RCA range oven light will not turn on, but oven heats normally.

Safety first: Turn off power or unplug the range before replacing the bulb to avoid shock.

• Replace bulb: Remove the oven light lens (usually by turning counterclockwise) and replace the bulb with the correct type and wattage specified for your RCA model.
• Inspect socket: If the new bulb does not work, inspect the oven light socket for corrosion or burnt contacts. Replace if damaged.
• Check switch/relay: If the socket is good, the light switch (on manual models) or control board relay may be faulty. Test continuity of the switch or output from the control and replace the defective part.
