Moisture in Thermometer
Moisture building in your thermometer is not common but if you live in an area with extended rain or high humidity, moisture can build upon the face of your thermometer. It's very easy to address. To remove any moisture from the thermometer, you will remove the thermometer from the grill, 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. If moisture is allowed to build inside thermometer and not addressed or replaced and then heated, pressure can build under the glass which could cause the glass to break.
Char-Griller warranties the thermometer for the first year. Char-Griller Customer Service is happy to help with a warranty or replacement part order.
