F3 on a Viking gas wall oven means an open temperature sensor circuit.
Model compatibility: Viking reuses codes across series and model years, so F3 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
An open oven sensor or sensor circuit; the manual says to check sensor resistance and wiring.
Meaning
The oven sensor on a VGDO271 connects to the electronic range control (ERC). F3 says that circuit is open, so the signal path is broken between sensor and control. The self-diagnostic lists it as a temperature sensor malfunction, with short rapid beeps for more than 16 seconds.
Checks in the manual
Turn the oven off and unplug the sensor harness from the ERC.
Read resistance at the connector. About 1100 ohms at 75F is expected.
If the value is high, take the sensor out of the oven and measure it alone, which separates the sensor from the harness and any poor connection.
The manual adds that resistance rises when the sensor is held in the hand. Because this uses a meter and an unplugged harness on a gas oven, it is not a do-it-yourself reseat.
Your part
Record the code before touching anything, and make sure it is F3 and not F4.
Try OFF/CANCEL or a power disconnect, which can clear some F-codes.
If F3 recurs, stop using the oven and call a servicer.
F3 is an open oven sensor or sensor circuit. The manual names sensor resistance and wiring as the checks, with about 1100 ohms at 75F as the expected reading.
