Etna No Power to Control or Blown Internal Fuse

Etna range clock and display are dead; oven and cooktop do not work.

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

Tripped household breaker, Blown internal control fuse, Loose mains terminal block, Failed power supply on control board

Safety: Turn off the breaker before opening any panels.

Check breaker: Verify the range circuit breaker is ON and not tripped.
Inspect terminal block: Remove the rear cover and check for loose or burnt connections where the power cord connects.
Internal fuse: Locate and test any fuses on the control board. Replace only with the same type and rating.
Control board: If fuses and wiring are good but there is still no display, the control board power supply may have failed and the board must be replaced.
