Today’s repair was the valve of the left small burner of my Force 10 gas stove. Two days ago there was a sudden flame surrounding the stove when I was boiling water. The left small burner was leaking gas. The valve moved with difficulty and did not shut off completely. Today, I took the valve apart (red circle), cleaned the parts with brake disc cleaner, and reassembled everything. Now, the stove works flawlessly again. No more gas leak. Yes, I have four recently serviced fire extinguishers and a fire blanket on board.
