However, there is no red, orange, or yellow hot electrodes glow during the electrode preheating mode, indication that the electrode are not warm enough to glow during the preheating. This is also happen when programmed starting krypton T5 fluorescent lamps (At least with the 54W krypton T5 lamps in my father home's kichen).
