Has your oven door shattered?

shattered oven

We’ve all heard about exploding washing machine doors. In fact, a few years ago, the Which? Convo community helped us compile hundreds of examples of exactly that happening. But what about oven doors?

Recently, a number of you have told us about the alarming experience you’ve had of your oven door shattering or even breaking explosively onto the kitchen floor. And in some cases, as with washing machines, the oven wasn’t even being used at the time.

One member wrote:

‘A few weeks ago, I went to open the bottom oven door to put away some baking trays and, as I touched the handle, there was a loud bang and the door shattered into a thousand pieces on the floor. Gave me a real fright. I had used the oven about 3 hours earlier so it was quite cold.’

Another said:

‘The oven had been on cooking a roast and was cooling down. I was in the kitchen when there was a loud bang and I felt something hitting the back of my legs. When I looked around, the outer oven door was shattered, with small pieces of glass scattered around the kitchen with a pile of small pieces lying on the floor underneath the oven door. We measured that the small pieces had travelled 11 feet from the oven door.’

But mostly, the oven has been cooking, when the incident has taken place:

‘Today, without warning and whilst cooking a roast meat joint, the inner glass door exploded forcing open the outer glass door and ruining the roasting meat and making a huge bang and depositing minute pieces of glass all over the kitchen floor.’

Are any brands worse than others?

When we looked at shattering washing machines doors in our May 2016 issue, the brand Beko cropped up more often than you’d expect, considering its market share.

But so far, when it comes to ovens, no particular manufacturer stands out – in fact, more than 20 brands are on the list from Which? members’ experiences.

So what’s causing oven doors to shatter? While we’ve never had an oven door shatter during our testing, we are currently gathering information from oven engineers, industry experts and manufacturers on why oven doors – inner or outer – might shatter.

So far, potential culprits include:

  • incorrect positioning of glass after cleaning
  • use of abrasive cleaning materials that score the glass
  • build-up of grease causing the oven to overheat
  • glass has been knocked
  • a wet towel hanging on the oven door
  • a dish touching the inside of the door while cooking

Over to you

While it’s unlikely that your oven door will shatter, if it does, it isn’t something you’ll forget in a hurry.

So, we’d like to hear from you if the glass of your oven – whether part of a cooker or a built-in oven – has ever shattered or exploded.

Let us know what happened, including any response from the manufacturer. And if you’ve taken any pictures, please send them to conversation.comments@which.co.uk


This has recently happend to me, and I am shocked at the responses people have expressed from the manufactures. I wonder has anybody taken legal action against any of these manufacturers?

My outer glass on oven door exploded today. No idea why, the oven was cold and I had removed the inner glass to clean it. I closed the door and 5 mins later it completely shattered. New World are sending an engineer.

Our oven was installed in January 2017 by a Howdens contract kitchen fitter. My wife opened the oven door on Saturday 22nd December to check on the burgers she was cooking in the oven and there was a loud bang. The inner glass simply shattered as she opened it, which gave her quite a fright, but thank goodness she was not injured Luckily the shattered glass was retained in the oven door. I had recently cleaned the oven 2 days ago and as far as I am aware I had replaced the glass correctly after cleaning it. Lomona gives advise as to what not to use to clean the glass, but no advise as to what to clean the glass with. I did not use a harsh aggressive detergent, cleaning powder cream abrasive cleaner or a sharp metal scraper or a liquid cleaning agent with acid or chloride. I believe this to be a fault in the manufacturing process. Beko whom I believe are the makers of the supposedly heat resistant glass for the oven doors have had ample time to rectify the problem and in my opinion should replace the glass free of charge without question. I shall be contacting Howdens tomorrow for a replacement..

Hi John ,
Sorry to contact you .I just wondered if you ever heard anything from Beko or Howdens regarding this issue ?
The reason I ask is we have recently had the same problem.
Kind Regards

Our Beko oven door has just exploded as well. Also 3 months old. We will see how the suppliers respond on Monday.

