We have a delonghi DTC 90 G FSD gas oven that is constantly turning itself off, it will only be on for a short period of time before this happens, and will need to be continuously re lit which is ruining food.

SOURCE: Oven shuts off by itself

When your oven reaches the desired temp. it shuts down then turns back on again after it cools down a couple of degrees and cycles like this during the complete baking cycle. If your ignitor or oven valve is getting weak it would cause this symptom.

I had the very same problem. I slid the oven out of the wall about 6" or so, unplugged it, plugged it back in. It worked. I'm not sure if I jostled some connection, or if unplugging/repluging it in reset some sort of circuit fault.

I have a gas Tricity Bendix Country Cottage oven. The grill and the hob work perfectly but the oven won't light properly. The gas initially lights but then doesn't fire up properly, so the oven is warm but not hot and means I can't cook anything, can I fix this myself?

Hi,
If your electric oven is not heating then you probably have a bad heating lelement in your oven. This is not that hard to fix yourself...

Hello there and thank you for choosing fixya
This is a fairly common issue with these ranges
See what happens it that over time the electronic touch pad begins to wear out or stick and then it will eventually stick in the pressed position even though you will be able to press the touchpad the internal part of the touchpad is what is sticking thus giving you the continuous beeping noise this could also be a indication that the whole electronic range control is begining to fail . this is all part of the touch pad ok?
So i would recommend that you contact your nearest appliance dealer and see if they can get you a new electronic range control they are fairly easy to remove and replace ok?
Please keep me posted on how this is going ok?
Best regards MIke
