I have a generac 22kw model QT02224anan that will run for a few minutes then shut down , then the over speed led is lit. It only happens when it is under load or during a power outage. it goes through it's weekly exersize without any issues.

check your frequency of the ac, if this is high, then adjust the rpms.
If that is fine and it is shutting down, check overspeed adjustment on control board if it has it.

Sounds like a clogged fuel filter. Or the choke is on.

Leigh,
See my 5/22/12 comments on my "overspeed fault" problem resolution [Generac 43903 standby Generator overspeed indicator on starting] . If it only runs for a few seconds and then quits, you may have a similar condition to the one my unit had. A good technician should be able to diagnose the problem and determine if you have a similar failure to the one I had, or one of the other causes suggested by RSG000.

By the way, what is the make and model of your printer?

1. Resetting the Drum Page Counter
   • 1 Toggle switch in back of the printer. Shut off the printer.
     
   • 2 Front door opened Hold down the "Continue" button while opening the front door. Then turn on the printer.
     
   • 3 Error LED lit Keep the Continue button held down until only the "Error LED" is on then release the button. Close the door.
     
   • 4 Top 3 LEDs lit. The Continue button, Ready/Data, Toner Low, and Load Paper LEDs should all be lit up.
     
   • 5 Toner low LED lit. Press "Cancel" a few times to cycle through the LEDs until just the "Toner Low LED" is lit.
     
   • 6 Press and hold the "Continue" button until the LEDs cycle through and release only when the LED stops at Toner Low.
     
   • 7 Turn the printer off and back on.
     

I hope you find it very helpful. Best regards.

Hello, sounds like the limit switch is opening on the furnace.Usually when a furnace goes off on its high limit is becuase the airflow is being restricted making the furnace overheat. a limit switch is there to protect the furnaace from overheating, most cuases are either dirt or the blower motor not running up to speed, anything that cuts down on the airflow will cause the high limt switch to open.

John did you ever get this problem solved because I too am having a similar problem however for me it is also not shutting down automatically when the power is restored

fuel filter,,,or the speed governor may be binding up

I have a generator that did the same thing. It would start and then stop within a few seconds. The more expensive generators have an oil level safety switch to prevent the engine from burning up. There is usually a wire connecting to the switch on the outside of the engine near the oil fill hole. Remove this wire and try to start the generator. If it runs without a problem then it is the switch. You need to remove the switch and take it apart carefully and clean it. There is a small float inside the assembly. When the oil runs low the float allows the switch to short to ground which kills the spark to the spark plug. Hope that helps.
