I have a small airless compressor which now has ceased to run. The first symptom was that it tried to start but behaved as though it was jammed - i.e. hummed but did not turn. It now won't do anything. It appears to be driven but a capacitor-start induction motor. If I'm right, is the fault likely to be the starter? There is no smell of burnt-out wiring, so I don't think it is the motor itself. The motor and air pump turn perfectly freely by hand.
This state of affairs arose without warning when I went to use the compressor today. It was not a case of using it for an extended period and then it expiring.
Does anyone have any ideas, please?
