If this is a Samsung range, then the C-d0 error indicates a stuck keypad key. Try pressing down on each key to jog the stuck one loose. If that doesn't work, try pressing down on each key from an off-center position on the keypad.
If this doesn't work to release the stuck key, you probably need to replace the entire keypad. Please add a comment with the range model number. I will see if I can find the correct part number for your range. If the range is under warranty, you can contact Samsung for a warranty repair.
-All burners or just one or two....?
-If all burners then gas pressure might be down due to On Off valve on the main pipe might turn 1/4 or more to closed position.
Make sure all On Off valve must turn to full open.
-But if only 1 or 2 burner do that then:
-Turn off gas valve to the stove before process.
-Remove all the cover and the inside orifice and soak it in warm water with soap.
-Use Only nylon brush or tooth brush to clean.
-Let air dry only. Do not wipe or dry it with towel or toilet paper.