I hope no one was hurt. Do let us know how you get on.

Also a Beko. Inner glass door exploded when unpacking the brand new oven before any use.

This has happened *twice* to our virtually unused Britannia range cooker, once in July and now today. It’s now out of warranty but they’ll still send the new glass for free. I asked what would happen if it happens a third time and there was a bit of waffle about ‘escalating the matter’.

My Glem Gas Oven has just shattered the inner oven door for the second time. It’s about 5 .5 years old and has occurred twice. Low use of Oven as its just my husband and I cooking nowadays
Seriously this is very poor performance. I have had other Ovens for years and never seen this before. SO I have email company but nothing coming back??

IKEA oven door explodes sending shards of hot glass all over family kitchen
Mum Emma Clark has hit out after the less-than-a-year-old Whirlpool oven detonated saying it was lucky the children weren’t in the room
The full article in the Mirror is here: https://www.mirror.co.uk/news/uk-news/ikea-oven-door-explodes-sending-18323085

As shown in the photo of the oven, the glass has broken and produced many small pieces, showing that it is toughened glass. One of the reasons that toughened glass is widely used is that it does NOT produce shards and is unlikely to cause serious cuts.

Toughened glass can shatter or explode (due to stored energy as a result of heat treatment) but it does NOT detonate, since no combustion is involved.

If the Mirror wants to do something useful they could push Ikea and other companies to offer ovens with a metal outer door, especially those models with a self-cleaning function, since this involves a very high temperature and increased risk of glass breakage.

The picture tells a different story.

If the glass door exploded, why is there a reflection of a bare foot?

The majority of the glass is inside the oven and it looks like some of it fell out when the door was opened, so more likely something shattered inside the oven.

Something just doesn’t ring true with this.

I agree. The inner glass shattered (it doesn’t “detonate”), the outer glass is intact, and some pieces have come “out through the bottom”; it would be interesting to know where that gap is. It is unlikely they would have had sufficient velocity, taking that route, to cause direct injury.

Nevertheless, an unpleasant experience. Thermally-toughened glass rarely spontaneously shatters, so the IKEA statement ““a tendency to explode” is rather misleading. It is important when handling or cleaning toughened glass not to damage the edges or scratch the surface as this can cause breakage, not necessarily immediately.

I’d agree a rather typical newspaper report.

We have glass doors to view the cooking progress, so a metal door would be less useful.

It seems odd that anyone should be wearing bare feet when there is broken glass on the floor. I cannot see why the fragments of glass landed on the floor if the outer glass is intact. Maybe the door had been opened.

For many years I had a Belling cooker with a metal door and a glass inner door that was easy to remove for cleaning. I expect that anyone who had experienced a shattered door would be keen on this option.

My wife had a small Toyota hatchback some years ago – the model which has as its rear door/window a single piece of toughened glass. On the second day she had it, she drove to a local shop, and as she opened the rear door/window the glass shattered explosively. Toyota made it all good, of course, but the roof needed a respray.

Today our Hoover HOA54VX built-in oven inner pane glass shattered. Our oven is a pyrolytic self cleaning oven with triple glazed door. The oven was on and cooking at 180 degrees. From our living room we heard an almighty bang … the glass exploding. Glass shattered into tiny pieces and went everywhere when we opened the oven door. We have had the oven for just over two years. I called Hoover Candy Customer Care and they seemed disinterested and tried to sell me a domestic and general repair plan. I now have an email address for their escalation’s team who deal with “statutory rights” claims… Will see how I get on!

My indesit oven door has now shattered twice in the space of 5 months, both times during the night when it’s not been on. Indesit fixed the first time but have not been helpful the second.

Our Lamona oven inner glass exploded on Wednesday night. No idea why! Unsure whether to replace the glass or get a new oven completely. It seems like it’s more brands than we initially thought!
We are really careful with our oven – do not slam the door as the post above suggests. We get our oven professionally cleaned once a year (he doesn’t use any abrasives, nor do we) and keep on top of it in between.

