Electrolux EI30EF45QS 30 in 5.1 cu ft Built-In Electric Wall Oven with True European Convection MECH-LIGHT Error Fix: Oven Light Socket or Bulb Failure

The interior oven light does not illuminate when the door is opened or the light button is pressed. Check the light bulb first — use a 40W appliance-rated halogen bulb (standard bulbs may shatter from oven heat). If the bulb is good, check the light socket for corrosion or a broken contact. On Electrolux wall ovens, the light assembly is accessed from inside the oven cavity behind a glass lens cover. Check the wiring from the ERC to the light socket. Some Electrolux models use an LED light board instead of a traditional bulb.
