The unmistakable aroma of wood-fired barbecue is a siren song to any grilling enthusiast. But what happens when your Pit Boss pellet grill refuses to cooperate and stubbornly refuses to heat up? The frustration can be immense, especially when hungry guests are anticipating a delicious meal. Don’t despair! This comprehensive guide will walk you through the most common reasons why your Pit Boss isn’t heating up and provide you with step-by-step troubleshooting solutions to get your grill back in action.
Understanding How Your Pit Boss Works
Before diving into troubleshooting, it’s crucial to understand the basic workings of your Pit Boss pellet grill. These grills operate using an automated system to feed wood pellets into a firepot, where they are ignited to create heat and smoke. A fan circulates air to maintain consistent temperatures, and a control panel allows you to set and monitor the desired cooking temperature. Any malfunction in this system can prevent your grill from heating up properly.
Common Culprits: Identifying the Heating Problem
Many factors can contribute to your Pit Boss’s heating woes. Let’s explore some of the most common culprits, ranging from simple fixes to more complex issues.
Pellet Problems: The Fuel Source
The quality and condition of your wood pellets play a significant role in your grill’s performance. If your Pit Boss isn’t heating up, the first thing to check is your pellet supply.
Low-Quality or Damp Pellets
Low-quality pellets often contain fillers and binders that don’t burn efficiently, resulting in inadequate heat. Similarly, damp or moldy pellets struggle to ignite and maintain a consistent flame. Always use high-quality, food-grade wood pellets from a reputable brand. Store your pellets in a dry, airtight container to prevent moisture absorption. Visually inspect the pellets for any signs of mold or excessive dust. If you suspect your pellets are the problem, empty the hopper and replace them with a fresh batch.
Empty Pellet Hopper
This might seem obvious, but it’s a common oversight. Ensure your pellet hopper has an adequate supply of pellets. The auger needs a sufficient amount of pellets to draw from to consistently feed the firepot. A nearly empty hopper can lead to inconsistent feeding and temperature fluctuations, ultimately preventing the grill from reaching the desired temperature.
Igniter Issues: Sparking the Flame
The igniter, also known as the hot rod, is responsible for igniting the wood pellets in the firepot. A faulty igniter is a frequent cause of heating problems.
Faulty Igniter
If the igniter isn’t functioning correctly, it won’t generate enough heat to ignite the pellets. To test the igniter, carefully observe the firepot during the startup sequence. You should see the igniter glowing red hot within a few minutes. If it remains dark or only flickers dimly, it’s likely faulty and needs replacement. Replacement igniters are readily available online or at your local hardware store.
Igniter Placement
The igniter needs to be positioned correctly within the firepot to effectively ignite the pellets. If it’s misaligned or covered in ash, it may not function properly. Consult your owner’s manual for the correct igniter placement. Use a shop vacuum to thoroughly clean the firepot and ensure the igniter is free from debris.
Auger Anomalies: Feeding the Fire
The auger is a screw-like mechanism that transports pellets from the hopper to the firepot. Any issues with the auger can disrupt the fuel supply and prevent the grill from heating up.
Auger Jam
Auger jams occur when foreign objects, such as small twigs or oversized pellets, become lodged in the auger tube, blocking the flow of pellets. To clear an auger jam, first, disconnect the power to your grill. Then, empty the pellet hopper and access the auger tube. You may need to use a tool, such as a screwdriver or pliers, to carefully dislodge the obstruction. Avoid using excessive force, as this could damage the auger.
Auger Motor Malfunction
The auger motor is responsible for powering the auger. If the motor is faulty, the auger won’t turn, and pellets won’t be fed into the firepot. Listen closely to the auger motor during the startup sequence. If you don’t hear it running or if it sounds strained, the motor may be failing. You can test the motor using a multimeter to check for continuity. If the motor is indeed faulty, it will need to be replaced.
Airflow Obstructions: Fueling the Fire Properly
Proper airflow is essential for combustion. Insufficient airflow can stifle the flame and prevent the grill from reaching the desired temperature.
Dirty Firepot
A firepot filled with excessive ash can restrict airflow and hinder the combustion process. Regularly clean the firepot after each use to remove ash and debris. Use a shop vacuum to thoroughly clean the firepot and ensure optimal airflow.
Grease Buildup
Grease buildup in the grill can also obstruct airflow. Excess grease can drip into the firepot and smother the flame. Clean the grease trap and grease drain regularly to prevent grease buildup. Consider using a drip pan to collect grease and prevent it from dripping into the firepot.
Blocked Exhaust Vents
The exhaust vents allow smoke and hot air to escape the grill. Blocked vents can restrict airflow and cause the grill to overheat or fail to reach the desired temperature. Inspect the exhaust vents regularly and clear any obstructions, such as grease or debris.
Temperature Sensor Troubles: Reading the Heat
The temperature sensor, also known as the RTD (Resistance Temperature Detector) probe, monitors the grill’s internal temperature and relays this information to the control panel. A faulty temperature sensor can lead to inaccurate temperature readings and prevent the grill from heating up properly.
