Had my first 2800 Aux Shutdown Fault code today. With your help, it was easy to find that simple rocker switch turned off! I must have bumped it while weed whacking the generac! Thanks for your help. Saves a service call for something silly I did! :bigsmile:

Hi, I’m having the same issue. Both switches are on and now it’s saying “press off, then enter to clear alarm”. When I do that, nothing happens. Any advice? Thanks

You may have a loose connection or a bad switch. A beep type continuity tester will help since the switches just make a complete path back to the control panel. Keep in mind this unit is probably under warranty!

I had a 22kw generator that came with one of the switches assembled “Backwards” where “O” was closed and “|” was open. Try alternating switch positions while clearing the code.

Hi. I have a Generac 20kw generator. For several days, I am presenting
error 2800. According to the manual, this error is cleaned by disconnecting
the battery and the control panel, but when I reconnect them, I have the
same error again.

A message appears on the panel screen. STOPPED - ALARM
Assistant Court.

I would appreciate your help..

Hi! You need to make sure BOTH aux shutdown switches are set to on. There is one inside near the engine at the front, and one on the outside rear of the unit.

The alarm is cleared by putting the unit to Off, then back to Auto once they are switched back on.
