The downside to customer support help, is it can take a while to get the assistance you need. I’ve personally contacted customer support when I first bought my grill and it took over a week to hear back from them.

If your grill is still under warranty, you should still contact them. They will probably send you a new control board because the one in your grill is bad.

If you don’t want to wait on customer support to send you a new control board, you can purchase a replacement on Amazon. It’s not expensive, and you’ll have a backup, when you get the replacement from Pit Boss.

Here’s a kit I found on Amazon that comes with a temperature control panel board, thermostat control board, temperature probe and more.

Preventing the Pit Boss Er1 Code

Your next question is what can I do to prevent the Er1 Pit Boss error code? Unfortunately, there’s not a lot you can do to prevent it.

Some grill owners may never experience this code. While other grill owners saw the Er1 code when their grill was a few months old.

Think of it like buying a car. Two people may have the same car, one works fine, while the other one has all kinds of mechanical issues. When products are mass-produced, quality control can suffer.

Final Word

The Er1 code is not a common Pit Boss error. If the code shows up on your display, it means there’s an issue with the temperature probe or its wiring.

To troubleshoot the issue, you’ll have to dismantle the smoker, so you can get to the control board. Ensure the probe wire is connected properly to the control board, and check for any damage.

You likely have a bad control board and should contact Pit Boss, so they can send you a replacement.

If your grill isn’t under warranty, you can find a replacement on Amazon.

Unfortunately, there isn’t a way to prevent this error. That said, if you follow the care and maintenance instructions provided by Pit Boss, you will be able to get the best outcomes from your pellet grill!
