F04 is a non-critical code: probe cooking stops, but the oven can still operate.
Model compatibility: Viking reuses codes across series and model years, so F04 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The meat probe input is shorted, and cook-by-probe operation is cancelled (priority B, non-critical).
A minor code
Most oven fault codes stop the oven. F04 does not. Viking’s EOC4 sheet marks it priority B (non-critical), so only the affected function is dropped and the oven can still be used. The function lost is cooking by meat probe.
The fault
The entry reads “Meat probe, shorted.” The probe input is seen as shorted, and any cook-by-probe operation is cancelled. The sheet does not list other functions as affected.
Where it appears
No range light pattern is given; the lights are marked not applicable. The code is therefore reported on wall ovens with a TOD2 or TOD3 clock.
Clearing F04
Correct the short. The sheet adds no more detail.
Re-enter the timed or delayed function afterwards.
Until then, cook with time and temperature rather than the probe.
Neighboring codes
NO PROBE is the opposite problem: the probe is missing or unplugged, and the oven flashes the NO PROBE, COOK and UPPER or LOWER OVEN icons.
F21 is another non-critical code, for shorted keys on the TOD2.
