Our 10 year old neff U1421 has just gone bang and has blown the fuse and left a white/grey film covering the complete inside of the oven. Is this repairable and if so, what part/s do I need?

Sounds like the element has burned a hole through itself,, check with a local dealer for the element,, be sure to replace the contacts at the wires when replacing

    be sure and unplug the unit prior to working o n it,, and keep in mind that this model also has the thermofuse located in the back,, remove the rear panel to locate it

Our Neff U1421 double oven has a problem with tripping the main fuse when the main oven reaches 180 degrees. The oven is in manual mode not using the clock timer, can you throw any light on the proble

yes i know exactly whats wrong, one of your high accuracy temp sensors will have gone.
these tell the thermo what the sides & top of the oven temp is.
unscrew the oven from the base unit & pull it out, take the top off & you'll see them little round cylinder looking things with 2 wires coming off them(see link for pic) there screwed to the shell. the one that will have gone will no doubt have burn wires, or connections.
their sometimes called temp switch sensors

The bulb in the main oven no longer works. The problem is that we cannot unscrew the lamp cover, in spite of following instructions in the manual. How can we do this? It is a U1421 oven, approx 10 years...

Hello, I find that spraying pam cooking spray around the lamp cover and letting it sit for a while will help on removing that cover. Rember to clean the excess spray before using the oven...Hope this helps.

The fan is running but no heat,is it more likely to be the element or thermostat that needs replacing, also as oven is 10 years old is it worth just replacing

If the fan is working o/k, and the temp indicator is on, then it is safe to say that it is the oven element that needs replacing.
It is located at the rear of the oven compartment behind a removeable cover.
I would definately say it was worth doing if everything else is ok.
A new one is megabucks now.
Any more info, let me know.

Neff u1421 bottom oven: Either fan works but no

You need to replace the oven fan element, as there is probably a seperate element in use when used on convection heat.

Neff U1421 main oven trips the circuit breaker.

It might be that the breaker is overloaded and it's no longer supporting the load of all the appliances together.If you do not want to change your breaker you can still use your oven by switching off other appliances that is running while you are using the oven

Neff oven u1421 not heating up

If you have an Ohm meter, then test anything you feel is failed. No sense in replacing good parts.

I am surprised that there is no wiring diagram somewhere on the unit, like in the control head, or on the top or back (most units built in the U.S. over the past 30 years have them. Don't know about UK, which is where I assume you are.).

Let me know! The overload on the back should have a red reset button. The thermal fuse has to be replaced if it's failed, and normally when it fails, the control head will not work. It usually does not carry enough current to power the elements.
