not run
2. No electrical power, blown fuse, or tripped
3. Motor overheated / thermal overload open
4. Loose electrical connection
5. ON/OFF Switch bad
6. Pressure switch bad
7. Defective motor
Motor hums but 1. Low voltage
cannot run or runs
2. Unit is plugged into extension cord
slowly
3. Defective motor
4. Defective check valve or unloader valve
Fuses blow/circuit 1. Incorrect size fuse, circuit overloaded
breaker trips
repeatedly
2. Unit is plugged into extension cord
