Viking Induction Cooktop Code 2: knob switch input error

What 2 means

LED code 2 on Viking Professional VICU206 and hybrid VCCU106 induction cooktops points to the knob switch, meaning either its wiring or the way the switch operates. The same table is used on the VICU266, VCCU166 and the VISC530 induction range. The control is receiving a knob signal it cannot read correctly, so you may find a zone ignoring the knob or the cooktop showing the number 2.

Common causes of 2

Loose or damaged wiring to the knob switch
Knob switch not operating correctly

✓ One safe check you can try

1. Turn every knob to off and wipe around the knob bases with a slightly damp cloth, since sticky spills can hold a knob in place. 2. Shut the cooktop's breaker off for about a minute and restore it. 3. Turn one knob and watch whether the 2 returns. 4. If it does, stop using the cooktop and call us. Leave the knobs and glass top in place.

! Why to stop there

The switch and its wiring sit under the glass top, so the repair needs a proper teardown
Replacing a switch by guesswork can leave the real wiring problem in place
We give you a written price first and back the work with a 30-day warranty

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

22 questions

What part does code 2 point to?

It points to the knob switch circuit: the switch itself or the wiring that carries its signal to the control. Both are checked on the cooktop before a part is recommended.

Can I keep cooking on the other zones?

If the other zones respond normally you can, but a switch problem can behave unpredictably. We would rather you stop using the cooktop until it is checked, especially if a zone will not turn off.

Will cleaning the knobs clear the code?

Occasionally, when spilled food is jamming a knob. If the code comes back after cleaning and a power reset, the switch or its wiring needs repair.
