Why Does My Gas Oven Smell Like Gas When Turned On

Why Does My Oven Smell Like Gas

Ovens are a staple appliance in the kitchen. Almost every household in the United States has one. It’s where dinners and desserts are made–classic dishes that bring the family together, ones that the whole family loves. From meat loafs and lasagnas to cookies and pies, they are all made and bakes using a good oven.

There are two main types of ovens, depending on how you keep it operational. One type is the electric oven, where you use electricity to start up the machine that keeps it going. With a push of a button, the oven heats up by the jumpstart of the electric charge.

The other type of oven is the gas oven, which has a more complicated operational process. Gas ovens use pilot ignition to work. Pilot ignition works with a pilot light or a small gas flame where it is responsible to light the burner of the oven. As the thermostat is turned on and increased, the burning flame gets bigger and envelops the thermocouple bulb of the oven’s safety valve. The safety valves open, allowing for the gas to flow to the pilot light to ignite the burner.

Both types of ovens are available in the market for everyone to purchase. Some residential places like condominiums and apartments do not allow or discourage the use of gas ovens due to safety reasons. However, gas ovens are still are a popular choice for homes because of its affordability. Gas oven users must just know safety precautions and how to recognize if a gas oven is malfunctioning.

In this article, we shed light on how gas ovens work and the implications and cautions of using it safely and successfully.

Even with the possible risks and dangers of using a gas oven, there are several advantages of using one over an oven that is powered electrically. Some of the known strong benefits of cooking with a gas oven are:

  • Moist cooking – gas ovens maintain a moist cooking environment
  • Cooking control – temperature is more controlled, and heating up and cooling down of the oven are almost instantaneously
  • Energy efficient – less energy is consumed
  • Lower Costs – no power charges involved
  • Dependable – even without power, gas ovens can operate
  • Durable – proven to have a longer life span than electric ovens. You just need to annually check for leakage

Parts of a gas oven

A more popular choice of gas oven is one that has a stove top. The oven sits at the bottom of the gas stove where it usually has four burners. A gas oven have these basic parts in order to function:

  • Burner – gas ovens usually have one burner below the oven floor to heat up the space, and an internal electric fan to help distribute the heat
  • Pilot light – burning flame that ignites the gas to heat up the oven
  • Pilot Gas Supply Line – connections that supplies gas to the pilot light to make the flame bigger or smaller
  • Thermostat – used to set the function of the oven for baking or broiling temperature
  • Valves/Control panel – control knobs that switches on and off, and adjust the pilot light and burner to control temperature

These parts work together to successfully bring heat to the gas oven for you to use.

Oven Smells

Should your gas oven emit the smell of gas?

The answer is no. Not at all.

However, when you first start your oven, there might be an unusual odor in the air that should go away after within a few minutes. This unusual odor is not the same as a smell of gas. Rather, it is the smell of unburned gas, which some people describe like the smell of rotten eggs.

Unless your oven has been serving you for at least 15 years, your oven should never emit the smell of gas when you turn it on or especially while you use it.

When you smell gas when the oven is turned on, there might be a possibility of leakage, which can lead to very dangerous mishaps. As soon as you smell the odor of gas, you should shut down the oven and promptly call your gas supplier. You should not touch any electrical switches as it might give you an electrical shock and could possibly lead to fire.

Caution 101

Your gas stove must always be kept clean and maintained. Most providers often warranty and free annual check-ups. Checking for possible leakage is usually done by service provider professionals. But if you are confident enough to check by yourself, here is a step-by-step guide on how to find and fix a leak. Remember to do this ONLY if you are positive that there is no open flame, no electrical switches nearby, and the gas is turned off.

(1)Open the gas valve. When you hear a hissing sound, that means that there is a puncture in your gas tank and a leakage.

(2)Spray a 50-50 solution of water and dish soap using a spray bottle to the gas valve and the supply line and look for bubbles. If bubbles are forming around these connections, you would need to replace the gas supply line. If you see that leaks are coming out anywhere in the gas line, immediate replacement is a must.

(3)Call your service provider or a technician to do the next steps for you. If you can’t find the leak, they should be able to do so. You should never turn the gas on or use the gas oven until you are sure that there are no leaks coming from the connection lines.

