Since our gas oven was cleaned recently it has failed to relight after the oven door has been opened during cooking. The oven will relight if the door is left open and the oven left to cool down for 2 to 3 mins and the temperature setting then put high.
The oven cooks at the right temperature when the door is closed and the oven is lit.
The oven is a Creda Europa double oven model no 48132.
