CAP012 Generic 12.5uF Capacitor, Universal Appliance Capacitor, 12.5 Microfarad

CAP012 is a generic 12.5uF capacitor, a universal part for appliance repairs where the old capacitor carries the same microfarad value. It isn't tied to one brand, so the key checks are on the capacitor you're replacing: its uF value, voltage rating, terminals and mounting. This listing confirms the 12.5uF value but not the voltage rating, so ask us before ordering if the voltage matters for your repair.

Motor humming but not starting? Check the capacitor

Many single phase appliance motors, pumps and fans rely on a capacitor to help them start and run in the right direction. When a capacitor weakens or fails, the motor may hum without turning, start only if the shaft is given a push, run slowly or hot, or trip the power. A swollen, cracked or leaking case is a clear giveaway, but capacitors can also fail with no visible sign. A capacitance tester will show whether the old one has drifted below its rated value.

Part details

• Generic universal capacitor, part CAP012
• Capacitance 12.5uF
• Aftermarket part, not tied to one appliance brand
• Voltage rating not stated, check before ordering

Safe capacitor replacement

Unplug the appliance or switch it off at the wall before touching anything. A capacitor can hold a charge after power is removed, so discharge it safely before handling the terminals. Photograph the wiring, note which lead goes to which terminal, and fit the new capacitor securely in its bracket. Hard-wired equipment should be handled by a licensed electrician.

Questions about this part

Can I use a 12uF capacitor instead of 12.5uF?

Match the value printed on your old capacitor. This part is listed at 12.5uF. If your old one reads a different value, ask us through the parts enquiry form before ordering rather than guessing, as the wrong value can affect how the motor runs.
