Hiya,
Can you post the model number of the appliance please?

Have you tried turning the power off for 10 minutes, turning on and setting the clock from a fresh start?

If not, can you try that?

Thanks

Hiya,
OK, thanks for that.
We'll see what happens when you try setting the clock this time.
Hopefully it will work

Let me know the outcome.

Thanks

No, the duration light comes on still when I set the clock and the oven will not come on

Expert:  Techdesk replied 3 years ago.
Hiya,
Thanks for that.

Assuming you've done it correctly (I think you will have as you are following the instruction book) it points to a faulty clock/timer.

If you have good diy skills it would be possible to bypass the clock so the oven works.

How are your diy skills?

Thanks

Hiya,
OK, isolate the power to the appliance and gain access to the rear of the clock and it's wiring.

To gain access, you need to take the top of the cooker off and slide it rearward, you don't have to unplug it or disconnect wiring, simply release it and slide it rearward.

Screws should be at the underside of the top, at the rear, you may need to take the side panels off to get to screws on the side.

Take the screws at the rear holding the top out.
Slide the top forward a little to release it at the front, lift and move it rearward so you can get to the timer.

Once you get to the timer and it's wiring, look at the wiring and the connections they go onto.
The connections should be marked on the circuit board.
Let me know the markings.

If not, take a photograph of the rear of the timer and it's wiring, then post it here.

Thanks

Hiya,
OK, thanks for that.

I can't see the markings but the brown wires on the right are the connections you need.

You need to take them off and join them together electrically.
Insulate and then reassemble the machine.

The clock will still come on flashing so you can set the time.

The oven should now work as the clock/timer no longer controls it.

Hope this helps
Thanks

I did as you suggested but the duration light is still on

Expert:  Techdesk replied 3 years ago.
Hiya,
Yes, it will always be on.

There's no change to the clock and it's display.

What you've done is bypass the clock so the oven works manually.

Have you tried the oven?

This isn't a fix for the clock, it's a fix for the oven.
If you want a fully working clock and timer, you need to replace the clock.

no i am afraid not

Expert:  Techdesk replied 3 years ago.
Hiya,
OK, does anything at all happen when you try the fan oven?

Thanks
Customer: replied 3 years ago.

No nothing but I notice a connection is off it is a green and yellow wire, would you like a picture?

Expert:  Techdesk replied 3 years ago.
Hiya,
Green and yellow is an earth wire, it will have no effect on the operation.

I don't think the fault is with the timer, as bypassing it would have got this working.
The symbol you have up may be the manual symbol?

Take the top off again and look at the switch for the main oven.
Find the marking P2 on the switch body.
Follow the wire from that connection back and it comes to a cut out thermostat.
Temporarily bypass the thermostat by linking the wires together.

Try the oven.
Does it now run?

Thanks
Customer: replied 3 years ago.

No I am afraid you are loosing me now.

Expert:  Techdesk replied 3 years ago.
Hiya,
Sorry, lost you at what point?

Thanks
Customer: replied 3 years ago.

I cannot see a marking p2

Expert:  Techdesk replied 3 years ago.
Hiya,
OK, take the switch out and look closely at it, the markings are there at the side of the contacts or on the underside.

Thanks
