The cook top display show control lock ?i need to unlock

Display cleaning protection

If you wipe over the control panel while the hob is switched on, settings may be changed. To avoid this, the hob has a function you can use to lock the control panel for cleaning. To activate: Remove the twist knob. An audible signal sounds. The ? indicator and the hob settings flash. The control panel is locked for 10 minutes. You can now wipe over the surface of the control panel without altering the settings.

To deactivate: Put the twist knob back on within 10 minutes. The control panel is unlocked. To end the function early, put the twist knob back on before the 10 minutes have elapsed.

Two things to try. Either unplug it or turn it off at the breaker.. Clean the cook top control area and allow it to dry overnight. You can turn the power back on after cleaning ideally. In the morning, with the power resumed just wipe the control area off with your bare clean hand.

I have no idea why this worked for me, but it did. Good luck.
If that fails, you can look up error codes or schedule a repair.

Child Lock:
After switching on the control, the child lock function can be activated. To activate the child lock,
simultaneously operate the right and the left of the slider button and then operate the right of the
slider button again. "L" meaning LOCKED will appear in all heater displays and the control can not
be changed. (If a cooking zone is in the hot condition, "L" and "H" will be displayed in alternation.)
The hob will remain in a locked condition until it gets unlocked, even if the control has been
switched off and on.
To deactivate the child lock, first switch on the hob. Simultaneously operate the right and the left of
the slider button and then operate left of slider button again. "L" will disappear in the display and
the hob will be switched off.

To Unlock Cooktop: Touch and hold the CONTROL LOCK/
ALL OFF keypad for 5 seconds.

This means the oven lock is activated. The cook top touch panel is likely causing some problem.
Try to press the child lock button and see if F1 goes off. Otherwise the control panel will need to be replaced.

I just bought a bank repo home in So. Cal. that has the same Viking range as you have. Yes, the black lettering has almost entirely rubbed off. on this one too. Not good for such an expensive product.

I bit the bullet and ordered a new panel from appliancezone.com

http://store.appliancezone.com

Part # PE40057

The price is about $75, $80 with shipping, which is a ripoff I know.

I plan to put a clear coat of sealer on it and let my wife know to treat it gently.

I was surprised how many people think Viking products suck. Lots of negative reviews abound on the internet. If I was to buy a whole new range I think I'd avoid this brand.

To Unlock Cooktop: Touch and hold CONTROL LOCK for
5 seconds.

Great.. finally. i manage find from solution from user guide.. L is Locked. below is the instruction. will check out tonight. 
The locking function holds the current settings, or prevents anyone from starting the hob. It is also used for cleaning the control strip as the controls can be locked without the hob being on. To lock the hob : -Press the on/off button     . -Press simultaneously " - " button and " + " button of the front right zone (PVD 633 front left zone), and then press again on the " + " button of this zone. The hob is locked, the locking indicator " L " is displayed on all zones for 20 seconds. To unlock the hob : -Press the on/off button      . The locking indicator " L " is displayed on all zones. -Press simultaneously the " - " button and the " + " button of the front right zone (PVD 633 front left zone), and then press again on the " - " button of this zone. The hob is unlocked.

1. Turn off the power at the breaker box.
2. lift off the air grill.
3. remove the two screws at the front of the control switch panel (escutcheon)..
4. slide the control panel forward until it disengages, then lift up to expose the switch assembly and wiring.

Got the same problem, and remembered I've kept the manual book
L means locked. I dont know how Ive managed to do this as well

Anyway it says:

Cancelling the key lock
After switching ON the control the child safety feature can be deactivated. Here it is necessary to simultaneously operate the front right cooking-zone-select-key and the MINUS-key and then operate the MINUS-key alone. If all steps hae been carried out in the right order within 10seconds the key lock gets cancelled and the control is OFF. Otherwise the input will be considered incomplete, the control remains locked and switches-OFF after 20 seconds.

After a renewed switching-ON/OFF key all displays show 0", the display dots are blinking and the control is ready for ooking. If a cooking zone is "hot", "H" will be displayed instead of the static 0".


Followed their instructions & still not worked. ,I am still confused and baffled after these instructions........................
