SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Motor will not start 1. Low voltage 1. Check power line for proper voltage
2. Open circuit in motor or loose 2. Inspect all lead connections on motor for loose or
connections open connection
1. Short circuit in line cord or plug Motor will not start;
fuses blown or circuit
breakers are tripped 2. Short circuit in motor or loose
connections
3. Incorrect fuses or circuit breakers in
power line
1. Inspect line cord or plug for damaged insulation and
shorted wires
2. Inspect all lead connections on motor for loose or
shorted terminals or worn insulation on wires
3. Install correct fuses or circuit breakers
Motor fails to develop full 1. Power line overloaded with lights, 1. Reduce the load on the power line
power (power output of appliances and other motors
motor decreases rapidly 2. Undersize wires or circuits too long 2. Increase wire sizes, or reduce length of wiring
with decrease in voltage 3. General overloading of power 3. Request a voltage check from the power company
at motor terminals) company's facilities
Motor overheats Motor overloaded Reduce load on motor
1. Short circuit in motor or loose
connections
2. Low voltage
3. Incorrect fuses or circuit breakers in
power line
4. Motor overload
Motor stalls
(resulting in blown
fuses or tripped circuit
breakers)
1. Inspect connections in motor for loose or shorted
terminals or worn insulation on lead wires.
2. Correct the low line voltage conditions
3. Install correct fuses or circuit breakers
4. Reduce load on motor
Machine slows down Applying too much pressure to workpiece Ease up on pressure
