The recall of the AM04 and AM05 models was issued by Dyson after “a small number” short-circuited, causing a small internal fire, Belfast Telegraph reported.
The British company stressed that other models are unaffected and no one has been injured as a result of the fault.
In a message posted on its website, Dyson is urging customers to return the products for a free engineering fix.
“We’re voluntarily recalling all AM04 and AM05 heaters due to a potential safety issue.
“Out of a million heaters sold worldwide, we know of a small number that have short-circuited resulting in a small fire within the machine.
“There have been no instances of injury or property damage, but safety is our first priority.”
