Is Your Pit Boss Display Not Working? (5 Reasons + Solutions to Fix It)

Is the display of your Pit Boss unit not working?

Not to worry.

This post will guide you on how to troubleshoot and fix your Pit Boss display issue.

Like other electrical appliances, the Pit Boss grills can also develop electrical and mechanical issues.

One of the most common issues with the smoker is the display not working.

Here, we will look at some of the common causes of Pit Boss display not working and solutions

Note: We recommend contacting the Pit Boss support team if you’re having trouble with your screen

Disconnected From Power Supply Outlet

Funny as it may seem, many people often forget to plug in their Pit Boss wood pellet grill to a power connection outlet.

As a barbecue beginner or even a seasoned pit master, It’s easy to get carried away with the thoughts of smoking your favorite meal that you forget to plug in your grill.

You’d be surprised that something as simple as this could be the cause of your blank LCD screen.


So, whenever you notice that the LCD screen of your Pit Boss isn’t displaying.

The first thing you should do is check whether it is properly connected to a working outlet.

This would save you a lot of trouble.

Bad Circuit Board Fuse

If the LCD screen of your Pit Boss smoker still remains blank after you’ve confirmed that it is properly connected to an outlet, the circuit board amp fuse has probably tripped and needs replacement. For more information on Pit Boss blowing fuses see here.


This may initially seem like a frustrating issue but it is easy to fix.

All you have to do is replace the blown fuse.

If you still have your user’s manual, look over it for instructions on how to replace the circuit board fuse.

Tripped Ground Fault Circuit Interrupter (GFCI / GFI)

One of the common issues that could cause a blank screen on Pit Boss pellet smokers is a tripped GFI.

The GFI outlet is designed to prevent electrical shock when connecting a device but can trip if broken or have many heavy accessories connected to it.


Here’s a quick fix – check the wire connections and ensure they’re fully secured.

In addition, make sure the wires are completely dry. 

Another thing you can do is disconnect all appliances connected to it, leaving only the Pit Boss smoker connected.

If it doesn’t work still, then you may have to do further troubleshooting.

Disconnect your Pit Boss, then connect another appliance like a refrigerator to the GFI to see if it works.

If other appliances work, then your Pit Boss is faulty and you may have to replace the grill igniter.

On the other hand, if other appliances do not work, then you need to call a technician or contact Pit Boss customer service (if under warranty) to have the GFI fixed.

Faulty Extension Cord

This is another factor that could make your Pit Boss display not work.

As you may already know, the extension cable is what supplies power to your Pit Boss.

If the power cord is damaged, it will supply insufficient voltage to your Pit Boss, leading to a blank screen.


The solution to this problem is very simple. All you have to do is replace the extension cord. Once you do that, the display should come on.

Insufficient GFI AMP

If your Pit Boss doesn’t work on a specific GFI, it could mean the GFI is bad. The easiest way of detecting is by checking the GFI outlet’s amperage.

If the amperage is less than 15, your Pit Boss won’t get enough power for its display.


Try using a different GFI for your smoker.

However, if only one GFI outlet is suitable for your Pit Boss system, then you should try replacing it.

Here’s how to go about it:

  • First things first, make sure you switch off the main power supply in your home
  • Remove the faceplate of the GFI
  • Unscrew the outlet, then pull it out
  • Disconnect all the wirings completely
  • Put a new outlet, then reconnect the wirings just like it was
  • Screw the GFI and its faceplate back to their position
  • Finally, switch on the main power supply.

After completing the above steps, check the amperage of the GFI outlet. If it is above 15 AMP, the display of your Pit Boss unit should come up immediately you plug it in.

Other Display Issues

Pit Boss models tend to have 2 types of error messages displayed on the screen – ErH and ErP.


This type of error message means there’s a problem with the temperature control of the grill.

It could mean either the temperature probe wire is not connected properly, or the grill is overheating.

Excess fuel could be the cause of the overheating.

To get this issue resolved, put off the grill and have the pellets cleared from the firebox.

Another reason for the ErH message could be as a result of a grease fire in the cooking chamber.

To resolve this issue, switch off the grill and allow the flames to go out.

Alternatively, you can use kosher salt or baking soda to douse the flames if it doesn’t go out on its own.

After the overheating has been resolved, clear the error message by turning the dial off, then open the grill lid.

Wait for some minutes, and then turn the control dial to your desired temperature.

The ErH message could also display as a result of an improper connection between the temperature control system and the g wire.

For this, check the wire for damages and make sure it is properly connected to the control panel.


The ErP symbol is an indication that the temperature settings dial was probably left on when the grill got connected to the AC power (it is a basic safety feature that prevents the system from starting up accidentally).

Getting rid of the ErP is very easy. All you have to do is turn the cooking temperature dial off.

Then wait for a few minutes before turning the setting button to your desired temperature.
