E15
A-iPower standby generator shows E15 and refuses to transfer load even though it is running.
Transfer Switch Communication Fault
E16
Controller displays E16 and logs a fuel-related alarm; generator may shut down or refuse to start.
Fuel Level Sensor Fault
E17
Generator controller shows E17 and logs an intake air fault; engine may run poorly or shut down.
Intake Air Temperature / Pressure Sensor Fault
E18
Controller displays E18 and the generator may shut down with a fuel system warning.
Fuel Solenoid / Shutoff Valve Fault
E19
Generator controller shows E19 and logs an exhaust or emissions-related fault.
Exhaust Temperature / Sensor Fault
E20
Controller displays E20 and the generator will not start; often accompanied by a service reminder.
Maintenance Interval Exceeded / Service Required
Symptom
Control panel display is blank or intermittent, but the generator may still run or crank.
Control Panel Power / Display Failure
Symptom
Corrosion, rust, or water accumulation is visible inside the generator enclosure.
Moisture Ingress / Corrosion Damage
Symptom
Fuel smell around the A-iPower standby generator, especially during or after operation.
Fuel Leak / Fuel Odor
Symptom
Generator cranks but will not start; no error code is displayed on the A-iPower controller.
No-Start Condition Without Fault Code
Symptom
Generator does not start automatically during a utility power outage, but can be started manually.
Failure to Auto-Start
Symptom
Generator emits visible white, blue, or black smoke from the exhaust during operation.
Abnormal Exhaust Smoke
Symptom
Generator enclosure is hot to the touch and internal components show signs of heat stress, but no overheat code is present.
Inadequate Ventilation / Enclosure Overheating
Symptom
Generator fails to shut down after utility power is restored; continues running with or without load.
Failure to Auto-Stop
Symptom
Generator frequently starts and stops (short cycling) even when there is no power outage.
Nuisance Starting / Short Cycling
Symptom
Generator is excessively noisy during operation compared to normal, with rattling or knocking sounds.
Abnormal Mechanical Noise
Symptom
Generator runs but produces no AC power; controller shows normal run status with no error code.
No AC Output Without Fault Code
Symptom
Generator runs but some circuits in the building experience flickering lights or unstable power.
Intermittent Power / Flicker
Symptom
Generator runs but voltage is low (lights dim, motors struggle) even though no error code is displayed.
Low Voltage Output Without Code
Symptom
Generator starts and runs, but the automatic transfer switch does not transfer the building load to generator power.
Failure to Transfer Load
Symptom
Generator starts but immediately stalls within a few seconds; no code is logged.
Start-Then-Stall Condition
Symptom
Generator vibrates excessively, causing the enclosure to shake and nearby structures to rattle.
Excessive Vibration
Symptom
Oil leaking under the generator or visible oil on the engine surfaces.
Engine Oil Leak
