Questionable Probes?

Temperature Probes undergo a great deal of wear and tear, even in most normal cooking scenarios. The sensors inside of the probes can be damaged by shock (dropping) or moisture. Please use care when handling the probes. While there are definitely cases of damaged or defective probes, the first step in troubleshooting should always be to determine their true accuracy using one of the below tests.

Probe Accuracy

The accuracy of your FireBoard probes can be determined by performing an ice bath test or a boiling water test. It is critical that both tests are conducted properly - the ice bath test is somewhat easier to achieve consistent results.

Before doing any calibration tests, set your FireBoard’s Smart Temp Filter to off via the mobile app. You can turn if off in Devices > Advanced Settings > Smart Temp Filter. The Smart Temp Filter is designed to filter out bad readings from bad connections or sudden temperature jumps. In the case of ice bath or boiling water tests, the quick change to freezing or boiling temperatures would in some cases be filtered out.

Ice Bath Test

  1. Fill a container with ice, preferably crushed. It is critical to have plenty of ice! Add water until the container is nearly full.
  2. Insert the probe after allowing the water/ice mixture to settle for a couple minutes. While holding the end of the probe, gently stir the mixture with the probe - make sure the tip of the probe is in the middle of the ice/water container.
  3. Your probe should register within ±0.7°F of 32°F. If you’ve conducted the test correctly and feel like your probe’s reading is inaccurate, please contact us at

Boiling Water Test

  1. Fill a deep pot with water and place on a stove burner, set to HIGH. Let the water come to a strong, rolling boil.
  2. Insert the probe so that the tip is near the center of the mass of boiling water. Gently stir the water with the probe. Make sure the tip of the probe does not contact any surface of the container.
  3. Your probe should register within ±0.7°F of the boiling point for your area.

Temperature Differences

For some users, it can be startling to see the difference in your FireBoard temperature readings versus the temperature setting on your controller or the factory installed temperature gauge. Many people find that the accurate spot reading the FireBoard provides can vary greatly when compared to how you previously monitored the temperature. We test on many types of smokers - pellet fed, kamado style, offsets, kettles - and one thing they all have in common is that temperate is very dynamic inside of the cooking chamber. It’s not uncommon to find a ±50°F variance inside that mass of air, obviously some chambers are more efficient than others.
