- Disconnect power: Unplug the machine from the power source.
- Allow discharge: Wait 5-10 minutes for the capacitor to discharge.
- Access capacitor: Remove the cover to expose the capacitor.
- Safety precaution: Short the capacitor leads with an insulated screwdriver.
- Inspect capacitor: Look for signs of damage like bulging, bursting, or leaking oil.
- Test capacitor: Use a multimeter to check capacitor health. A good capacitor will show a reading rising from zero to infinity.
- Replace if necessary: If the capacitor is damaged or fails the test, replace it with one of the same microfarad value and equal or higher voltage rating.
- Disconnect power: Unplug the machine from the power source.
- Remove fan: Remove the fan cover and fan from the motor shaft.
- Access switch: Remove the dust cover and centrifugal switch.
- Inspect contact points: Check for closed points, welding, or excessive pitting.
- Clean or replace: Clean light pitting with sandpaper or replace the contact plate if necessary.
- Adjust switch: Position the centrifugal switch on the motor shaft until the contact points just touch, then go in another 1/16 inch and tighten the switch.
- Reassemble: Replace all components in the reverse order of removal.
- Power on: Plug in the machine and turn on the power switch.
- Monitor operation: Observe the motor's performance and ensure it starts and runs smoothly.
