SYMPTOM
MoOr will not Mart
Motor will not start;
fuses blown or circuit
breakersare tripped
Motor fails to develop full
power (power output of
motor decreases rapidly
with decrease in voltage
I at motor termmals)
Motor overheats
Motor stalls (resulting in
blown fuses or tripped
circuit breakere)
POSSIBLE CAUSE(S)
1. Low voltage
2 Open circuit in mutor or loose
connections
3. Defective switch
4. Defective capecltor

2. Short circuit in motor or loose
connections
3. Incorrect fuses or circuit brenkem in
power line

power line
4. Motor ovedoad
CORRECTIVE ACTION
1. Check power line for proper voltage
2. Inspect all lead connections on moor for loose or
open connection
3. Replace switch
4. Replace capacitor
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 wom insulation on wires
3. install correct fuses or circuit breakers
1. Reduce the load on the power line
2. Increase wire sizes, or reduce length of wiring
3. Request a _,,_tage check from the power company
Reduce load on motor
1. Inspect connections in motor for loose or shorted
terminals or worn insulation on ]eed wires
2. Correct the low line votiage conditions
3. Install correct fuses or circuit breakers
