Pit Boss Lockhart Platinum temperature problems usually arise when the fire pot is not getting enough oxygen to achieve or maintain the desired temperature.

  • You will need to inspect the fan motor and all related components. If everything is still there after cleaning then it is not good work so the fan and motor need to be replaced.

It is extremely important that you make sure the P setting is set to the level you want. “P” stands for “Pause,” so as you adjust the setting, you are controlling the amount of pause feeding cycle time.

Know that when you increase the P setting, you are reducing the supply of pellets, which will result in more smoke and a lower temperature. Conversely, lowering the setting will give you less smoke and a higher temperature.

Pit Boss Pellet Not Burning

There are wood pellets in the hopper and fire pot of the Pit Boss Lockhart Platinum grill but the fire is not burning. There are three possible reasons for this auger not being primed, auger jammed or a broken igniter.


  • The Pellet hopper can be emptied for the first time or at any time. The auger must be primed to allow pellets to fill the auger tube. If not primed, the igniter will time out and stop before the pellets reach the fire pot.
  • Turn off the pellet grill by pressing and holding the power button. Remove the cooking components from the pit boss. Turn on your pellet grill and temperature control dial. Please inspect the auger feed system.
  • Check the auger is dropping pellets into the fire pot. If not working properly then the auger system needs to be replaced.
  • Remove all components from the pellet grill and turn the unit on, and its temperature control dial to smoke mode, and inspect the igniter.
  • To make sure the igniter is working properly, hold your hand over the pot of fire and if you feel the heat then the igniter is working. If the igniter isn’t working properly, it’s time to replace it.

Pit Boss Grill Produces White Smoke

Whilst the Pit Boss Blackheart Platinum emits a large amount of safe smoke, this means the food will not taste like smoke. Some of the main reasons for this are grease build-up, quality of wood pellets, blocked fire pot, and insufficient air intake for the fan.


  • Pellet grills are not cleaned properly, the main reason for grease build-up and clogging of the fire pot. Clean the fire pot and fire point, if there is clogging remove it gently.
  • Please check that you are using high-quality wood pellets. Also, make sure that the wood pellet you load into the hopper is free of moisture. It is better to replace yours with dry wood pellets.
  • Check out pellet grill fans. Make sure it is working properly and that the air intake is not blocked. If the pellet grill fan is not working properly after cleaning, replace it.

Pit Boss Flare-Ups

The question is if your Pit Boss Lockhart Platinum has flare Ups problems. This often happens for two reasons. One pellet grill’s temperature is too high and another grill’s cooking compartment has accumulated an excessive amount of grease.


  • First check the set temperature, if it is excessive then switch off the unit immediately and check the cooking compartment if there is grease then clean it. It is best to try to cook at a lower temperature.
  • Grease has the power to catch fire so before grilling session check the cooking compartment thoroughly and clean it if necessary. When cooking very greasy foods, the recommended cooking temperature is 250°F.

Flashing Dots

People often get annoyed when flashing dots appear on the Pit Boss Likkharat Platinum Series Pellet Grill LCD screen of the control panel. But what it really means is that the grill igniter is on.

That’s not a problem with the Pit Boss Pellet Grill, that’s a good sign. It simply indicates that your Pit Boss pellet grill is operating properly.

Pit Boss Shows ErH Error Codes

When the ErH error code appears on a pellet grill, it simply means that the grill is overheating or that there is a problem with the temperature control. When this happens there are three main reasons either the accumulated grease, excess fuel or there is a problem with the temperature probe.

Excess grease and fuel can cause overheating. Sometimes this is also seen due to a bad temperature probe.

Caution; If the temperature of your pellet grill overheats, turn the unit off immediately and do not operate until the grill has completely cooled.


  • Again, as a reminder, wait until the unit has cooled down before starting the test. If there are a lot of pellets in the fire pot, clean it and see if there is a build-up of grease, remove it immediately.
  • While monitoring you may find the cause of the overheating problem. Now check that the pellet grill is resolved, then turn the dial and open the pellet grill lid to clear the error message.
  • Before setting it to the desired temperature, the grill should be given some time to acclimatize and then set.
  • If your pellet grill is still showing the error code, check for the result of an improper connection between the temperature probe and the control system.
  • Because the temperature was extreme, if the meat probe didn’t have a problem before, it might now. Make sure the meat probe wire does not damage and is securely connected to the control panel.

ErL Error Codes Means

If you see the ERL error code on your pellet grill, it means that the temperature is too low, causing the pellet grill to shut down. This can result from bad pellets, lack of adequate airflow, a malfunctioning igniter, or lack of fuel in the fire pot.


  • So first you have to open the hopper and check for pellets. If there is no pellet in the hopper or moisture is found in the pellets, replace it immediately.
  • If the problem persists even after replacing the pellet, check whether the igniter is working properly. Check that there is enough fuel in the fire pot.
  • If everything is not fine then check the fan motor and clean it if necessary. Check whether the fan is running at the correct speed, otherwise replace the fan.
