Beko, which has details of the affected cooker models on its website, said it attempted to contact more 21, 000 customers to warn them of the fault, but nearly 7, 000 had not been contacted.
In July LFB warned that up to 500, 000 fridge freezers could pose a fire risk after the brigade found that a fire at a tower block in Bermondsey, south-east London, was caused by a faulty Beko fridge.
