Air fryers are certainly quite the trendy appliance at the moment. They’ve revolutionised home-made chips and nuggets, crisping them up without frying. But one Kmart shopper was devastated when she discovered that the appliance had damaged her kitchen.

Kmart sells a range of air fryers – ranging from a compact 1.5-litre air fryer for $49 to the larger 7-litre air fryer priced at $119.

One Kmart shopper shared an air fryer warning on a facebook group after she discovered that her Kmart Air Fryer had cracked her kitchen bench top, as reported in 7News.

Just an FYI and warning!” she wrote on the Kmart facebook group.

Bought the big air fryer and have been loving it … till I noticed a big crack in my bench top.

I didn’t realise the heat the air fryer made underneath and has now cracked my stone bench top!

Air Fryer Warning: they aren’t all what they’re ‘cracked’ up to be

The woman said that the heat that was released from the bottom of the appliance had damaged her stone kitchen benchtop.

She shared a photo of the counter, showing a long crack in the stone. The woman said the damage had left her husband “quietly rocking in the corner”.

Read The Manual People!

No many of us actually thoroughly read the manual when getting a new appliance. If this shopper had, she would have seen that the instructions recommend consumers to place the air fryer on an insulated heat pad, or at least a surface that is heat resistant.

To be honest, I would have thought a stone benchtop would be heat resistant so I would have done the same thing as her. But apparently, even though most stones are heat-resistant, they can be damaged by sudden and rapid surface temperature changes.

A restoration expert explained:
“Stone countertops are susceptible to cracking under surface heat. The reason for this being that heat on the surface doesn’t spread through stone, so when the area underneath the fryer begins to expand (as all things do under heat), the rest of the counter does not, so that resulting pressure can cause fractures. It’s a natural factor of using stone or other natural material, there’s always a weak spot or a fault somewhere. Just because it hasn’t happened to you, doesn’t mean it doesn’t happen.”

And laminate benchtops are just as susceptible.
“Be careful if you have laminex bench tops too. Heat on laminex will make the laminate bubble up in a big blister. Not repairable, new bench top. We used to replace quite a few where people used an electric kettle in one spot. Appliances that get hot should be placed on a heat protective mat or board, in fact you should use a board for anything on your bench top, they also get scratched or cut.”

She Got Crucified

Other air fryer users practically fried the poor woman for sharing her experience, saying that she should have read the instructions more carefully.

“It pays to read instructions, common sense really not to put something that generates that much heat directly on any kind of bench, sounds like some could have saved themselves a lot of money,” read one comment.

“It’s not a warning she needs to put out it’s called read instructions and this would not of happened in the first place that’s why things like this air fryer comes with a instruction manual!” said another.

I ALWAYS Follow Instructions

Many shared that they always place a mat below their appliances.

“It’s common sense to always put something underneath your appliances even if its a toaster a sandwich press deep fryer or air fryer.”

“With anything that generates heat that I put on the benchtop, including the slow cooker and pie maker, I ALWAYS put it on the breadboard. I had my husband make me an extra thick board for this particular purpose,” one said.

“When we bought our air fryer the instructions said to put it on a board as it generates a lot of heat and can damage stone bench tops,” another said.

Happens Regularly

However, it seems this unfortunate incident is certainly not the first to happen. In fact it seems it’s quite common for air fryers to cause major heat damage.

“My $200 air fryer cost me another $1,400 for a new Cesar stone bench top we had only been in our new house 2 years a very expensive lesson read instructions first,” shared another air fryer user.

“A friend has an acrylic back splash in her kitchen & her air fryer melted it too.”

“Our air fryer blows from the back and it heated the tile the tiles fell off and the timber behind them was burnt so we soon tossed it to the tip and went back to good old fashioned cooking in the stove.”

  • I know this is close to a year old now but glad I found it as this was one on the more cheaper air fryers on out list. Might do more research now.


  • I’m glad I saw this article as my mum recently bought one so I have let her know to be careful!


  • WOW! I never knew that this could happen to a stone bench top. I am shocked. I will remember to always place something underneath hot appliances.


  • I must admit I have a stone benchtop and I thought it was invincible. However I always put a board or heat tile underneath my appliances but that’s only so the bench stays clean. Never realised that could happen and, I will admit, that I rarely read instruction manuals all the way through. Just read how to use the item.


  • Always a wooden chopping board under any heat source on the bench. You never know how hot something will get on the bench. Hubby always makes sure I do this.


  • I can’t believe this. I have shared this with my hubby who now puts our Air Fryer on a wooden chopping board.


  • Glad i read this before investing in an air fryer!


  • Eek that’s frightening! I wonder if that advice is for all brands? I have a Phillips airfryer and cannot recall reading that advice!


  • Oops, good to know.


  • I’ve always used a board under my appliances, I don’t have an air fryer but if I did I’d still put a board under it just incase as I have granite tops.


  • My daughter has the original kmart airfryer (I think it is like 3.5 litres or there abouts) and while the bench was fine (she has a stone bench) it did melt the cover of her electrical power point and she had to get a new cover. She now pulls it out from the wall a bit an there has been no problem since. As for putting it on a board, I would think that would be a recipe for a fire. I have always put my “hot” appliances directly on the bench without any trouble (and I have many of them). I don’t personally have the kmart fryer but the Phillips one I do have gets plenty hot but has never cracked, burnt or melted anything. These appliances are designed to sit on the bench. If I was going to put anything under them (and I won’t be) it would be a silicone mat that won’t burn. A bread board or cutting board (wood, bamboo or plastic) is a terrible idea IMHO.


  • Gosh that is scary


  • That poor person! I dont have an air fryer. I am a pretty minimal gadget person.


  • I hate to break it to the Kmart lovers but I have a Philips air fryer which I use on a laminated surface and no damage ever- Kmart brand is obviously poor quality.


  • I always put my brad board underneath when using it.
