Then check if there any damage to the temperature probe wires.

Make sure the temperature Probe spade connectors are firmly connected and correctly, to the Control Board.

If the temperature probe is damaged, then you have to replace it with a new one.

Clean the temperature probe

The temperature probe should be clean otherwise dirty probe won’t work precisely.

You need to check whether the probe is properly clean or carbon accumulated on it.

Just a few microns of residue will not change the way an RTD will sense temperature.

But if there is a lot of carbon accumulation on the RTD probe it may show the wrong results.

So, it is important to clean and maintain the RTD probe for the right operation of the grill.

Also, check it is not bent and touches the side of the grill.

If you find the probe dirty, you need to clean it the right way.

How to Test If The RTD Temperature Sensor Is Bad/ Faulty?

Before going to know, how to test the RTD probe, we will discuss in brief what an RTD temperature sensor is? And why they get faulty?

Here RTD means for Resistance Temperature Detector.

The RTD probe comes in different designs but it works on the same principle that uses fine wire.

RTD sensors and quite accurate but they are very fragile in nature.

So, they will operate for many years in other stoves like boiler or pellet stove but may not work that much longer in a pellet grill.

Pellet grills are generally shifted around and you need to be careful while doing so.

Because the RTD probe is warm and the fine wire can easily break while moving it.

Now you need to clean it thoroughly and feed quality pellets in the grill hopper.

You have to check the RTD sensor temperature with another temperature sensor.

Thanks to the built-in analogue temperature dial on Pit Boss. This makes our job easier!

Pit boss pellet grill has analogue temperature dial built into the grill lid.

For testing the RTD probe, you have to check the internal temperature on the analogue dial. Compare both the temperatures that show up on the analogue dial and RTD sensor.

But there are variations on the analogue dial and RTD sensor reading as the analogue dial is far higher than the cooking grate.

For a more accurate temperature comparison, you can use a heat gun. This heat gun will show you an accurate temperature.

It measures surface temperature ranging from -58℉ to 1382℉/ -50℃ to 750℃ with using infrared technology.

You can directly aim the heat gun at the RTD temperature sensor. you can expect very few degrees variations between the RTD sensor and heat gun.

If there are high variations you need to replace the RTD sensor with a new one.

With the heat gun directly aimed at the RTD temperature sensor, you should expect to see the results between the heat gun and the digital readout within a few degrees of each other.

If that’s not the case, the RTD sensor is faulty.

How to Replace Pit Boss RTD Probe?

If you got the ErR error on your pit boss, in some cases your RTD probe is faulty and you need to replace it with a new one.

Let’s get to know how to remove the old RTD sensor and replace it with a new one.

For this, you need to remove the grill hopper. Clip the zip ties.

Now you need to remove the RTD wires from the controller.

For this, you just have to lose two flathead screws that hold the wires in its place.

You have to give a slight turn to the wires and wires will come out easily.

Then you have to remove the screws holding the RTD plate located at the back of the grill.

Remove the screws on the plate located over the RTD probe and the plate will come off.

Then you have to remove the screws and nuts that hold the RTD probe in its place.

Once you remove these screws and nuts, then pull out the RTD probe and wires of RTD.

Installing the new probe on Pit Boss is simply a reversal of this process.
