  2. Generac Generator Error Code 2400 Fuse Problem
I'm being flooded with questions about the 2800 shutdown fault code for Air Cooled Generac generators... This code is VERY simple to fix. The new Generac WiFi products that are shipping come standard with the Aux Shutdown kits installed. The 15kW are larger units have 2 switches, while 14kW and lower use just 1 switch. The switches are located one on the very back of the unit just below the roof line near the electrical connections and the other is located INSIDE the generator on the black firewall panel in the upper right corner. These MUST BOTH be on for the unit to run. If either or both are turned off, the unit will show that alarm and not run. If either switch is turned off during the unit actually running, it will shut down. These are for emergency personnel in case there is a problem where the unit must be safely and quickly shutdown. There is a section in the owner's manual that will explain all about them as well.

After seeing tons of search data for the forums and answering tons of questions both here and on the phone, this chart seems like a helpful idea! The following are some common e-Codes from the Generac Evolution controller that you may see if there is a problem. There is a short description next to each one explaining a possible problem and a solution. Controller Fault ALARM The controller has. Welcome to Your Activation / Registration Site. Your automatic standby generator requires activation in order to operate automatically. This is a simple one-time process that only takes a few minutes and will also serve as the product registration.
