The gas stove was still ringing when it caught fire.

The crackling sound when the gas stove is on fire may be caused by the following reasons:

1. Spark device problem: The spark device may be out of order, resulting in a crackling sound during ignition. In this case, the spark plug needs to be replaced.

2. Gas pipeline problem: The gas pipeline may be blocked or leaked, resulting in unstable gas, and there is a crackling sound when igniting. In this case, it is necessary to inspect the gas pipeline and repair it in time.

3. Burner problem: The burner may be blocked or damaged, resulting in incomplete combustion of gas and crackling sound when striking a fire. In this case, it is necessary to clean or replace the burner.

4. Gas valve problem: The gas valve may be out of order, resulting in unstable gas and crackling when striking a fire. In this case, the air valve needs to be replaced.

In short, if the gas stove explodes when it is on fire, it should be inspected and maintained in time to ensure the safety of use. If you are not sure how to handle it, it is recommended to ask a professional to check and maintain it.
