How to bypass broken clock on eurolec 720ef electric wall oven

Normally, there is a master switch on the wall near the oven. This is in turn is usually fed from its own fuse/breaker on the consumer unit. I suspect this has bblown.

It looks like the clock has failed. Try leaving the power off for at least 10 mins, turn it back on at the main switch and then try it. If it still doesn't work Espares can get you a new one. Incidentally, if there is power to the oven, the grill will work even if the clock is not set.

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.

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.

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?

Looking at the circuit diagram, it appears that there is a problem with the programmer. There is a contact that operates in it to provide power to both top and bottom ovens. The feed for the grill is prior to this contact, which explains why this is still working. Is the clock/programmmer set correctly? In some ovens, if the clock is not set then the ovens do not work. You should be able to hear the realy operating when the clock is set. If you need a copy of the handbook then if you supply an email address, I will send you a copy.

No, there is no reset button. However, the grill will only work when the front is down as there is a microswitch which operates to provide connectivity when it is in this position. This is to stop the grill overheating. The switch could have gone faulty.
Does the top oven work ok?
When you operate the grill there are two options, part or full. Are they both failing? Does the cooling fan switch on when either grill is operated?

I have a Stoves Newhome EL716 double electric oven and last night, it just lost all power and stopped working - no grill, oven, lights, clock or anything. Can anyone tell me what this could be please? Thank you.

there is a safety stat/fuse on top of the oven exterior i think you will find that it also has blown. Make sure you have isolated the appliance at the fuse board first though, Good Luck

The grills appear to be independant of each other. Does the oven still work and the oven light come on?

Depending on your answer it could be that the Top Oven Switch has gone faulty. The Grill Regulator and the Switch work together on the top oven. To get at both you will need to take the top of the oven off.
