The gas burner under the stove gets too hot. What is the reason for this?

The gas burner is controlled based on the standard gas parameter. Further regulation might be necessary to achieve an efficient and correct flame. You can recognize an efficient and correct maximum flame by the fact that it has a length of about 15 cm. An efficient and correct minimum flame can be recognized by the fact that it has half the length of the maximum flame. Too little regulation of the minimum flame could cause an anomaly that heats the burner body. This phenomenon causes a recognizable noise (muffled gurgling). If this happens, it is necessary to immediately turn the burner node to the gas cap position (OFF) and make a proper regulation of the minimum flame of the burner.
