FAQ

If your motor hums but fails to reach full speed, or if it struggles to start and trips the breaker, the capacitor is likely failing. You may also notice the motor attempting to start and then shutting off immediately, or a visible bulge or leaking fluid on the top of the existing capacitor casing.
No, you must match the MFD (microfarad) rating specified by your motor's manufacturer. This capacitor is rated for 124-149 uF. Using a capacitor with a significantly different MFD rating can prevent the motor from starting correctly or cause permanent damage to the motor windings.
Always ensure the power to the equipment is completely disconnected. Before removing the old unit, discharge the capacitor by placing a resistor or an insulated-handle screwdriver across the terminals to prevent electrical shock. Additionally, inspect the wiring connections for signs of corrosion or heat damage, as these can also prevent a motor from starting.
The 220-250 VAC rating indicates the maximum voltage the capacitor is designed to handle. It is safe to use this capacitor in any application requiring 220V, 230V, or 250V AC. You should never use a capacitor with a voltage rating lower than what is required by your motor.
Replacing a start capacitor is generally a straightforward task that takes about 15 to 30 minutes. You will typically need a screwdriver to open the access panel and a pair of needle-nose pliers to disconnect and reconnect the spade terminals. Ensure you note the wire positions before removing the old unit to ensure the new one is wired identically.
