Viking Induction Cooktop Code 7: voltage supply missing a leg

What 7 means

Code 7 on Viking Professional VICU206 and VICU266 induction cooktops, hybrid VCCU106 and VCCU166 models, and the VISC530 induction range is a voltage supply error. The most direct cause is a missing L2, the second line of the 240-volt feed, though a loose cable, a defective filter board or a defective power board can also trigger it. Zones may not heat and the 7 appears.

Common causes of 7

Missing L2 at the cooktop: one pole of the breaker tripped or the line not reaching the unit
Loose supply cable
Defective filter board
Defective power board

✓ One safe check you can try

1. Find the cooktop's double breaker in the panel and check that both halves are on. Switch it fully off, wait a minute, then fully on. 2. Check that other 240-volt appliances nearby still work. 3. If code 7 stays, stop using the cooktop. Do not open it or test the terminals; a lost line needs a licensed look.

! Why to stop there

A missing line can be in the house wiring or in the cooktop, and finding which takes meters
Terminal and board checks involve live power

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.

77 questions

What does L2 mean?

A 240-volt cooktop is fed by two live lines, L1 and L2. If one is missing, the cooktop gets only half its supply and reports code 7.

Can a tripped breaker cause code 7?

Yes. A double breaker can trip on one side, leaving a line dead. Reset it fully off and on once; if it trips again, stop and call.

Is code 7 always a cooktop problem?

No. The missing line may be upstream, in the supply cable or connection. We check the supply first so you do not pay for a board you do not need.
