Viking Induction Cooktop Code 1 flash (with brief interval): Power Device Overheated

What 1 flash (with brief interval) means

On Viking induction and radiant cooktops that report through an LED instead of a display, such as the VICU165-6B and VCCU105-4B, one flash followed by a brief pause means the internal power device is over temperature. The same table applies to the VIRT301 and VCRT301 rangetops. The cooktop reduces or stops heating to protect itself, and the LED flashes to tell you why.

Common causes of 1 flash (with brief interval)

Cooling airflow around the cooktop restricted
Cooking at high power for a long time
Cooling fan or vents blocked
Power device running hot

✓ One safe check you can try

1. Turn all zones off and let the cooktop rest for 30 minutes. 2. Make sure nothing blocks the vents or the space under the cooktop. 3. Switch the breaker off for a minute and back on. 4. Restart at a medium setting. 5. If one flash returns quickly, call us.

! Why to stop there

The power device is under the cooktop
Cooling checks mean removing the unit
Repeated overheating shortens the life of the electronics

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.

1 flash (with brief interval)1 flash (with brief interval) questions

Is one flash serious?

It means the power electronics got too hot. A rest period often clears it, but if it repeats quickly the cooling around the unit or the electronics must be checked.

Can cabinet space cause it?

Yes. If vents or the space below are blocked, heat builds up. Keep storage clear of the cooling path under the cooktop, so a rest period is worth trying first, before you book a visit.

How soon can you check it?

Tell us it flashes once on the LED. We give a written price before work, and our repairs carry a 30-day workmanship warranty, because the vents and the space below the cooktop must stay open for cooling.
