MOISTURE IN THERMOMETER
Moisture building in your thermometer can happen depending on the level of humidity or moisture in the environment. The easiest way to remove any moisture from the thermometer is to remove the thermometer from the grill, (simply unscrew the wing nut from the back of the thermometer) bring it into the house, and preheat your oven to 350 degrees. You'll need a casserole dish with a lid. Place the thermometer in the casserole dish, cover with the lid and bake for 30 minutes. Once you pull the casserole dish out of the oven, allow it cool for 30 minutes and it's ready to install back in the hood of your grill.
Char-Griller warranties the thermometer for the first year. Char-Griller Customer Service is happy to help with a warranty or replacement part order.
