The fan oven that has stopped heating up is one of the most common problems that oven repair & cooker repair engineers are called to.

The problem in most cases is simply a faulty fan oven element. To call out the manufacture (CDA, Delonghi, Diplomat, Hygena, Elba, Kenwood, Tecnolec) to replace an oven element is going to cost you in the region of £75 – £125.

Here are the 3 main faults to look for in your oven or cooker that is not heating

If your Oven is not getting hot or heating up it could be a faulty element, if the fan in the oven is running and the thermostat light is on, this will lead us to believe that the element has gone faulty.

When you turn the oven on the household electrical supply trips on the Rcd (this is the earth trip in the fuse board) your fan oven element has gone to earth and needs replacing.

Your oven will not work until the clock/timer has been re-set after replacing an oven element.

Note that in some cases the fan oven element fails and it will trip the consumer unit’s rcd (this is the earth trip in the fuse board). If so then it needs to be re-set, but if every time you turn the fan oven on it keeps tripping then this could be a faulty element that has gone to earth.

The following symptoms should be apparent when testing your cooker:

  • Make sure your timer is not on auto.
  • Check to see if Fan oven is not heating up,
  • Check to see if fan in the oven is working fine,
  • Check to see if thermostat light is on.
  • On removal of the Fan Oven Element (see below) there may be visual signs of burning, blowing, or splitting but not in all cases. Is no sign of damage you will have to test with a meter.

    I have a DeLonghi double oven. The lower oven is an EDF 495 ST and it seems the power is not getting to it. The top oven works fine as does the clock/timer, but when I turn the knobs for the bottom oven it is just dead. I have powered down and back with no change. I also removed the panel to look for any obvious disconnected wire (or dead mouse!) but found none and was able to check the red power wire was live with a tester screwdriver. I was wondering if there is a fuse or something else I should check before getting help. Thanks.

    I have a CDA double oven and the bottom oven is heating up but sticks once it reaches 175 degrees,so it’s taking an age to do chips,jackets,etc..
    It worked after I took the fan casing off and re-fit a few days ago but it’s now doing it again.
    The element was glowing red,the fan is working and the thermostat was fine so I’m guessing it’s a faulty thermostat?
    Any advice would be greatly appreciated! Thanks