Faulty Temperature Sensor
If the temperature sensor is malfunctioning, the control panel may display inaccurate temperature readings, causing the grill to overcompensate or underperform. You can test the temperature sensor using a multimeter to check its resistance. Consult your owner’s manual for the correct resistance values at different temperatures. If the sensor is faulty, it will need to be replaced.
Sensor Placement
The temperature sensor needs to be positioned correctly within the grill to accurately measure the internal temperature. If it’s misaligned or obstructed, it may provide inaccurate readings. Ensure the sensor is properly positioned and free from obstructions.
Controller Conundrums: The Brain of the Operation
The control panel is the brain of your Pit Boss grill, regulating the auger, igniter, and fan. A malfunctioning control panel can disrupt the entire grilling process.
Faulty Control Panel
A faulty control panel can cause a variety of problems, including incorrect temperature settings, failure to ignite the pellets, or inconsistent auger operation. Try resetting the control panel by unplugging the grill for a few minutes and then plugging it back in. If the problem persists, the control panel may need to be replaced.
Incorrect Settings
Double-check your temperature settings to ensure you’ve selected the desired cooking temperature. Accidentally setting the temperature too low can prevent the grill from heating up properly. Consult your owner’s manual for instructions on how to set the temperature.
External Factors: Elements Beyond the Grill
Sometimes, the problem isn’t with the grill itself but with external factors that affect its performance.
Cold Weather
In extremely cold weather, it can take longer for the grill to reach the desired temperature. The ambient temperature can significantly impact the grill’s heating performance. Consider using a grill blanket to insulate the grill and help it retain heat in cold weather.
Wind
Strong winds can also affect the grill’s heating performance by dissipating heat and disrupting the airflow. Position the grill in a sheltered location away from strong winds.

Why is my Pit Boss not reaching the set temperature?
Another significant cause is a dirty fire pot. Ash buildup restricts airflow, hindering the combustion process. Regularly cleaning the fire pot after each use is crucial. Also, check the RTD temperature probe. A faulty probe can misreport the internal temperature to the control board, causing it to underfeed pellets and prevent the grill from reaching the set point. Inspect the probe for damage and ensure it’s properly positioned within the cooking chamber.
What does the “LEr” error code mean on my Pit Boss grill, and how does it affect heating?
The underlying causes of an “LEr” error can range from a lack of fuel (pellets) in the hopper to a malfunctioning igniter. A damaged or improperly positioned igniter won’t effectively light the pellets, triggering the error. Another possibility is a faulty auger motor, which is responsible for feeding the pellets into the fire pot. If the auger isn’t working correctly, the grill will starve for fuel, leading to the “LEr” code and preventing proper heating.
How do I troubleshoot the igniter if my Pit Boss isn’t lighting?
Next, check the igniter’s electrical connection. Ensure the wires are securely attached to the igniter and the control board. A loose or corroded connection can interrupt the power supply, preventing the igniter from heating up. If you have a multimeter, you can test the igniter for continuity. If the igniter shows no continuity, it’s likely faulty and needs replacement.
What role does the RTD temperature probe play in heating issues, and how can I test it?
To test the RTD probe, you can use a multimeter. First, disconnect the probe from the control board. Then, set the multimeter to measure resistance (ohms). Place the multimeter probes on the RTD probe’s terminals. The resistance reading should correspond to the ambient temperature of the probe. A significantly different reading or an open circuit indicates a faulty probe that needs to be replaced. Some Pit Boss models also have a diagnostic menu that displays the RTD probe’s temperature reading, allowing you to compare it to a known temperature.
How can I identify and fix airflow problems that prevent my Pit Boss from heating up properly?
Another factor influencing airflow is the cleanliness of the grill itself. Excessive grease buildup inside the grill can restrict airflow and affect temperature consistency. Periodically clean the interior of the grill, including the drip pan and grease trough, to ensure unrestricted airflow. Furthermore, ensure the grill is placed in an area with sufficient ventilation, avoiding enclosed spaces that could limit airflow.
What impact do the quality and storage of pellets have on my Pit Boss’s heating performance?
Proper pellet storage is equally important. Pellets are hygroscopic, meaning they readily absorb moisture from the air. Storing pellets in a damp environment, such as a garage or shed without proper sealing, will cause them to swell, crumble, and burn poorly. Always store pellets in a dry, airtight container in a cool, dry place. Consider using a desiccant pack within the container to further prevent moisture absorption.
What regular maintenance steps can I take to prevent heating issues in my Pit Boss grill?
Furthermore, thoroughly clean the entire grill interior at least twice a year, or more frequently depending on usage. Remove the grates, drip pan, and grease trough and clean them with soap and water. This prevents grease buildup, which can restrict airflow and create a fire hazard. Regularly inspect the igniter and auger system for any signs of damage or wear and tear, addressing any issues promptly to prevent more significant problems.
