If you look at the picture to the right you will see the inside of the TEC burner. The holes running down the side are where the screws that hold the burner together used to be. These screws are sheering off and popping right out of the burner. Char-Broil has changed their story from "this is normal" to "we can send you a replacement burner" (you pay shipping and handling). Now it appears that Lowe's has been authorized to take back defective grills for full refunds.
WARNING: If you own the Char-Broil/TEC grill you need to remove the cooking grate and glass plate from the burner (gas turned off) and inspect the screws inside this burner. If any of these screws are broken or missing you need to contact Char-Broil immediately. Call 1-888-430-7870 for assistance. While there is currently no recall or safety alert regarding this grill there is clearly something wrong. Char-Broil is supplying replacement screws and newly designed burners. I fully encourage you to be safe and make sure you Char-Broil/TEC grill is safe to operate.
