Neff oven wiring diagram

It does not really matter which wire goes where. The red one would be live and the blue would be neutral, but on an oven element they could go on either terminal. Just make sure that everything is turned off when working on the oven etc.

I have changed the element on a neff u1661 main oven but still doesn't heat up. I noticed that one cable is loose possibly the earth?.the top oven and light and clock all work. Any suggestions please.

Is the loose cable on the element , if yes ISOLATE THE APPLIANCE BEFORE REMOVING PANELS
Usually they are spade terminals remove the affending connection, with a pair of pliers carefully press the terminal into itself, not too hard, it will be hard to put back on the element, move the terminal from side to side and ease on with continuous pressure. while you have the back off if you have a multimeter switch the mains back on, use extreme caution select A/C voltage above 250 volts, switch on the oven the fan will start to blow measure across the terminals, if you get a reading of 230 volts A/c the element should start to heat up. If no voltage, send me a reply.
Hope this has been helpful

We are having a neff oven U15M62NOGB fitted. The wires in the booklet are earth on the left, live in the middle and neutral on the right. Is this correct as the neutral and live are the other way round on...

Yes, the installation instructions are correct. The wiring from your old oven isn't relevant.

Your query is a little confusing though. The new oven should have a power cable attached to it for connection to the mains supply. This should be on a separate circuit from your sockets and connected to an isolator switch. The wires in the power cable are colour coded to ensure that they are correctly polarised when connecting to the mains supply. I'm assuming you're in the UK as you list a GB model number, therefore, it should have a BROWN wire for LIVE, BLUE for NEUTRAL and GREEN/YELLOW for EARTH.

If your house wiring uses the old red (live) and black (neutral) colour coding, then you just need to ensure that the brown (live) wire from the oven lead is connected where the red wire from the supply is terminated. The blue (neutral) wire should be connected where the black wire is terminated and the green/yellow (earth) wire should be connected where the green wire is terminated.

Internally, the oven probably uses red cable for live and black for neutal, but you really shouldn't need to be doing anything with the internal wiring to install the oven.

You say you are having it fitted. Any competent installer would know (or check) the correct wiring order even if the instructions were missing. If you are installing it yourself, be sure are certain you understand what to do before attempting this and double-check the power for the oven circuit is off before you start.

When replacing an element in a neff oven, what should I do with the earth wire? There's no point on the new, replacement element to which I can attach it to. Do I just wind a bit of insulating tape around...

So long as you make it safe, it does not matter if it is not connected, as the element will still be earthed via the cabinet earthing connections.
Please rate my solution.

What is the wire conection sequence

If there is no earth wire to the element, then it it does not matter which wire goes on the terminals of the heater, as they are common, so,as long as you do not connect the wires to earth, it will be o/k.
If one wire is green/yellow, then that goes to rearth.
Hope this helps.

I am just about to disconnect our old oven and have found the live and neutral and am fine with how they connect but am a little unsure as to how the earth will connect to the small earth tab on the new...

You may need to get a wire connector to install on the ground (earth) wire, so it can be connected to the terminal connection point on the new oven.

If one wasn't provided with the oven, some do this as a service, just look at the ground terminal or in the bag with the instructions, etc. for one. If not, you should be able to purchase one, you'll just need to get one that fits the wire, so knowing the gauge of the wire (either Awg or Kcmil size) will make this easier to get the right connector size.

I recommend that a ring terminal be used, so in the event that the fastening screw might loosen, the ring terminal will not fall off the contact point, whereas a fork terminal could and can come off much more easily.

Not having more detailed info about the brand and where you're located, makes further possible solutions difficult to provide, since Fixya doesn't require requestors to provide any info on what country they're in, etc.

Nonetheless, I hope you find this Very Helpful and best regards!

Apart from the main supply to the cooker terminals

So long as the earth is connected to the earth terminal, then there is no prob for you to worry about.
The normal twin and earth cable is adequate.

HI Zuso,

Use your original wire and hook up Left to right Line Neutral, and Ground. L N G. Black wire is Line. Green wire is Ground. not sure what UK uses for Neutral. I just know that you need a big wire. And the voltage is supposed to be 220-240Volts.