Lamona is a brand of appliances installed in kitchens fitted by Howden. Spares may be available from various sources online and replacement may make sense, particularly if you can do this yourself. If you go for a new oven, don’t forget the cost of removal/disposal of the old oven and fitting the new one.

Plenty of replacement inner door glasses listed online, and inexpensive. No reason to replace the oven if that is the only problem.

My Lamona oven inner glass just exploded as well. Hasn’t even being used during the day. We are renting the property for less than 3 months and the appliance was new. Gave us a right scare!

I hope your landlord will have the glass replaced promptly, Laura. It’s usually an easy job.

Just happened to my Hotpoint outer oven glass door. Seems quite common!!!! Intend to contact manufacture and supplier. 22 Dec – Hope OK for the turkey etc!!!!

Bought a Corbero Mini oven week before Xmas.Was fine. Sunday Feb 2nd heard noise turned around to see the outer glass door had shattered.Was in use at time.The oven area to all sides were clear
Shop no joy there said glass not covered by guarantee.No joy with Corbero or Euronics either.

HI Chris – I suggest you have a look at this information on the Which? website: https://www.which.co.uk/consumer-rights/advice/what-do-i-do-if-i-have-a-faulty-product#was-a-fault-present-at-purchase Ignore the guarantee and make a claim against the retailer under the Consumer Rights Act, which provide you with statutory rights. Within six months of purchase the fault is assumed to be present at the time of purchase, so unless the company can prove otherwise (e.g. by providing evidence of misuse) you are entitled to a repair or other remedy.

If the retailer denies that they have any liability I understand that they are ignoring the requirements of the Consumer Protection from Unfair Trading Regulations 2008. It would be a great help if Which? would confirm this.

Ah but bought this in Spain.So will I still get anywhere.

As far as I know, your rights under the Consumer Rights Act would not apply to goods bought in other countries.

Correct, it is UK law. There may be similar provisions in Spain of course. It may be best to get a spare inner glass yourself – if one is available.

Some information here on the cause of breakage https://www.which.co.uk/news/2017/09/exploding-ovens-why-glass-doors-shatter-and-what-to-do-it-if-happens-to-you/

BEKO, if I remember correctly, dominate the market in shattered doors but the reason has not been pursued.

Thank You all. Now just written to Spanish Consumer Comlaints in Spain. No heard yet.

My 5 months old Beko freestanding oven door exploded on its own. Was not being used. I have written to Beko.care to see if they’ll fix it under warranty.
Any tips welcome thanks.

Two weeks ago my oven door came off in my hand. Looks like it was one of the hinges had bent with the heat. I could still clip the door on so continued as normal then last night I Was making a roast chicken for dinner, removed the door and the glass burst into a million pieces on the floor, making crackling noises for a good 10 mins after it happened! It’s a Hotpoint stand alone cooker. Any advice please as I don’t have the cash at the moment to buy a new cooker & my freezer is bursting with stuff that can only be oven cooked

We have a Lamona 3701 Pyrolytic Oven where the glass has just shattered during the cleaning process. Whilst it is still just under guarantee and an engineer is coming out to replace the glass I will be reluctant to use the self clean programme again. I feel these models should be recalled as dangerous.

In November 2019 we purchased a NEFF oven through a kitchen fitter. It cost in excess of £835. The retailer fitted the oven and we’ve used it 2 or 3 times a week with no problems until today, August 3rd 2020. This morning, my wife decided it was time to run the manufacturer’s recommended oven self-cleaning programme. Before starting we followed the guidelines concerning the removal of side rails and the other required preparations then set the cleaning process in operation. About 30 minutes later, the inner glazed surface of the windowed door shattered. The earliest a NEFF engineer can attend to replace the door is 2 weeks from now. Is it normal for NEFF ovens to provide only 9 months of moderate use before failing?
