What does a capacitor do on a hot tub pump?

Motor capacitors are used with hot tub pumps/motors and come in two common types: run capacitors and start capacitors. Run capacitors are designed for continuous duty while the motor is powered. Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly.

How do you test a pump capacitor on a hot tub?

Testing the Capacitor with a Multimeter

1. Remove the cover at the back of the motor or on top of the motor to expose the capacitor.
2. The capacitor will store an electrical charge.
3. Remove the leads to the pool pump capacitor.
4. Set the multimeter on ohms to 1K.
5. Slip a heavy piece of paper between the points on the switch.

Why does my hot tub pump hum when I turn it on?

When I turn on the power to my hot tub at the breaker, I can hear the relays closing and the pump hums for a short while, but it doesn’t turn. I recently drained and filled my hot tub. After refilling, I ran the pump for a few minutes to circulate some chemicals, so it was working at the time.

Why does my hot tub make a low noise?

A: If your spa pump never actually turns on, it only makes a low noise, until the circuit breaker trips, check these things. First, would be the capacitor on the motor. This cylindrical “battery” provides extra starting power, and these can go bad after many years.

Why does my hot tub pump keep humming?

The pump of your hot tub is humming uncontrollably and you have no idea why. There might be some water in a place that there shouldn’t be, or there might not be any noticeable problems. Either way, if the humming gets progressively more loud, you know you are not going to have a nice soak.

What to do if your hot tub circulation pump is not working?

Disconnect the plumbing and turn it on very briefly to see if any funny noises are made. Depending on the location of the problem, a replacement of the bearings, motor, entire circulation pump will be required. Pro-Tip: Your spa circulation pump should run with as little noise as possible.

How old is the motor on my hot tub?

That said, the hot tub and pump are over 9 or 10 years old, so it must be time for a new motor. I checked the voltage coming from the control panel to the pump (both high and low speed) and got 0.
