CAP008 Generic 8uF Capacitor, 8 Microfarad Universal Appliance Motor Capacitor Part

CAP008 is a generic 8 microfarad (8uF) capacitor, sold as a universal replacement rather than as a part for one particular brand. Capacitors like this are fitted to single phase motors in all sorts of appliances, where they give the motor the push it needs to start and keep it turning smoothly. If the label on your old capacitor reads 8uF, CAP008 is the value to match.

Motor humming but not turning? Test the capacitor

A motor capacitor stores and releases charge to create the phase shift a single phase motor needs to start and run in the right direction. When it weakens or fails, the motor often hums without turning, starts slowly, runs hot, or only spins after a nudge by hand. A capacitor that is swollen, cracked or leaking is finished and should be replaced. You can confirm a weak one with a capacitance tester, comparing the reading against the 8uF printed on the label.

Part details

• Part number CAP008, generic universal capacitor
• Capacitance 8uF (8 microfarad)
• For single phase appliance motors that call for an 8uF capacitor
• Check the voltage rating and terminal style against your old part

Fitting a replacement capacitor safely

Unplug the appliance before you touch anything. A capacitor can hold a charge after the power is off, so discharge it safely before removing the wires. Photograph the connections, then move them across to the new capacitor in the same order. Make sure the new part's voltage rating is at least as high as the old one, and secure it firmly in its clip or bracket.

Questions about this part

Can I use a capacitor with a slightly different uF value?

It's best not to. The motor is designed around a specific capacitance, and the wrong value can make it run weakly or overheat. Replace like for like, so only use CAP008 where the old capacitor is marked 8uF.
