The clocks blank and both of the ovens arent working but the hobs and everyting else are

Hi, Have you altered the time clock on the cooker? It is possible that the clock/timer is set for 'Auto'

The double oven will only work if a time is set on the clock. Any time will do, you just have to set a time. The grill/top oven is independent of the clock. If the clock is faulty espare can sorce them for you.

The electronic clock/timer must work correctly and be in manual mode for the oven to work. It sounds as if you need to replace the electronic clock. If you do not need the clock function it is fairly easy to bypass the clock altogether and the oven will work no problem.

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.

Beko DV 555w Electric cooker.Oven and clock is not working.
The hob and grill work.

The hob is normally totally independent of the oven. What is actually working or not working on the oven? i.e. does the grill still work, is the clock OK and can you set it, or is everything totally dead?

the ovens work through the clock auto contacts if the clock not working then the ovens wont. may need a new clock or you can bypass the timer relay contacts if your clever. one of the oven elements may have blown to earth this is the main reason for a clock failing

There are possibly a number of options. It could be that in wiring the hob in you have disturbed the wiring for the oven. Normally the oven works off the main oven control switch on the panel and the hob could be wired into something else.
Is the oven totally dead no power at all for everything, or is the clock running but the oven will not switch on?

MY CANNON CAMBERLEY main oven is not working at all. No Gas, no ignition, hobs are okay, clock is blank.

Hope this helps with your dual fuel version 3 weeks on and working perfectly! Rangemaster 110. Ovens not lighting due to faulty auto/clock. FIXED! Our clock /timer kept flashing and would not reset
Someone, somewhere on the internet had the solution to my problem but I can't find the link again to thank them! If you don't mind losing the clock/timer auto function this is for you and it's free! Just takes a bit of time.
Basically you need to lift/open up the LH &RH hobs to get at the wires behind the clock. You should see 2 blue(neutral) wires coming directly from the back of the clock. Pull them out and connect together - should be easy to click them together. Then the ovens will light - but you will lose the auto/clock/timer functions. We only used the timer so not a big issue. We didn't take the control panel off but we did take ages to unscrew the hobs etc Probably took us about 2 hours going back to instruction manual we found on internet and trying to work it out but I think we've saved a lot in not replacing the unit with the usual call out charges. We made sure electrical supply was switched off and just took our time. Really chuffed!

This should allow you to see the instruction manual for the 110. There was another one somewhere showing a diagram of how to link the 2 blue wires at the back of the clock but I can't find it again! By the way our cooker is 10 years old so maybe different from newer models. We didn't have to take of the front control panel we accessed everything by lifting up the hobs to get behind the clock/timer.

Hope this helps! Ovens still working just got to go and buy a wee timer.
