You don’t adjust a misaligned burner cap

An unaligned burner cap can prevent ignition. “If the igniter on your gas stove clicks and clicks without the burner ever lighting, check to make sure your burner cap is in place and properly aligned. If you aren’t sure, listen to see if the igniter is louder than usual,” says Berry. Much like a clog, this can cause corrosion and shorten the life of the appliance.
You ignore the signs of a gas leak

Gas leaks don’t simply shorten the life of your stove top. If the appliance explodes, it will need to be replaced – and, of course, an explosion can also be deadly. The smell of gas is usually a good indication that there’s an issue. “While it’s normal to smell a small amount of gas when you turn on the range, if the smell appears before you turn the appliance on and lingers across your home, this might indicate a leak and a hazardous condition that needs immediate attention,” Berry explains. “Promptly open the windows and call your local gas supplier from outside of your home.” Your oven isn’t the only appliance that can explode.
You try to fix the problem yourself

In most cases, appliance repair is best left up to professionals. “There are instances where an individual may try to repair their appliance, and they’ve got it all taken apart, but unfortunately then realize they can’t figure out what’s wrong with it,” says Berry. “And furthermore, they realize they can’t figure out how to put it back together.” This can also cause additional damage and end up making repairs more expensive.
