Who is GENERAC?

Generac is the top seller of home personal backup generators. Generac has created and launched the category of home backup generators.

Today it is reported that the Generac generator is favored by seven out of 10 homeowners that decide to buy home backup power.

An installed Generac household backup generator will protect your house by automatically securing your home in case that there is a power failure.

Generac generators operate on propane, or natural gas (also known as LP) fuel. They are installed on the outside of your property similar to central air conditioning units could.

Generac’s home backup generator Generac backup generator for your home supplies energy directly to your electric system in your home. it can be set in order to protect the entire house or only the essential things.

The Generac generators for backup power can be utilized in various markets, including residential, commercial as well as industrial. It is the Generac generator’s power source ranges between 800 watts up to 9 megawatts.

Like any other electrical equipment, it may be a source of an error or errors. Error code 2800 is one illustration of an error that you might encounter when using an Generac generator.



I first became aware of the issue that the generator not running anymore via Generac’s Mobile Link application. When I opened the app, I was able to see the error message below:

Error Code 2800 as shown in the Mobile Link app.

When you visit the Status History page of the application, you’ll be able to see more warnings about errors, and the generator has been stopped because of an alarm.



What Does Error Code 2800 Look like on Generac Generators

As I walked outside to check my generator, I noticed I could see that the light was red “Alarm” lamp was lit:

A Generac generator’s red “Alarm” light triggered by Error Code 2800.

When you start your generator and then go to the control panel, it will go through two errors. The first one indicates that the generator is stopped due to an alarm. Error Code 2800.

Error Code 2800 as shown on a Generac generator (error message 1 of 2).

Second error is that the generator is shut down because of an issue with the Auxiliary Shutdown Switch:

Error Code 2800 as shown on a Generac generator (error message 2 of 2).

When you read these errors (particularly because that the Mobile Link app indicates that your generator requires repaired) You might conclude there is something serious wrong that occurred to the generator. Rest assured, your generator is fine! This is how you can repair Error Code 2800.



What can be done to correct the error code 2800?

When you inspect the generator, there will be an alarm red light When you turn on the generator’s control panel, the interface is able to cycle between two errors.

The two messages are iron and can have different meanings, such as one shows the generator has stopped functioning due to the secondary shutdown switch, while the second one is indicating that the operation of the generator was shut down due to an alarm triggered by errors 2800.

This means that you must get your generator serviced or turn off the secondary shutdown switch to ensure to use the instructions in the following section. However, when doing this, it is important to be attentive, follow this step with care. Now let’s start.

Step 1: Find the Auxiliary Shutdown Switch at the rear of the generator.

Switching on the Auxiliary Shutdown Switch results in error code 2800. (which could have happened by accident). The Auxiliary Shutdown Switch is located on the exterior of each Generac Generator model. Its Auxiliary Shutdown Switch for our model is located on the left-hand side of the back of the generator:

In the event that you check that the Auxiliary Shutdown Switch is OPEN (O symbol) then the generator will not begin and an “Auxiliary Shutdown” warning will sound instead. If you press the O symbol for the Auxiliary Shutdown Switch is depressed the generator will cease to function and it will generate the error code E2800. To assist you in seeing this Auxiliary Shutdown Switch in the OPEN (O symbol) place more clearly I’ve zoomed it in on the following image:

Error Code 2800 is often resulted from it being caused by the Auxiliary Shutdown Switch on the side of the generator. It was evident that our generator’s switch was accidentally press.

Step 2: Adjust the Auxiliary Shutdown switch to its CLOSED (– symbol) Position.

Adjust the Auxiliary Shutdown switch in the CLOSED (I symbol) setting by pressing on the CLOSED (| symbol) end of the switch in order to fix the error code 2800.

Step 3: If it is applicable Check your Auxiliary Shutdown Switch to the right of the generator.

Another Auxiliary Shutdown Switch is found inside Generac generators of at least 16 kW, near the interface for control panels. In order to make it clear I’ve highlighted this additional switch on the photo below:

The internally located Auxiliary Shutdown Switch is hidden within the generator’s lid (and it’s likely that you’ve secured the lid as well! ) This makes it extremely unlikely that the switch was accidentally turned. It is, however, never hurts to make sure you double-check the switch.

Step 4: Remove the Genec error code 2800 out of the Control Panel

The panel’s interface to the control panel will prompt you to eliminate the error or alarm after verifying that both the secondary shutdown switches have been pressed until they reach the closed ( symbol) position. It’s just easy as the text implies! Just press the gray “ENTER” button, after you have pressed the red “OFF” button in your control panel.

Then, turn on the generator’s totally auto-pilot system by pressing “green “AUTO” button (allows the generator to auto begin to exercise and start it according to an timer for exercise).

Step 5: Run the generator using Manual mode.

Even though you’ve concluded that you’ve solved the problem technically, I would like running the generator manual for a short time.

Be sure to verify that it starts to crank to run, particularly when it’s not in operation or keeping pace with the training schedule for too lengthy.

The only thing you need to do in order to begin your generator is to press the blue manual button.

The blue light in the control panel will show that the operation is manual. If the generator is able to start without issue, let it run for about a couple of minutes.

Step 6. Restore the generator back to Auto operation.

When you Press “green” on your “AUTO” button once you’ve been set, you’ll be able begin to restart the generator’s full-automatic operation.
