What will you notice about a gas stove that is not working properly?

If a gas stove is not working properly, you may notice irregular or weak flames, which can appear yellow or orange instead of the standard blue color. There might be a strong smell of gas, indicating a leak or incomplete combustion. Additionally, the burners may not ignite or may take longer to light, and food may not cook evenly. Unusual noises, such as hissing or popping, can also indicate issues with the stove.
