CAP002 Generic 2uF Capacitor, 2 Microfarad Replacement Capacitor, Universal Appliance Part for Small Single Phase Motors

CAP002 is a generic 2uF (2 microfarad) capacitor for general appliance repair work. It isn't made for one brand, so it suits any appliance where the original capacitor is marked 2uF and the voltage rating and fixing also match. Small values like this are typically found on low powered single phase motors such as fan motors. Read the label on your old capacitor before ordering CAP002, and compare its size and terminal style too.

Signs a small motor capacitor has failed

In a single phase motor, the capacitor shifts the timing of the current in one winding, giving the motor the push it needs to start and keep turning in the right direction. When the capacitor weakens or fails, the motor may hum without turning, start only after a nudge, run slowly, get hot, or trip a safety device. A capacitor that is bulging, leaking or cracked should be replaced. A technician with a multimeter that has a capacitance setting can confirm whether the reading has drifted well below the 2uF printed on the case.

Part details

• Capacitance 2uF (2 microfarad)
• Generic universal part, not tied to one brand
• Stock code CAP002
• Check voltage rating and terminals against your old capacitor

Swapping the capacitor safely

Unplug the appliance or isolate it at the switchboard before opening it. Capacitors can hold a charge after the power is off, so discharge the old one safely before touching its terminals. Photograph the wiring, then connect the new capacitor the same way. Never fit a lower voltage rating than the original. If the appliance is hard-wired, have a licensed electrician do the job.

Questions about this part

Can I use a capacitor with a different microfarad value?

It's best not to. The motor was designed around a set value, and the wrong one can make it run hot, weak or noisy. Order the value printed on the old part, which for CAP002 is 2uF, with a voltage rating equal to or higher than the original.
