If the interior light on your Electrolux dryer is out, start with the simple stuff: the light socket is the top solution and is easy to test with a multimeter to see if voltage is reaching the lamp. If the socket has power, the next most likely culprits are the control components — the control panel, touchpad and user control/display board all house indicator lights and must be replaced as complete assemblies when their LEDs fail. Less commonly the door switch can stop sending continuity and prevent the light from coming on, and a damaged light assembly itself may need replacement. If other indicators are out or your dryer controls not working, treat the control board assemblies as likely suspects. You can test the socket and door switch yourself with basic tools, and once you know the failed part you can enter your model number on RepairClinic.com to find the exact replacement part for your dryer and step-by-step instructions to replace it.
01 - Electrolux Dryer Light Socket
If the light itself is newly installed or shows no signs of damage, yet still won't work, it's possible the light socket is defective. You can use a multimeter to test whether or not voltage is reaching the light socket. If the meter shows that power is reaching the light socket then it's likely the socket is malfunctioning and will need to be replaced.

The dryer door switch will turn the interior light off when the door is closed and turn it back on when the door is opened. If the switch is defective, it may be unable to allow voltage to reach the light. You can use a multimeter to test the door switch for appropriate electrical continuity when actuated. If the switch doesn't provide appropriate continuity, it will need to be replaced.
The most likely cause of a dryer interior light not working is a defective light assembly. Inspect the assembly for any visible damage or burn marks and replace as required.
