What Does “Err” Error Code Mean On Pit Boss Pellet Grill?

The “ErR” code on the Pit boss pellet grill mainly refers to the malfunctioning of the grill temperature sensor or temperature probe. There are various factors that might be responsible for here. Either there is an improper connection of the probe with the grill or it is completely stopped working. 

The Remote Device (RTD) temperature probe is one of the major components in a pellet grill, located inside the main barrel, on the left side wall. The probe is figuring small, vertical piece of stainless steel whose core function is measuring the internal temperature of the unit.

When you start your pellet grill, the pellet starts igniting and the temperature on the grill increases. The temperature probe reads out the actual temperature from inside of the unit and adjusts it to your desired set temperature on the control unit. 

The grill will communicate with the probe to find out what temperature you need for cooking and add pellets to set the desired reading.  

In case the temperature stops reading temperature, the grill passes through a hard situation about which temperature it should run on and right then it displays the ErR or Er1 or at times ErL code. All these three codes refer to the same meaning.

Are Pit Boss Temperature Probes Interchangeable

Yes! The pit boss temperature probes are interchangeable only if it is well fitted to your pellet grill. For this instance, you need to insert the new branded temperature probe into your pellet grill and check whether it fits well without applying extra pressure to it.

The RTD temperature probe is a sensor on a pit boss which is basically up to 3.5mm in size. Along with the pit boss pellet grill, there are a few pellet grill brands that use the same sized and shaped temperature probe. They are:

  • Traeger
  • Camp Chef
  • Pit Boss
  • Memphis Grills

So in case, if you have a temperature sensor from any of the above brands, you can easily use it in your pit boss pellet grill and hopefully, it’ll work without any issue. 

Insert the probe into the bracket, secure it, and monitor the temperature whether the temperature effectively reaches the set temperature. For this instance, you use a handheld thermometer and compare it to your grill temperature.  

Can I Grill On My Pit Boss Without Using A Temperature Probe

Yes! Though temperature probes are a vital part of a pellet grill, you can grill even without using a temperature probe in case of an emergency. Here you need to use a handheld thermometer to monitor the grill temperature.

Almost all pellet grill including the Pit boss model uses up to a 3.5mm temperature jack inside of the main barrel that adjusts the internal temperature to the set one on the display. No doubt to say that it is one of the major components of the grill. 

But in case your temperature probe is damaged and there is no replacement part right this moment, no worry! You can easily run your grill without having a probe. Instead, you can use a third-party standard thermometer but it will never be a replacement for the RTD probe. 

  • Without installing the temperature probe, you need to lift the lid continually to monitor the temperature which is truly disgusting. 
  • Also, it may lead to the temperature to keep fluctuating. That will affect the food taste as well. 
  • So from the above perspective, we recommend installing a new temperature probe quickly if the previous one is damaged or not functioning properly.
