Common problems

15
  • Unit will not start in AUTO with utility loss NOT ACTIVATED
    Fix: See activation section in installation manual.
  • Engine cranks but won't start
    Cause: 1. Out of fuel. 2. Fuel solenoid (FS) is defective 3. Open Wire #14A from Engine Control circuit board. 4. Spark plugs defective. 5. Door on tank not closed.
    Fix: 1. Replenish fuel. 2. Replace solenoid.* 3. Reconnect wire. 4. Clean, regap or replace plugs. 5. Close door on tank.
  • No transfer to standby after utility source failure
    Cause: Faulty transfer switch coil
    Fix: Contact an IASD.
  • Engine won’t crank.
    Cause: 1. 15 amp fuse blown. 2. Loose or corroded or defective battery cables. 3. Defective starter contactor. 4. Defective starter motor. 5. Dead or Defective Battery. 6. 5 amp fuse blown.
    Fix: 1. Replace fuse. 2. Tighten, clean or replace battery cables as necessary. 3. Replace contactor.* 4. Replace starter motor.* 5. Remove, change or replace battery. 6. Replace fuse.*
  • Engine cranks but will not start
    Cause: Out of LP fuel
    Fix: Replenish LP fuel. Turn on fuel shutoff valve.
  • Unit consumes large amounts of oil
    Cause: Engine over filled with oil
    Fix: Adjust oil to correct level.
  • Engine starts hard, runs rough.
    Cause: 1. Flame arrestor (air cleaner) plugged or damaged. 2. Plugged fuel line. 3. Defective spark plugs. 4. Fuel pressure incorrect.
    Fix: 1. Clean or replace as needed. 2. Unclog fuel line. 3. Clean, regap or replace plugs. 4. Confirm fuel pressure to regulator is as recommended in SPECIFICATIONS.
  • Unit will not start in AUTO with utility loss. NOT ACTIVATED
    Cause: Unit not activated
    Fix: Refer to activation section in owners manual.
  • Warning active LOW BATTERY
    Fix: Clear alarm. From MAIN menu on the control panel, navigate to BATTERY MENU. Contact an IASD if battery is GOOD. Replace battery if CHECK BATTERY is displayed.
  • Engine oil level is low.
    Cause: 1. Engine is overheated. 2. Defective Low Oil Pressure Switch 3. Defective Coolant Temperature Switch 4. Defective Control Module circuit board 5. Coolant Level is Low. 6. Defective Low Coolant Level Switch
    Fix: 1. Check cooling system for leaks. 2. Replace switch.* 3. Replace switch.* 4. Replace board.* 5. Repair leak - Add coolant. 6. Replace Switch.*
  • Engine starts hard and runs rough
    Cause: Air cleaner plugged or damaged
    Fix: Inspect/replace air cleaner.
  • Unit will not start in AUTO with utility loss — LED RED LOW OIL PRESSURE
    Cause: Check LEDs / screen for alarms
    Fix: Check oil level and add oil as needed. If oil level is correct, contact an IASD
  • No AC output from generator.
    Cause: Defective AUTO/OFF/MANUAL switch Open/disconnected wire #15A between AUTO/OFF/MANUAL switch and Control Module circuit board.
    Fix: 1. Replace switch.* 2. Reconnect/close wire.
  • Engine starts then shuts down.
    Cause: AUTO/OFF/MANUAL Switch at OFF, engine continues to run
    Fix: *Contact the nearest Authorized Dealer for assistance.
  • Engine does not crank
    Cause: Fuse blown
    Fix: Replace 7.5 amp fuse in generator control panel. Correct short circuit condition if fuse blows again.
