Beko KDC655K gas oven lights but will not stay alight

The problem

The gas oven on a Beko KDC655K lights, then goes out straight away and will not stay lit.

Likely cause

Most strongly supported diagnosis is that the flame safety device is not being satisfied. The discussion says this usually points to the thermocouple or flame-sensing arrangement, with a faulty gas valve magnet mentioned as a less common possibility. A weak or uneven flame, blocked burner holes, poor burner seating, or dirt/grease around the sensor area were also suggested as possible contributing factors.

What fixed it

First check that the oven control knob is being held in long enough after ignition, as releasing too quickly can cause the flame to go out. Also check whether the flame properly reaches the sensor and whether the burner area is clean and unobstructed. If the flame is good and the knob is held in sufficiently but the oven still drops out, the discussion points to the thermocouple as the likely fault. As this is a gas appliance, further diagnosis should be carried out by a suitably qualified appliance engineer. The thread was marked solved, but no completed repair was confirmed.

Checks to try

• Hold the oven control knob in for several seconds after ignition
• Check whether the flame properly envelops the thermocouple tip/flame sensor
• Check for a weak, patchy or one-sided flame
• Check whether burner holes are partially blocked
• Check whether the burner is seated correctly
• Inspect for dirt, grease or corrosion around the burner and sensor area
• Check whether the appliance is still under manufacturer warranty
