DynaQ: The food temperature is not correct.

If the food temperature on the BBQ Guru control is about 15-20ºF hotter than another food thermometer, make sure you have the food probe fully inserted into the thickest part of the food. If too much of the steel shaft is exposed, it will cause the temperature to read hotter since the probe is picking up heat from inside of the cooker and not the actual temperature of the food.

If the food has a bone inside of it, be sure that the probe is not touching any part of
the bone.

If your food probe is incorrectly displaying a very high temperature usually in the high 400F range, your food probe may be bad or failing.

If the wire of the probe has small, hard, reddish bumps on the outside of the mesh, the food probe has been melted by direct flame or exposure to high temperatures. You will need to purchase a replacement probe here.
