Whirlpool is reissuing an urgent recall of its tumble driers.
Whirlpool says hundreds of thousands of tumble dryers which could cause a fire are still being used in people's homes around the UK.
An urgent recall was issued for 500-thousand machines in July - but only 65-thousand owners have come forward.
The company is now reissuing its warning.
The dryers were made over 11 years under many different brand names including Hotpoint, Creda, Proline and Swann.
You can check if your drier is affected here.
If you think you've bought a potentially dangerous dryer you can call 0800 151 0905.
If it is on the recall list, the advice is to stop using it and unplug it immediately and call Whirlpool for it to be taken away.
