How to Detect Gas Leak from Your Stove

A gas leak from the stove? That’s not a recipe for a good meat pie. That’s a recipe for disaster!

Most homeowners, though, don’t know how to tell if a gas stove is leaking. They think everything is fine and dandy, and boom, fire or explosion goes out!

Let us walk you through the A to Z so that this type of problem never sets foot in your life. To be honest, there’s no room for a gas leak inside any kitchen!

How to Tell If Your Gas Stove is Leaking?

Here’s a fun metaphor: a stove gas leak is easy to spot. The signs are obvious, unlike money that mysteriously vanishes right after a payday. The following are some signs to look for:

1. Yellow Gas

The flame on your gas stove should fire its usual blue hue. If it turns yellow, it’s a sign that something is abnormal. A yellow flame means the gas isn’t burning effectively. 

Not only does it waste energy, but it also continuously produces carbon monoxide that can quietly poison yourself, your partner, your kids, and your pets. If you notice this, call a professional gas leak detection service.

2. Rotten Egg Odor

Do you smell a rotten egg? It might not be because your eggs are actually rotten. It might be a gas smell!

Naturally, a gas on its own is odorless, and that’s why gas leaks from the stove are hard to detect by smell only. Thankfully, utility companies add a chemical called mercaptan so that you can sense any fishy odor right away.

3. Hot to the Touch

If an oven door feels unusually hot, even after putting on your mitts, there might be a problem with the sealing or a gas leak waiting to explode. 

At a normal state, remember, the door should stay warm but not scorching.

Modern ovens come with natural insulation that is meant to trap heat inside. If the insulation doesn’t work anymore, fumes are escaping. This is a sign for you not only to escape, but also to run to your nearest licensed gas fitter.

What Should You Do If Your Gas Stove is Leaking?

Don’t panic. As we all know, it doesn’t solve anything – not even stopping a possum from entering your backyard. So instead, here are the right courses of action:

1. Don’t DIY

You might have gone down the YouTube rabbit hole of fixing gas leaks and come out feeling like you’ve earned a bachelor’s degree in the respective field in under an hour. 

But gas leaks aren’t the kind of problem you can DIY your way out of. Unlike fixing a squeaky door or patching a wall, dealing with gas requires licensed expertise, proper tools, and strict safety standards.

2. Call a Professional

What Usually Causes Gas Leak from Stove?

Here are some mistakes you’d want to avoid to prevent your gas from ever leaking:

  1. Cracked Pipes or Hoses. Materials can degrade, which leads to leaks. Always opt for strong and durable materials like black steel pipe or CSST (corrugated stainless steel tubing).
  2. Loose Connections. Over time, the connector where the flexible hose or pipe meets the inlet or shut-off valve can loosen, allowing gas to escape. Gas hoses typically have a service life of 5 years, so make sure to swap them out when the time is due.
  3. Improper Installation. A small mistake, such as using the wrong sealant or not securing fittings properly, can lead to harmful leaks. Follow the proper ways to install a gas cooktop for maximum safety.

How to Prevent Gas Leak from Your Stove?

Prevention is best when you try to avoid a problem before it occurs. Most homeowners, though, only check their gas leak when a professional is coming for an inspection. 

A cheat sheet that most people go by is the soapy water test. Apply a soapy water solution to gas lines and connections. If there’s a bubble, there might be a leak. 

It’s your sign to evacuate the area, ventilate it, and refrain from using any electrical appliances until an emergency service or a gas utility company arrives.

Most importantly, maintenance goes a long way. Heat, grease, and age cause wear and tear. Include routine checks in your gas stove maintenance schedule to re-tighten any loosening equipment.

Cleaning daily, weekly, monthly, or quarterly also helps get rid of spots, rust, discoloration, and unpleasant odor. When your kitchen stays visible and intact, it also prevents any hidden damage.

FAQ about Gas Leak from Stove

By now, you understand how to tell if your gas stove is leaking. But if you still have any other questions, check out the answers below.

1. What to do if stove gas was left on?

Wear your mask and immediately turn off the stove. Quickly ventilate the area afterwards by opening all windows and doors, and bring your loved ones outside. 

Ensure there are no signs of fire hazards, especially near the stove. Wait until the smoke is completely out before safely stepping in. 

Otherwise, call an emergency service. Prevent this issue from happening by installing a smoke detector, investing in a stove that automatically turns off after dormancy, or using a timer when cooking.

2. Is it okay to smell a little gas from the stove?

While a stove at times can emit some sort of odor (especially when you first light the burner), generally, it is not a good sign. 

Even a faint smell could indicate a leak that requires immediate attention. 

A strong, continuous, or persistent smell is an even bigger red flag, so turn off all your electronics and head outside. Most importantly, don’t try to fix the issue yourself – let the professionals handle it.

3. How long do I air out my house after a gas leak?

It depends on the severity of the leak and the quality of your home’s ventilation. But overall, after a leak, ventilate for at least 15 minutes to a few hours. Ideally, you should not come in until a gas company arrives and confirms that it is safe to do so.

4. Are there warning signs before a gas explosion?

Yes, and the warning signs are as clear as day. Signs to look for include rotten smell, yellow gas, dying house plants, and hissing sounds. 

If you feel symptoms like dizziness, nausea, and shortness of breath, especially after walking near or using a gas stove, there might be an underlying problem. Do not wait until the gas explodes – act now.

5. How long does it take for a stove to be on to cause carbon monoxide poisoning?

Exposure can become deadly in 1-2 hours, and in more extreme cases (like inside an area without ventilation), the timespan shortens to less than an hour. 

You can prevent this from happening in the first place by ensuring that your gas regulator functions normally. A broken system can cause incomplete combustion, which translates to more CO production. 

Conclusion

How can you tell if you have a gas leak from your stove? Well, you don’t need to wait for the universe to drop a sign, because a good look at your stove will reveal the clues. 

Never underestimate yellow plants, dying plants, or hissing sounds. They might be small, but if you leave them be, your gas stove might explode.
