A Kmart shopper has issued a warning to air fryer users after an unfortunate incident left her kitchen bench top permanently damaged.

Sharing on a popular Facebook group, Serene said she was stunned to discover that her Kmart Air Fryer had cracked her kitchen bench top.

“Just an FYI and warning!” she wrote on the Kmart Hacks & Decor 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!”

In the product instruction manual, Kmart does advise that the appliance should only be used on a “stable, horizontal, flat and heat resistant” surface and ‘placing the air fryer on an insulated heat pad is recommended.’

Kmart told the Daily Mail that they are committed to designing great quality products for their dedicated customers.

‘At Kmart, we’re committed to designing and creating great quality products for our customers; and we’re proud to offer families a wide range of cooking appliances.’

‘Air Fryers are one of our most popular appliance categories; with a 5-star customer rating and dedicated fan page on Facebook with over 398,000 members’, a Kmart spokesperson said.

‘When it comes to electrical appliances, we recommend customers familiarise themselves with the safety precautions outlined in our User Manuals. This will ensure products are used correctly.’

‘Placing air fryers on dry, level, stable, and heat-resistant surfaces (away from overhead cabinets or presses, which may be damaged by steam) is recommended,’ the Kmart spokesperson said.
