Frigidaire Professional Interior Light Failure

Dishwasher interior light (if equipped) does not turn on when door is opened.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Burned-out LED or bulb, Faulty door switch, Loose wiring to light assembly, Control not supplying power to light circuit

Safety First: Turn off power before accessing any wiring or light assemblies.

Check door switch: If the dishwasher also does not start reliably, the door switch may be faulty and should be tested and replaced.
Inspect light assembly: Access the light (often in the upper tub or door) and check for visible damage. Replace the light module if burned out.
Verify wiring: Ensure connectors to the light are secure.
Control board check: If the light and switch are good but no power is supplied, the control board may have a failed light circuit.
