You can take the burners out of the grill, and if you can get to the orifices, they will hopefully unscrew. You can use canned air and a pipe cleaner to clear any blockages. If you can't get to the jets after taking out the burners, you will have to do further disassembly of the grill. When you have the burners out you might also check for any blockage in the burner venturis.
