Neff U1421 main oven trips the circuit breaker.

I have a built in Neff U1421 which is about 5 years old but it has started tripping the ring main circuit breaker each time I switch the main oven on. The light comes on OK but as soon as I turn on any heat settings, it switches off the electirc supply.

I have recently cleaned the oven but this has not caused any problems in the past.

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

Hi I have a 4year old Lamona 4601 double oven, the top oven/grill works fine but when I turn on fan oven it trips the power on the main house fuse board.


When the main breaker trips it indicates current is escaping from the circuit to ground.
If it is a micro-circuit breaker that trips it indicates the circuit is consuming too much current - a short circuit.

Either way the wiring or the oven elements have a fault and need attention.

No power to oven (MCB tripped but has now been reset on) but temperature light to small oven glowing faintly. If any control is turned on then this glowing light goes out. Any Ideas?


Check the bulbs in main oven. Bulb blows and takes out circuit board. A new circuit board will set you back £250 to £300. It can possibly be repaired if you can solder. need to take out the board behind the clock and find the blown track. if you can solder a jumper across it you can get it working again and it will cost you nothing. I had to do this to mine and it has been working for last 3 years.

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

My Neff U1421 bottom oven has failed.


Probably the ring element. If the clock is flashing zeros or 8's the bottom oven will not operate but the top will. Make sure the clock is set (doesn't have to be the correct time, just not flashing) If the fan and light then work but no heat, defo the element part no 499003

No heat in main oven, fan is working ok as is top oven. main oven was working ok then power was lost due to circuit breaker tripping??


You need to replace the oven element.
This is located at the rear of the oven compartment, behind a removeable cover.

Neff U1410 main oven trips the main RCD. Occurs


I have a u1421 with the same problem! I notice the fan doesnt run too well, sometimes it doesnt run at all, needs a prod to get it running. I suspect with no fan, that the element gets far too hot, and then starts to leak to earth, tripping the RCD. I'm gonna try buying a new fan motor - you should ckeck if your fan is running full speed OK.
