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

Motor stalls (resulting in

blown fuses or tripped

circuit breakers)

1. Short circuit in motor or loose

connections

3. Incorrect fuses or circuit breakers in

power line

4. Motor overload

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
