How do I set auto timer on my neff oven to come on In a couple of hours ?

Firstly, make sure the actual time is correct. Set the oven (if it's a double oven the clock function will only work on the main oven) to the setting and temp required. The first timer setting you put in is the cooking duration (not the start time) ie if it's a casserole that you want on low for a couple of hours, adjust the first setting to 2:00, when you press for the next setting you will see the the timer has already added 2hrs to the current time, adjust this to the time you want the item to finish (eg, You want it ready for 6pm, adjust to 18:00). Don't press anything else, give it a second or two and the oven will switch off. The oven will switch on 2hrs (or whatever time you have set) before the end time. Whilst the oven is waiting to switch back on, on some models the cooling fan will run continually, this is normal. If you are a little slow enter the times the clock will time ut and return to the actual time.
Hope this helps

Make sure the oven is set for 'manual' start cooking as opposed to 'automatic'. Usually you have to press a button on the timer.

have you accidently set the timer to auto?

1. Set the oven to the required
temperature.
2. Press the g button.
3. Set the total cooking time with the +
button (see the example in the
illustration right, showing 1 hour and
30 minutes).
4. Press the h button.
5. Set the cooking finish time with the +
button (the example in the illustration
shows 12.30 hrs.).
After setting the display shows the
time of day and indicates »AUTO«.
❑ The oven cooling fan will start
immediatley.
❑ At the pre-set time, the oven will be
automatically switched ON.
❑ The settings can be corrected at any
time.
❑ When the pre-set cooking finish time
is reached, a signal sounds and the
oven is automatically switched OFF.
To turn the signal off, briefly press the
h button.
6. Turn the oven selector switch to the
0 position.
7. The »AUTO« symbol blinks.
Important: It must be switched OFF
by pressing the E button.

Also here is the manual.

Good Luck

If it is a digital timer and u have display, thenyou must make sure it is set to manual and not flashing auto, or the oven will not work.
If it is an anologue timer tweak the knobs until you can see a hand symbol showing this is the manual mode.
If no display of any kind, and u are sure u have a supply to oven then timer could be faulty.
Hope this helps.

U must ensure that u have a supply to the oven befor trying to alter timer.
Plz rate solution.
Thanks.

Hi.
Is it flashing AUTO, If it is and you can'y reset it back to manual, then you have faulty timer.
Hope this helps

You need to rest the timer. to get it off auto,otherwise the oven will not work.
Refer to your instructions.

hi there if your toc is at fault you will have no oven function at all ie. fan, light, and timer display. i would first check your timer is not set to auto and is also got the time set, failing that your thermostat may be at fault.

hi there switch your oven off at the mains switch for one minute thenswitch back on and set the time this will disable the auto on the timer.
