Ariston Control Circuit Power Loss

The oven light works but the display and controls are dead; the oven will not turn on.

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

Blown internal fuse on the control board, failed low-voltage transformer or power supply, loose neutral connection to PCB.

Safety first: Turn off power at the breaker before opening the control panel.

Access PCB: Remove the top or front panel to expose the main control board.
Check PCB fuse: Look for a small glass or ceramic fuse on the board. Test for continuity and replace with the same rating if blown. Investigate for short circuits before powering up.
Inspect connectors: Ensure all supply wires to the PCB are secure and not burnt.
Replace PCB: If the fuse is intact but there is no low-voltage output, replace the main control board.
