Viking Oven F3 Error Code
On ERC5800-based Viking oven controls, F3 is documented as an open sensor or sensor circuit.
Content status: Reviewed — wording follows cited Viking service literature; confirm decode on your exact model.
F3 decode from Viking VEDO 273 service notebook (ERC5800).
F3 — open sensor or sensor circuit (ERC5800 service literature). Decode varies by EOC generation.
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.
What this code means
Viking VEDO service literature lists F3 as open sensor or sensor circuit and directs checking sensor resistance and wiring. Viking uses multiple electronic oven control (EOC) generations; the same display can decode differently by model year. Record your model and serial numbers and confirm against your appliance documentation.
Symptoms you may notice
- F3 displayed
- Oven may not heat or regulate temperature
- May appear during preheat
Possible causes
- Open RTD/temperature sensor or harness (service literature)
- Corroded or loose sensor connector
- Failed sensor (requires measurement by a technician)
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
- Allow the oven to cool
- One breaker power cycle only
- Contact an independent Viking technician for sensor resistance testing — do not probe live circuits
Important safety warning. Do not open internal panels, access high-voltage wiring, or bypass any safety device. If you ever smell gas, stop immediately, do not operate any switches, leave the area and contact your gas provider and a qualified technician. If you see smoke, sparks, a burning smell, or water near electrical parts, switch the appliance off at the outlet if it is safe to do so and call a professional.
What not to attempt
- Do not open internal panels or access high-voltage components
- Do not bypass door locks, safety switches or interlocks
- Do not adjust, disconnect or repair any gas connection or valve
When to call a technician
If F3 persists, schedule service. Sensor and wiring diagnosis requires proper tools and safety practice.
