I have a whirlpool bath that failed to start. The power is getting to the pump and it makes a buzzing noise like power there but it failed to start. I removed pump and checked switch, this is fine. I opened motor to see if pump had seized but I can move freely. I then went to control box and there is a capacitor. I believe this may be while the pump will not start. Can I check this with a volt meter ?

A picture would help, start capacitors are usually mounted on or very close to the motor, not in a control panel.
The easiest way to check it is to replace it, a dinky little capacitor like that won't be expensive. What is the rating printed on it?

Yep, 6uf capacitor, from what I`ve seen it doesn`t look like it popped but change it and see what happens. You could get 50% of costs back selling it on fleabay as a Saniflo capacitor if needed to.

What kind of switch is on these? Air switches have a habit of failing.
If the motor is humming but can be rotated by hand, it's either the capacitor or a winding on the motor has failed.
The cable is connected to both ends. I click the button and it turns the motor on to hum could it still be switch ?
A winding on a motor, is there anything I can do to check and if it is. Is it whole new pump or can it be fixed ?

Can you use a screwdriver to flick the impeller of the pump or the fan of the motor when the switch is on? If the motor bursts into life then it would be the capacitor. WARNING; flick and remove the screwdriver dam quick in one motion!
