correct size. Check amp setting on
motor. If circuit size is correct, there is
probably a loose electrical lead.

connections on the planer including
motor connections, verifying the
tightness of each. Look for any signs of
electrical arcing which is a sure
indicator of loose connections or circuit
overload.

two options: Have a qualified electrician
test the motor for function or remove
the motor and take it to a qualified
electric motor repair shop and have it
tested.
Miswiring of the unit.
Check to confirm all electrical
connections are correct and properly
tight. Make any needed corrections.
On/off switch failure.
If the on/off switch is suspect, you have
two options: Have a qualified electrician
test the switch for function, or purchase
a new on/off switch and establish if that
was the problem on changeout.
