Solution
Check: the phases; the cables; the plug; the socket.
Also check that the motor connections are in place.
Check that the voltages are present both on the input
and output. Otherwise replace.
Check that the phases in it are present both on the
input and output, that it is not jammed, that it closes
when powered and that it is not causing short circuits.
Change if any of these problems are found.
Make sure it is closed, i.e. check that the phases are
present in input and output, that it is not causing short
circuits and responds when the reset coil is closed. If it
has tripped to protect the motor, check the amperage
setting, reset, and check the motor. Change if
necessary.
Check that it has not burnt out, that it turns freely and
that there is no moisture in the connection terminal
board box. The winding can be rewound or replaced.
