I have this heater https://www.manutan.co.uk/en/key/beldray… The red power on and off switch lights up for a split second when turning it on then goes off. Fuse works fine. Is 13a in 13a plug.

Hi, Is there a model number on the appliance? The specs state that it has an adjustable thermostat and overheat protection and also a thermal cut out device so any one of these may be the problem
