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

I have recently had a problem with my free-standing Belling Cooker Model No. G775. The inner glass on the main oven door shattered on the draining board whilst I was drying it after washing it. I had not had the oven on so the glass was completely cold. It was a frightening experience – just like an explosion and pieces of glass were thrown at force everywhere up to 8 foot and into the adjoining room. My particular oven does not have a self cleaning system and I try to wipe the oven door each time after cooking so preventing any buildup. Also I do occasionally take the glass out for a thorough wash.

I telephoned the manufacturer to report this but was told that these things do sometimes happen and the risk was probably made worse by the age of my cooker – 9 years and not old in my estimation particularly as it is cleaned and well looked after. They quoted just under £100 for a new glass which included package and carriage. After much discussion we decided to replace the cooker as we were really concerned with what had been said about the glass deteriorating with age. We are both in our mid seventies and did not wish for a repeat performance.

The Manufacturers informed us that they had a customer loyalty scheme whereby they were willing to
replace with which ever cooker I decided from their range at a discounted price and were pleased to be offered a replacement Belling Cooker at more than £100 cheaper than any other retailer. We ordered a Belling FSG60DOP.

Imagine our horror that when the gas-safe man disconnected the old cooker the day before our new one was delivered the outside glass of the top oven also exploded showering small pieces of glass once again. We spent a sleepless night worrying about taking delivery the next day of a similar Belling cooker and worrying about the glass on the new one. I phoned manufacturers next day to tell them about this second panel breaking and was told again that these things do happen and it was probably caused by the gas-safe man lifting the old cooker by the handles to pull it out. I cannot confirm that this is what happened.

We have now received our replacement cooker and at the moment am very concerned about a same thing happening with the glass doors as they look very similar. It is nearly impossible to buy a cooker without these complete glass doors – we have tried.

We actually had some peaches on the work top when the first glass shattered and we found a piece of glass embedded in one of the fruit – that could have been someones eye !!

We have a Leisure RCM 10 CRK double cooker. The actual outer oven door (not the two panes of glass inside) has exploded whilst I was cooking a Roast beef dinner. We’ve had the oven for 5 years. Quite scary when it happened glass everywhere all over the kitchen floor. I’ve not used abrasives on it. My husband and I are trying to figure out what could cause the main door to explode like that.

Ann-Stress particles in the glass could build up if the door is constantly slammed shut over a long period otherwise large changes in the temperature due to an oven cleaning facility which heats the glass up to danger level, again over time . If it was just a case of a flawed glass it would have gone before 5 years.

Nice to thank the people for contributing their stories – though for Mick the type of oven would be interesting. Rather like washing machines the problem seems to be aggravated by having glass in the door. Accepting people want this then perhaps the size of the viewing aperture is a problem as glass becomes bigger.

I wonder what the last Which? survey has revealed on breaking glass in oven doors. There must have been time for it to be analysed since it was in Spring 2015 and I mentioned it here in May.

Assuming 20m ovens in the UK this provides an idea of the replacement rate
“The impact of the project can be assessed through examining the volume or value of ovens sold in the UK each year. Approximately 1.5m ovens are sold on the UK market annually. The commercial cost of this is estimated at almost £600m. Therefore, with 25% of the market previously exploiting the tolerance, the cost of goods affected by the project is in the region of £150m.

To quantify a saving to the consumer, UK consumers were spending £700,000 more per year on their utility bills than they might have done had they had access to accurate product information regarding their oven’s performance and chosen the more efficient appliance. Consumers should now be completely confident the oven they are buying performs to the standard manufacturers are declaring on the energy label.”

The claim in the final paragraph is interesting as one assumes that getting to temperature quickly etc would mean less overall cooking time and that this is a potentially bogus £700,000 consumer detriment.

I would be very happy to have a washing machine with a metal door. The only benefit of having a glass door in my current machine is that I have watched laundry detergent capsules and bits of tablets becoming trapped in the door seal and still there during the rinsing process. 🙁

It would be nice to have the option of buying ovens and washing machines with metal doors. I expect they would appeal to anyone who had suffered an explosion.

Our parents turned out fantastic dinners with metal oven doors. They knew when to open the door for a quick look at the roast or the cake. I have no objection to a window in the door but I think it introduces another point of weakness and potential safety hazard.

just had the outer glass oven door explode. I opened the oven door to clear up any glass and the inner glass exploded, looks like the outer glass was supporting the frame of the door.
No injuries just a couple of shaking dogs, awaiting manufacturer to contact us.
Cooker is less than a year old

Paul we have just had a similar experience with a 9 month old Hotpoint oven and am awaiting an engineer… I’d be interested to know how you got on seeing as yours was under a year old too? Thanks!
