Cant fix the clock to work without the timer - Neff B1421 Electric Single Oven

Hi,

Please use tools to unscrew the top portion of the dial from the oven and check if the buzzing stops. If not, then you might need to remove the entire dial/timer from the oven and work with a watch shop to fix the timing function of the removed oven clock. Or you can request the clock specialist makes a home visit in order to fix the oven timer/clock for you instead.

Thank you.

I assume the display for the clock/timer is now blank. If the oven is still working the only thing you are missing is the clock. If you can't do without it you will need a new clock.
Most of the time the clock/timer stops working it affects the operation of the oven, the oven won't work. If this is the case you will need a new timer unless you can do without the clock/timer. If so a repairman should be able to bypass the clock with ease so that the oven will operate without the clock/timer.

Yes, it is simply matter of bypassing the clock/timer so that the oven thermostat will have permanent power going to it all the time. It is a matter of removing the active and load wire at the rear of the timer and joining them together.

Both the top and bottom oven will only work if a time (any time) has been set on the clock. Setting the time operates a contact to switch the power through. The only exception is the grill. This will work even if the time has not been set. So if the oven controls/lights and heating work, to me it means that the clock/timer is half working and the only thing that isn't is the display.
I haven't had the clock/timer to bits but a fellow blogger has said that in some timers there is an electrolytic capacitor that controls the display. When this fails as they are renowned for doing, the dispaly mal functions. If there is one then Maplin have some - VHR41W/43W and DT64U depending on value etc. Let us know how you get on.
If you need a new clock/timer they are around £80 from espares.

I HAVE A ZANUSSI ZCG7690XN DOUBLE OVEN. THE CLOCK IS NOT WORKING AND I CANT USE THE BOTTOM OVEN EVEN THOUGH THE IGITION IS SOUNDING IT WONT LIGHT. I CAN STILL LIGHT THE TOP OVEN AND THE RINGS FINE. PLEASE CAN YOU HELP. AWAIT IN HOPE. REGARDS MO

Without a model number, my guess would be a stuck relay in the electronic clock/timer. Replace the Electronic clock/timer.

Picture of the oven and clock please or, is the clock digital or analog?

The part that needs replacing is the clock timer.

FIRST: ISOLATE THE CIRCUIT.

The front fascia is held on by three clips. Take off the two knobs and gently pry away the fascia fron the left, right and top centre.

The clock timer is held in by four plastic push clips at the top and bottom about 1cm in from the end. Push them in and pull the timer out.

There are now three wires on push clips attached at the back.

Do not take the colours for granted. On my oven just repaired the Live was Black and the Neutral was Red! The black marked 'C' is the input. The side by the trip switch is the output. The Red goes on the other side.

When the timer trips it causes the circuit between the input and output to break.

You have two options now:

Read the serial number of the timer and try and order it (expensive), swap the cables over.


Carefully run an electrical cable between the push clips on both black cables making sure you leave no exposed wire. Your timer and clock however will never work, the oven just does not care about it anymore.





Note: I am not an oven engineer, I am an electrical engineer in another field and have tested voltages and current and believe this to be safe. I have done this on my own oven.

Hi, My Competence B1180-4 digital clock keeps switiching itself off and then back on. This means that the timer etc dosen't work. It is intimitant.

its a fix more than a solution but you can bypass the clock thus allowing the oven to operate again
unplug at the mains and remove the oven from the housing remove the two fastening screws from the metal lid on the top of the oven ,and remove the lid
you will see the timer back panel with 3 wires coming to it, 2 are black (switching line) and 1 is red (Live feed to timer )
If you pull the connectors from the 2 black wires from the timer board and connect the ends together using a connector block, the timer switch becomes inactive and allows the oven functions to operate again.
you will have no timer functions but its a cheap fix and who uses the timer any way
good luck Andy B
ps if anyone has a set of operating manuals for ths oven i would be glad of a copy
