The stats fail on them, you should hear a click as you turn it, if not it's failed.
There's also a thermal fuse inside but it's crimped in.
Uneconomical to pay someone to repair really.
There about 30 pound and theres a newer version that has a blow fan.
Got this convection heater . It's stopped working. Tried changing plug's fuse to no avail. Will I have to buy a new one or can it get fixed?View attachment 288789
