If your Roper dryer light is out, start by checking the bulb and the light socket: a bad socket can stop voltage from reaching the lamp even when the wiring looks fine, and you can verify that with a multimeter. If the socket and bulb test good, the next most likely causes are electronics in the front panel—indicator lights are built into the control panel, touchpad, or user control and display board, and those assemblies often have to be replaced as complete units when their lights fail. A faulty door switch is less common but can prevent the interior light from getting power, so test its continuity while actuating it. A damaged light assembly is also a possibility, so inspect for burn marks or broken contacts. If you need the right replacement part, enter your dryer model number on RepairClinic.com to pull up the exact light socket, control panel, touchpad, user control board, door switch, or light assembly that fits your machine.
01 - Roper 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.
