How To Fix Pit Boss ErL Code or Er1 [Reasons + Solutions]

The Pit Boss ErL code isn’t as common as some of the other Pit Boss error codes. It indicates that the smoker flame is too low and the desired temperature can’t be achieved for that matter.

The common causes behind the ErL error code are- control board failure, chimney cap set too low, a bad temperature probe, a jammed auger, a broken thermostat, faulty igniter, and improper wiring. 

How To Fix Pit Boss ErL Code/Er1 [Reasons + Solutions]

Now, we’ll take a deeper look at the causes behind ErL code and the simple solution you can perform to fix them.

1. Control Board Failure

This is by far the most common reason why users have to deal with the ErL error code. The number of factory failures on the Pit Boss control board is high. A faulty control board will lock your smoker system and it won’t function properly.


Repairing the control board by replacing a component on it isn’t worth it when it comes to the control board. The fix will likely not last for long. Instead, replace the entire control board with a new one.

Contact Pit Boss customer service and let them know the trouble you’re having. You can expect them to ship a control board to you. Watch this video to see how you can replace the control board on your Pit Boss.

2. Chimney Cap Set Too Low

The chimney on a Pit Boss allows the smoke to leave the smoker. The cap is adjustable and the user can control the height.

Not all Pit Boss smoker models have a chimney cap. But if your model has one and it is set too low, this stops the excess smoke to leave out through the exhaust.

The smoke in your smoker smothers the flame causing a low flame that stops the smoker from reaching the desired temperature. The ErL code will show up when this happens.


It is best to leave a two-finger gap on the chimney cap and the base of the chimney stack. Turning the chimney cap to the left loosens it and widens the gap. 

You can place your fingers between the gap to see if it is wide enough or try wedging a piece of cardboard into the gap. In case the cardboard fits into the gap, the gap is good.

3. Bad or Dirty Temperature Probe

A temperature probe is a type of sensor that is used to detect and measure the internal temperature of your smoker. In case you have a faulty or dirty temperature probe, the ErL error code may appear on your display. 


You need to check your temperature probe for any signs of excess dirt or damage. Here’s how you can clean your temperature probe in case it turns out to be dirty.

  • Clean the temperature probe with a mixture of water and vinegar. Rinse the temperature probe as thoroughly as possible with a solution of one part water to one part vinegar.
  • Vacuum the grill and clean the fire pot to finish off.

If your temperature probe turns out to be damaged, you need to replace it. People with some electrical knowledge should easily be able to DIY replace the temperature probe.

4. Jammed Auger

When your pellet stove’s auger gets jammed, fewer pellets are fed to the flame which results in a weaker flame. This can lead to ErL. Your auger can get jammed due to any of the following reasons.

  • Using pellets of lower quality.
  • The dust has accumulated inside the auger.
  • Using pellets of the incorrect size.
  • The auger motor has worn out.
  • The Pellet chute is clogged.
  • Using the stove on a regular basis.


To unclog a jammed auger, follow the instructions given below.

  • If your stove has a manual auger feed feature, use it to help move any stuck pellets or dust through the auger.
  • Remove any pellets or pellet dust from the hopper’s bottom that may be clogging the pellet stove auger.
  • In case the pellet chute is reachable, clean it out.
  • Clean out the auger as much as possible.
  • Check that the auger motor is working properly, or have a professional technician look at it as part of the stove’s annual or seasonal service.

5. Cold Weather

Usually, the cold weather shouldn’t affect the ability of your smoker to function properly.

But if the outside temperature is cold, pellet consumption to reach the desired smoker temperature will increase. In this situation, if your hopper doesn’t carry sufficient pellets, the flame will get weak.


This one is the easiest to solve. Just ensure that your hopper is full of high-quality pellets that burn clean and long. Another thing you should try out which will save you pellets and therefore, money, is an insulating blanket. 

Insulating blankets will keep your smoker shielded from the cold weather and keep it warm. So, you’ll need fewer pellets to maintain the desired temperature.

6. Ignition Failure

Ignition failure can also result in the ErL error code. Any of the following reasons can be behind an ignition failure.

  • The build-up of ash in the firepot.
  • Moist pellets
  • Faulty igniter


Here are some things you can try to fix the issue of ignition failure. 

  • After each cook, clean up the ashes.
  • Take out charred black pellets that you can find in your firepot.
  • Take out any damp pellets that you can spot in the firepot.
  • To avoid problems with igniting, use high-quality pellets. For a hotter and cleaner burn, I use Pit Boss BBQ Wood Pellets.
  • In case you have a damaged igniter, you can try cleaning it. If that doesn’t work, replace the igniter. I recommend the QuliMetal Grill Hot Rod Igniter if you need to change the igniter.

7. Improper Wiring

An incorrectly wired smoker can be the reason why the Pit Boss smoker ErL code is showing up on your display.

Generally, the wiring issue is most likely to be found in the connections made to the control board and those made to the temperature probe.


Check the wiring diagram that you can find in your Pit Boss smoker’s user manual. Inspect the wiring of your smoker with reference to the wiring diagram.

Correct anything if needed. Ensure that the connections are secured properly. Also, replace any damaged wires.


How do you reset Pit Boss?

You can reset your Pit Boss by turning it off and unplugging it. Let it rest for 30 minutes and start it back up. 

What are the P settings on a Pit Boss smoker?

A lot of smokers have the P-setting including Pit Boss. P stands for pause. It is essentially the feeding rate of pellets to the auger. The amount of pause there will be before the next pellet is fed.

Why is my pit boss pellet grill overheating?

You may be having trouble with your smoker overheating due to an excess of pellets in your hopper, lack of airflow, hot weather, damaged components, faulty control board, bad temperature probe, improper P-setting, etc.

Which pellets produce the most smoke?

Hardwood pellets are the greatest for smoking since they have a considerably longer burn period than the more typical fruit wood pellets.

Can you leave pellets in the hopper?

Leaving pellets in the hopper isn’t a good idea as your pellets will be exposed to the elements which can cause them to rot. Most Pit Boss Grills come with a hopper clean-out mechanism that makes cleaning and changing pellet flavors a breeze.
