Ariston Door Switch Logic or Wiring Issue

Oven cavity light does not turn on when door is opened, but works when manually switched on (or vice versa)

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

Faulty door switch, Miswired switch contacts, Control board input fault

Safety first: Isolate power before testing the switch.

Locate and test switch: Find the door switch on the front frame. Test all switch contacts with a multimeter in door-open and door-closed positions.
Correct wiring: Ensure wires are on the correct switch terminals (common, NO, NC) according to the wiring diagram.
Replace switch: If contacts are unreliable, install a new door switch.
PCB input: If the switch is good but the oven does not respond correctly, the control board input may be faulty and require replacement.
