Tecnogas Electrical Interference / Shared Neutral Issue

Oven interior light and display flicker when a burner ignites or when the oven cycles.

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

Loose neutral connection, Shared circuit overloaded, Failing control board filter capacitors

Safety first: Turn off power before inspecting wiring.

Steps:

Inspect the terminal block and neutral connection for looseness or discoloration; tighten and repair as needed.
Ensure the range is on a dedicated circuit as recommended by Tecnogas.
If wiring is sound, the control board may have degraded capacitors causing flicker and may need replacement.
