magnetic starter not working

Check that the ON button is not stuck. Sounds like the STOP is opening the circuit to the starter coil but the ON is still engaged.

Contacts must be stuck on the “ON” button.
If the case looks askew, it may be binding on the button.

Oops, I see that was already suggested while I was away from the computer..

try it with the cover off if it works properly take care reassembling andtryagain

Magnetic starters can get corrosion on the contacts. When
this happens the starter won’t stay in a position. That’s
one issue that can come up. The contacts can be
reconditioned with fine wet/dry sandpaper. Taking
apart the starter will probably be required.

Under power the magnets on one side of the switch
may be pulling harder (contacts in better condition)
one way that the other. I had this problem with
the starter on an old 3 phase machine. In my
case the motor would not stay on because the
springs in the starter were pulling stronger than
the “on” position magnets.

Also explore lubricating the moving starter parts with
graphite to make sure it is not binding.

Hold back on that graphite suggestion.

Graphite is carbon.
Carbon is a conductor.
Might be the equivalent of spraying powdered iron into the electrical works.

I’d rather lube it up with motor oil than graphite.
Actually they make lubricants specifically for these type devices.
But be careful, they usually contain silicone which is a no no in the finishing department.

LPS3 should work shouldn’t it??

Don’t see why not.
