Pit Boss Pro Series 850 Problems (4 Problems with Fiexs)

The Pit Boss Pro Series 850 is a reliable grill that conveniently prepares delicious meals. However, this powerful grill can experience problems if not properly maintained.

Common problems with the Pro Series 850 include clogged burners, leaking smoke and heat, difficulty maintaining temperatures, and build-up of residue on the interior walls.

In this article, I discuss the common Pit Boss Pro Series 850 problems and how to fix them easily.

Pit Boss Pro Series 850 Problems

1. P Setting not Working

The “P Setting” on the Pit Boss Pro Series 850 is designed to give you precise control over the internal temperature of your grill or smoker.

 It allows you to set a specific temperature and maintain it for cooking, smoking, or grilling.

However, some users have experienced difficulty getting the P setting to work correctly.

There are several possible causes: insufficient oxygen supply, clogged burners, faulty thermometers, and clogged air intakes.

To fix this problem, start by cleaning out any blockages in the burners or air intake.

Ensure there is enough airflow so that oxygen can reach the burners, and check that each burner produces a good flame. 

If needed, replace any faulty thermometers with new ones and adjust any settings as indicated in the manual for your particular model.

2. Heat Distribution Issues

Heat distribution issues can arise with the Pit Boss Pro Series 850 due to various factors.

Poor positioning and inadequate air flow around the smoker can lead to uneven heat distribution, resulting in some areas being hotter than others.

Temperature fluctuations can also cause poor heat distribution.

The fan in the controller may be running inefficiently or may not be running at all, resulting in inadequate airflow and trapping heat.

Checking the fan to ensure it is working correctly and repositioning the smoker can help improve heat distribution. 

Also, keeping an eye on the temperature gauge can help alert you when changes are needed to address any issues with heat distribution.

3. Ignition System Troubleshooting

Ignition System Troubleshooting can be complicated but is necessary to ensure optimal performance and safety of your Pit Boss Pro Series 850 Grill. 

The ignition system provides the spark that ignites the gas grill’s burners.

If there is an issue with your ignition system, the grill may not light or stay lit during normal operation.

If your grill will not light, the first thing to do is check that you have a proper fuel supply. Make sure you have sufficient propane in the tank and that the valve on the tank is open.

 If there is no fuel, you need to solve this problem before continuing with ignition system troubleshooting.

If there is a proper fuel supply, the next step is to check the ignition system. Inspect all connections, wires, and system components, such as the spark generator and igniter electrodes.

 If these components appear in good condition, check for a spark at the electrodes.

4. Temperature Fluctuation

Temperature fluctuations are a common problem with the Pit Boss Pro Series 850. If a smoker experiences severe temperature swings can affect both the quality and taste of their food. 

Temperature fluctuations occur when the fire or fuel source is not burning evenly, or when air circulation is inadequate.

This can be caused by poor heat distribution, blocked air intakes, or inadequate fuel sources.

To fix this issue, start by inspecting the fire for any potential blockages or obstructions preventing air from entering the firebox.

 Make sure all air intakes are open and clear of debris, then check your fuel source to ensure it is burning evenly and not producing too much smoke.

You may need to adjust the fuel source or modify the air intake to get better airflow and heat distribution.

5. Contact Customer Service

 If you are having trouble with your grill or require assistance with troubleshooting, parts replacement, or warranty information, contact customer service immediately.
