2. Inspect all lead connections on motor for loose
or open connection
3. Replace switch
4. Replace capacitor

full power (power
output of motor de-
creases rapidly with
decrease in voltage
at motor terminals) 1. Power line overloaded with lights,
appliances and other motors
2. Undersize wires or circuits too long
3. General overloading of power
company’s facilities 1. Reduce the load on the power line
2. Increase wire sizes, or reduce length of wiring
3. Request a voltage check from the power com-
pany
Motor overheats Motor overloaded Reduce load on motor
Motor stalls (result-
ing in blown fuses or
tripped circuit break-
ers) 1. Short circuit in motor or loose
connections
2. Low voltage
3. Incorrect fuses or circuit breakers
in power line

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