When it’s time to buy a new one

Years of usage always equate to depreciation of appliances. Any of your appliances won’t last forever. Especially when it comes to kitchen appliances, you should always check if there are parts that need to be replaced, or if the whole unit needs to be thrown out. Gas ovens must be trashed when leakage can no longer be fixed. It is always better to be safe than sorry!

Are you noticing an unpleasant smell in your kitchen every time you turn on the oven? Is it a gas-like smell making you wonder if there might be an issue with the appliance or something else entirely? If so, don’t panic!

You may think it’s dangerous, but the most common causes of an oven smelling like gas are very easily solvable. This blog post will discuss why your oven produces this odor and how to solve the problem quickly and safely.

Why does my oven smell like gas

A gas smell emanating from your oven can be quite alarming. However, most of the time, it’s caused by a minor issue that can easily be resolved. The most common causes of an oven smelling like gas are:

1. Food particles left in the oven cavity

If food particles are left in the oven after cooking, they may start to burn and cause a gas smell. To avoid this, make sure to clean your oven after every use thoroughly.

2. Loose or worn gasket

The gasket is the rubber seal around the oven door. If it’s loose or worn out, heat may escape and cause a burning odor similar to gas. Inspect the gasket for any damage or wear and tear and replace it if necessary.

3. Pilot light out

Many older ovens have a pilot light that ignites the gas burner when you turn on the oven. If this light goes out, the gas will not be ignited and may cause an odor in your kitchen. Check to see if the pilot light has gone out; if so, relight it according to the manufacturer’s instructions.

Luckily, the most common causes of an oven smelling like a gas can be easily solved and do not require professional help or expensive repairs. However, if you still have issues or are concerned about any potential problem with your oven, consult a qualified repair technician for further advice.

10 Reasons Your Oven Smells like Gas When Preheating

If the oven smells like gas when you turn it on, the cause could be anything from a malfunctioning part to something stuck in the oven cavity. Here are ten common reasons why your oven smells like gas when preheating:

1. A broken or worn-out fan motor: 

The fan motor circulates air while preheating, so if it’s damaged, it could let gas escape. Check to ensure the fan motor is working properly and replace it if necessary.

2. A dirty burner: 

If you haven’t cleaned your oven in a while, residue from the last time you cooked could be burned off when preheating, causing an unpleasant smell of gas. Clean your oven and burners with a soaking solution to remove any residue.

3. A faulty igniter or thermocouple: 

The igniter and thermocouple are responsible for lighting the gas in your oven, so if either is malfunctioning, it could be causing an odor of gas when preheating. Test both components for continuity and replace any that don’t pass.

4. A damaged gas line:

 A damaged gas line can cause a leak, which would be the source of the smell. Check for signs of damage like rust or corrosion on the gas lines and have them replaced if necessary.

 5. An old oven:

A worn-out or outdated oven could be to blame for the smell. Check for cracks in the oven cavity and replace any worn-out parts if necessary. 

6. Blocked vents:

The oven needs to vent properly; if the vents are blocked, it can’t do its job. Clean out the vents of any lint or debris that might be preventing airflow. 

7. A malfunctioning thermostat: 

The thermostat is responsible for regulating the oven temperature, so if it’s malfunctioning, a rotten egg smell could cause an odor of gas when preheating. Check the thermostat for any signs of damage and replace it if necessary.

 8. A faulty gasket: 

The gasket is responsible for keeping hot air sealed in the oven cavity, so if it’s damaged, it could cause an odor of gas when preheating. Replace any worn-out or damaged gaskets to keep air from leaking out.

9. A clogged oven vent: 

If the vent is clogged, it won’t be able to properly circulate hot air and gas, which can cause an unpleasant smell when the oven is preheating. Clean the vent with a vacuum and replace any worn-out components if necessary. 

10. A blocked gas supply line:

 If your gas supply line is blocked, it can create an odor of gas when preheating. Check for signs of blockage or damage and have it replaced if necessary. Now that you know the most common causes of an oven smelling like a failing gas igniter when preheating, it’s time to figure out how to solve the problem and get your kitchen back to smelling fresh again! Read on for quick tips on stopping your oven from producing this odor.
