An oven with a self-cleaning function is quite a convenient appliance to own. However, the self-cleaning process can take up to 5 hours to complete. So, is it safe to run that cycle while you go to bed?

No, it’s not safe to self-clean an oven while sleeping, and you should never do that. A self-cleaning oven poses an increased fire and injury risk. It also produces smoke, fumes, and carbon monoxide throughout the process. You must always be awake and present at home while self-cleaning an oven so you can maximize ventilation or shut it off if a problem emerges.

This guide will help you understand how the self-cleaning process works and what risks it poses. Don’t worry, though! You’ll also learn how to use the self-cleaning function safely and enjoy its benefits.

How Does Oven Self-Cleaning Work?

There are a lot of safety aspects to explore regarding self-cleaning ovens. However, it’ll be incredibly helpful to first understand how these kinds of ovens function.

The self-cleaning feature that you can find on many ovens these days works in a very straightforward way. When you turn it on, it causes the oven to heat up to extreme temperatures of more than 900 °F.

In doing so, the extreme heat incinerates all leftover food residue and grease in every corner of the oven’s compartment. All that’s left behind will be ash that you can clean up quickly with a damp cloth after the process is complete.

Again, all of that is only possible when the oven reaches extremely high temperatures.

Unfortunately, those temperatures come with their fair share of risks, which you’ll dive into deeper in the following sections of this guide.

How Long Does It Take For An Oven To Self-Clean?

The self-cleaning process doesn’t just involve extremely high temperatures. Besides that, it also requires several hours to complete, typically lasting 3-5 hours depending on your oven brand and model.

Those hours don’t include the preparation time beforehand and the cooldown process afterwards, which typically adds another hour to the overall duration.

All that time required to complete the self-cleaning process is another reason why it’s risky.

Is It Safe To Self-Clean Oven While Sleeping?

No, it’s not safe to self-clean an oven while you sleep. 

As you’ve seen above, the process involves heating your oven to extreme temperatures above 900 °F for at least 3-5 hours.

As such, the process comes with its share of risks. That’s why you must be present and awake while it runs. That way, you can respond quickly if anything goes wrong.

Here are some of the dangers associated with your oven’s self-cleaning process:

#1 Smoke And Fumes

The first reason you should never self-clean an oven while you sleep is your oven might fill your house with dangerous smoke and fumes.

Remember: your oven generates extreme heat to burn all food residue and grease to ashes, making all of them quick to clean later on. As you might imagine, that incineration process creates at least a little bit of smoke and fumes.

Unfortunately, the smoke and fumes can be much more intense in an oven that’s dirtier than average.

That’s why you must be awake and present at home so you can maximize ventilation when necessary. Of course, that could be as simple as turning on the hood or opening the windows and doors.

#2 Potential Injuries To Children And Pets

The extreme heat caused by the self-cleaning process doesn’t just stay inside the oven. The oven’s outer panels and the window will also become dangerously hot.

That will cause injuries to children and pets that might touch the oven while self-cleaning.

By staying awake throughout the process, you’ll be able to protect any children and pets you have at home.

#3 Increased Fire Risk

Next, there’s also the increased fire risk. As you saw in #2 above, both the interior and exterior of the oven become extremely hot while self-cleaning.

Besides that, any leftover grease inside the oven could also ignite as it self-cleans.

Small flashes inside the oven are normal. However, if an out-of-control fire breaks out, you must be there to shut the oven off, control the flame, and call emergency services if necessary.

The fire risk of a self-cleaning oven is real, and there are plenty of news stories that show you shouldn’t underestimate it.

#4 Carbon Monoxide Poisoning

Self-cleaning ovens are known to also pose a carbon monoxide risk. Carbon monoxide is a harmful gas that’s odorless and colorless, posing an extreme danger to anyone in your home.

Again, staying present during the self-cleaning process and maximizing ventilation allows your oven to self-clean safely.

How To Safely Use Your Oven’s Self-Cleaning Function?

Despite the dangers listed above, enjoying your oven’s self-cleaning functions is still possible. You just have to take the necessary precautions to minimize any risks.

Here are some ways you can self-clean your oven safely:

Stay Awake And Nearby

First and foremost, you must stay awake and nearby throughout the self-cleaning process. That way, you can respond to any problems by quickly shutting the oven off and maximizing ventilation in your kitchen.

Wipe As Much Grease As Possible 

Yes, the self-cleaning process is supposed to take care of the mess inside your oven by itself. However, you can help it do so safely by wiping up as much grease as possible beforehand. That way, there’s no chance of excess grease igniting and starting a fire.

Lock The Oven Door 

Most newer oven models will lock the oven door automatically while self-cleaning. However, you’ll have to lock older ones manually.

In either case, double-check that the door is locked when self-cleaning begins. That will prevent kids, pets, or anyone else from opening the door and experiencing the extreme heat inside.

Maximize Ventilation

The self-cleaning process will generate smoke and fumes. However, the exact amount of smoke and fumes can be hard to predict, so you should maximize ventilation in your kitchen regardless.

You can start by turning on the kitchen hood if you have one. Also, if possible, open your kitchen window and door, and keep a fan on.

Even if your oven produces very little smoke and fumes, excellent ventilation will prevent those emissions from causing breathing difficulties for you or anyone else at home.

Let The Oven Cool Down Completely 

After the self-cleaning process ends, you must still let the oven cool down completely. That will ensure that you don’t accidentally burn your hands when trying to open the door or clean inside the oven. 

Remember: the bigger your oven, the more heat it will retain. So, you’ll need at least an hour or more to let your oven cool down completely.

Frequently Asked Questions (FAQs)

Here are a few additional questions and answers to keep in mind when self-cleaning your oven safely:

What Happens When You Self-Clean An Oven?

When you self-clean an oven, the appliance will generate extreme heat to incinerate any food residue and grease left inside. The temperatures will reach 900 °F or more and last 3-5 hours, turning everything to ash so you can wipe it all away quickly later.

Can Self-Cleaning Ovens Catch On Fire?

Yes, self-cleaning ovens can catch on fire. Firstly, the process generates extreme heat inside, which will ignite any leftover grease. Excess grease can lead to a fire starting inside the oven. Besides that, the oven’s external panels will also become extremely hot, potentially igniting anything flammable that comes in contact with it.

What Happens If You Leave The Racks In A Self-Cleaning Oven?

Your oven racks are not designed to withstand the extreme temperatures of a self-cleaning oven. As a result, when you leave them inside, they will warp and bend, becoming too damaged to use again later on.

Is It Safe To Be Inside While The Oven Self-Cleans?

Yes, it is safe and necessary to be inside your home while the oven self-cleans. However, you need to monitor the oven and shut it off if any problems emerge. In addition, maximizing ventilation will prevent any breathing problems. 

So, turn on your hood and fan while keeping your windows and doors open whenever possible.

Can Fumes From A Self-Cleaning Oven Hurt You?

Yes, excess fumes from a self-cleaning oven can cause breathing difficulties, especially if you already have breathing issues. However, you can minimize the fumes in two ways.

Firstly, ensure that you wipe up as much food residue and grease as possible before beginning the self-cleaning process. That will reduce the intensity of fumes while self-cleaning.

Besides that, keep your kitchen well-ventilated at all times. Open your windows and doors, even if only a little. That will make a significant difference in maintaining air quality.
