We have a chocolate fountain which has packed in as the motor that drives the Archimedes screw thing in the middle won't spin. If I turn it manually it 'catches' then spins on to the next part of the wiring loom (or at least that is what it feels like) then stops again. I can't dissemble the motor so I tried attaching the spline to a drill and spinning it (thinking that perhaps the brushes had corroded and needed a little persuasion) but unfortunately that didn't work.
Does anyone have any ideas on how I might resurrect it?
Thank you.
Does it have brushes? if not it may have a start/run capacitor that could have failed.
easy/cheap to replace if you can find it.
If it's an AC motor then it will probably be the capacitor as above, if it's DC then a duff winding/muck on the commutator. If you can strip the motor you can use a multimeter/continuity tester to satisfy your inquisitiveness. Otherwise fix with a new one.
