no hum on start-up

[David Mac]

hi

I have an A.O. smith motor on a Sta Rite Max E Glass II pump. The pool wasn't opened last summer.
So the pump was last operated 18 months ago. It was drained at that time.
2 years ago the pump was re- built . It was blowing fuses 2 secs after start-up.
Now when I flip the switch - nothing - no hum.

I even checked the fuses with a multi meter. They are fine.
I tapped the housing at start-up too.

I'll take the motor back to the shop .

Suggestions ?

TIA

Turn off power at breaker. verify power is off with meter at the pump deck.

Remove the motor wires at the terminal.

Set meter to ohms. check resistance of motor windings. A reading like 10 ohms is good a bad reading will be unreadable and display will flash its error message. ( OL on mine for over-limit.)

If windings are bad change motor out.

Now hums- motor wasn't getting power - wife flipped the fuse pack around - not clear mysefl - I'll edit this later.

one less headache.

Some fuse holders when flipped one way the fuses make connection with the circuit and flipped the other they are insulated from the circuit. They're no longer code but there a lot of them still around.
