ABSTRACT:
A system for indicating by means of at least one warning light the residual heat of at least one pan support grid for a gas burner in domestic cooking or heating appliances controlled by an electronic control device, in which the residual heat of the grid is measured indirectly by the electronic control device on the basis of data relative to the flame level set for the burner and the time for which said flame level is maintained, these data being corrected by a factor which takes account of the physical characteristics of the grid, such that the warning light is and remains activated when the residual heat of the grid exceeds a predetermined safety threshold (A) for its handling by the user.
