Tecnogas Unstable Oven Flame / Flame Sensing Issue

Gas oven ignites but then goes out after a few seconds or cycles on and off too frequently.

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

Dirty oven burner ports, Misaligned burner, Weak igniter not maintaining proper current, Low gas pressure

Safety first: Turn off gas and power before removing the burner.

Steps:

Remove the oven bottom panel and flame spreader to access the burner.
Clean burner ports with a soft brush or compressed air; do not enlarge the holes.
Ensure the burner is properly seated over the orifice and aligned with the igniter.
If the igniter is old, consider replacing it, as a weak igniter can cause poor flame stability.

If the problem persists, a technician should check gas pressure and the oven safety valve.
