My SMEG gas oven won't stay alight. When I stop pressing the oven regulator the gas goes out.

Hi, it is your thermocouple. It's worth having a look first prior to getting someone to replace it though. You will see a small "probe" that sits in the flame which is the thermocouple, this is the fail safe device that cuts off the gas should the flame go out. When it heats up it keeps the gas on but when it cools (when the flame goes out) it will not let any gas through unless you have the knob held in. Three checks:

• look at the end of the probe and see if it's sitting in the flame, it may have been knocked to one side during use or cleaning which will prevent it working - gently push it back into place and try again.
• Has the probe become covered in grease etc which is preventing it working properly - clean with a rag and try again.
• Is the end of the probe heavily corroded - if so will need replacing.
• Sometimes they just get tired so will require slightly longer to warm up and hold. When you light the stove hold the knob in for 15 seconds and see if it holds then.
