If your Roper refrigerator light not working, start simple and work down the list in the order most technicians would: the light assembly can fail and some models require replacing the entire assembly, so check that first; the bulb may simply be burned out, so swap it before doing anything else; a defective dispenser control board can cause a dispenser light to be out but is less likely, so inspect the board for burn marks and use a multimeter to check for voltage at the connector; if the board checks out, test the fridge light switch and the door switch for continuity with a multimeter and replace any switch that does not pass; finally, test the light socket for power — if the socket is getting power but the bulb still won’t light, replace the socket. Whether your fridge light not working, refrigerator interior light not working, or the refrigerator light out, you can enter your model number on RepairClinic.com to find the exact replacement part and step-by-step parts and wiring diagrams for your Roper model.

While it's not a likely cause, a defective dispenser control board could be responsible for a dispenser light not working. You can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to determine if the board is sending voltage to the dispenser light's plug-in connecter. If no voltage is present, you'll know the board is defective and will need to be replaced.
To determine if the door switch is defective, use a multimeter to test it for continuity. If the door switch does not have continuity when activated, replace it.
To determine if the light socket is defective, use a multimeter to determine if the socket is getting power. If the socket is getting power, but the light bulb won’t work, this indicates that the light socket is defective. If the light socket is defective, replace it.
While it's not a likely cause, a defective main control board could be responsible for a refrigerator light not working. You can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to determine if the board is sending voltage to the light socket or plug-in connecter. If no voltage is present, you'll know the board is defective and will need to be replaced.
