Why Your Pit Boss Temp Is Blinking (Learn Why and How to Fix It)

Have you noticed the grill temperature numbers flashing on your Pit Boss’s LCD screen? Although this may sound frustrating, we have solutions to help you quickly resolve it.

This guide will explain how the Pit Boss temperature monitoring systems work, why it is flashing on your Pit Boss smoker, and how to fix them. 

5 Reasons Why Your Pit Boss Temperature Is Flashing

The Pit Boss indicator lights blink for one of the following reasons: the grill is not hot enough, the auger is obstructed, the temperature probe is dirty, or there aren’t enough pellets in the hopper.

Below, you’ll find more information on each reason, followed by a section on how to fix it.

Note if you see the ER1 code or ERH code, we have further information about them.

Pit Boss Struggling to Hold Temp

The flashing temperature on the LCD screen means the temperature inside the Pit Boss is too low. This occurs when Pit Boss grills cannot reach the correct temperature or experience a drop in temperature.

When you set the grill to ‘Cook’ mode, the temperature will flash when it goes below 150°F or 65°C. In the ‘Smoke’ mode, the lights will flash if the temperature is below 110°F or 43°C.

In ‘Cook’ mode, the temperature can be set between 225°F to 500°F

In ‘Smoke’ mode, the temperature can be set between 200°F to 250°F

Temperature Probe Is Dirty 

A dirty probe is a common cause of temperature swings in Pit Boss grills. The RTD probe is designed to maintain consistent temperatures inside the Pit Boss smoker.

When dirty, it won’t detect the correct temperature inside the unit, which can cause the flashing temperature issue or even shut the unit down.

When you open the Pit Boss grill, you will see the probe on the side that the hopper is on. It’s a small temperature probe built into the smoker. If it has black soot or grease on it, it is most likely the issue.

The Are’nt Enough Pellets in The Hopper

Pit Boss grills also tend to experience temperature issues when there aren’t enough pellets in the hoppers. Ensure you have enough pellets in your hopper so that auger can feed the burn pot.

Feeding System Isn’t Working 

If the auger jams, the pellets won’t pass through the tube and into the firepit, which means it won’t work correctly.

One of the main reasons for an auger jam is if you have wet or moist pellets; another reason can be a build-up of ash or grease. The auger can also break a gear or lose it shear pin that connects the auger to the motor.

How to Fix Temp Blinking on Pit Boss

Now that you understand why the pellet grill temperature blinks, we’ll provide a of solutions to each of the problems to fix them.

Clean Your Temp Probe 

If you find the temperature probe dirty, clean it after every cook. This will help prevent the buildup of soot.

To clean the grill temperature probe, use a sponge with soap and water/vinegar, an old toothbrush, or a paper towel. If you do use a sponge and vinegar, place something between the probe and the unit so that it doesn’t get scratched. Avoid using any strong cleaners such as oven cleaners to clean inside your grill, as they can transfer to the food.

Avoid soaking the probe in water, as this can severely damage the wires, resulting in false temperature readings or the probe too short out. Also, check the wire connections to ensure the probe is firmly attached to the control panel. 

Examine the Firepot

Using a shop vac, remove any ash buildup from the fire pot. Check the auger and unclog the any obstructions you can find.

If you find the auger and firepot are clean your Pit Boss might just need a deep clean

First, you’ll need to remove the grease tray and cooking grates. Make sure there is enough airflow to the burn pot and no obstructions. You can also clean the grease tray to eliminate the gunk and residue that has built up over time. 

The Pit Boss has a safety feature that automatically removes the pellets from your grill. This feature lets you perform a deep cleaning of the hopper and auger.

Check That There Is Sufficient Pellet Supply 

You’ll want to open your hopper grill lid and check for sufficient fuel to keep the grill running. If you can see the auger you will need to add more pellets. You also want the pellets to be level. Tunneling is a big issue, this is when the pellets make a tunnel shape void, that stops the grill from getting enough fuel to run

We recommend filling your Pit Boss Smoker up to the top with a dry batch of pellets to ensure you won’t run out when cooking. Always check to see if there are enough pellets before beginning cooking. 


Use High-Quality Pellets 

Pit Boss advises using high-quality pellets to ensure the grill works at it optimal performance. These pellets will burn hotter for extended periods, provide a better hardwood flavor and make sure the grill get hot enough to work correctly.

Avoid using pellets with unnatural additives in your Pit Boss smoker. Instead, use 100% all-natural hardwood fuel for your Pit Boss grill. 

Look for Any Obstructions 

Clean the grill using a shop vac to collect debris, ash buildup, and loose particles in the firepot. Then, use a clean cloth or paper towel to remove the grime inside. 

Check the auger, and remove any obstructions, if it the auger is working correctly it may just need a deep clean.

Why Do I See a Flashing Dot On My Control Board Screen? 

If you notice a flashing dot on the control board display, the grill’s igniter is on. In this scenario, there’s nothing you’ll need to worry about.

You won’t need to touch the control temperature settings either. After five minutes in the startup mode, the ignitor automatically turns off. 

Dealing with mechanical issues with your Pit Boss pellet grill can be annoying. However, luckily, the pellet grill temperature blinking issue is relatively straightforward.
