3uF. The wrong value can make a motor run hot, weak or noisy. Match the voltage rating and mounting style too.
