CAP025 Generic 25uF Run Capacitor, 25 Microfarad Universal Motor Run Capacitor for Appliance and Equipment Motors

This is a generic 25uF run capacitor, stocked as CAP025, for single phase motors that call for a 25 microfarad run capacitor. Being universal, it isn't tied to one appliance maker. What matters is that the value, voltage rating, size and terminal style suit the motor you're working on. Check those details on the label of your old capacitor, then confirm they line up with CAP025 before ordering.

Is the capacitor stopping your motor from starting?

Motors with a run capacitor rely on it to get turning and to keep running at full strength. Over time the internal film breaks down and the capacitance falls, so the motor loses torque. Common symptoms include a loud hum at switch on, a motor that needs a push before it spins, sluggish running, overheating, or a protective cut-out switching it off. If the case is bulged, split or leaking, don't refit it. A capacitance test will show whether the reading has fallen below 25uF.

Part details

• Capacitance 25uF (25 microfarad)
• Run capacitor type
• Generic universal replacement
• Stock code CAP025

Fitting a 25uF run capacitor

Switch off and isolate the supply, then safely discharge the old capacitor before you touch it. Note which wire goes to which terminal, and fit the replacement the same way. Secure it with the original bracket or strap. Use a capacitor with the same 25uF value and an equal or higher voltage rating. Anything hard-wired needs a licensed electrician.

Questions about this part

My old capacitor says 25uF but is a different shape. Will CAP025 still work?

Electrically it can, as long as the value matches and the voltage rating is equal or higher. Shape matters for mounting, so check it fits the space and the bracket, and that the terminals suit your wiring.
