Viking double oven gone electrically dark
Diagnosed as a control board failure the same day the call came in — the part itself still took longer to source, and we said so up front.
The Call
What We Hear
The display and controls aren't responding at all on one or both ovens, even though power is getting to the unit.
A common way this fault gets described to us
Viking double oven — control path
Both ovens run off one control board, which is why a single failure can take out either one.
Control board
Not powering the display or relays
Power supply to the unit
Full voltage present at the terminal block
Heating elements, both ovens
Continuity confirmed once the board was replaced
Door switches
Both closing and reading correctly

The Diagnosis
What Was Actually Wrong
Root Cause
Control board failure taking out both ovens at once
This model runs both ovens off a single shared control board, which is exactly why a failure here reads as "the whole unit died" rather than one oven acting up — neither side can respond without it.
Power was present, both heating circuits were intact, and the door switches were fine — everything pointed at the board itself rather than a wiring or element fault, which is why the diagnosis was confirmed on the first visit even though the part had to be ordered in.

If This Is Happening To You
Control board?
Both ovens dark at once?
On a double oven sharing one board, that pattern usually means the board, not two coincidental element failures.
Power present but nothing responds?
That combination points at the control board rather than the supply — worth mentioning on the call.
Same-day diagnosis, longer part wait
Control boards on premium ranges usually aren’t van stock — we’ll tell you the timeline at diagnosis, not after.
Don’t keep resetting the breaker
Repeated power cycling doesn’t fix a dead board and can mask what a technician needs to see on arrival.
A same-day diagnostic on a control board issue still often means a multi-day wait for the part itself — we tell you that up front, not after the fact.
