in your fuse box.
The appliance has a safety temperature controller that shuts the
appliance down if it overheats. After the cause has been removed
(for example air outlet or inlet apertures covered) and the appli-
ance has cooled down for a few minutes, operation starts again.
If you cannot remedy the fault, notify your qualified contractor.
