35uF Hot Tub Capacitor - You will find that this particular hot tub capacitor fits most spa pumps.

Do not attempt to change a hot tub capacitor if the pump is still plugged in or the tub is still switched on. Capacitors generate very high voltage which can be dangerous.

Please note the images above is for example purposes only, most of the capacitors we sell now come with a screw connection at one end and either 2 wires (pigtails no connectors) or spade connections on the other.

The simplest way to explain the mechanics of a hot tub capacitor would be to compare it to a battery. Both store and release electricity. Capacitors are charged with electricity, then releases its stored energy at a rate of sixty times per second in a 60 cycle alternating current system. The sizing is critical to motor efficiency just as sizing of batteries is critical to a radio. A radio that requires a 9V battery will not work with a 1.5V size battery. Thus, as the battery becomes weaker the radio will not play properly. A motor that requires a 7.5 mfd hot tub capacitor will not work with a 4.0 mfd capacitor. Much the same way, a motor will not run properly with a weak capacitor. This is not to imply bigger is better, because a capacitor that is too large can cause energy consumption to rise. In both instances, be it too large or too small, the life of the motor will be shortened due to overheated motor windings. Motor manufacturers spend many hours testing motor and capacitor combinations to arrive at the most efficient combination.
