Viking Wall Oven F-Code Guide — F1, F2, F3, F4, F9 Explained

Viking wall ovens use the same Electronic Range Control (ERC) as Viking ranges. Specifically, as a result, f-series fault codes are identical across both product types. F1 is a control board fault, F2 a temperature sensor short, F3 an open sensor circuit, F4 temperature runaway. Additionally, f9 a self-clean door lock failure.

Furthermore, reset any F-code by switching off the circuit breaker for 60 seconds. Additionally, if the code returns, professional repair requires action.

In addition, if any step seems unsafe or unclear, stop and call a certified technician. As a result, you protect both yourself and your appliance from further damage.

Step-by-Step Instructions

First, read all the steps before you begin. After that, gather the tools you need and follow the process in order:

  1. F1 — Control Board Failure — F1 indicates the ERC has detected an internal fault. Specifically, reset by switching off the circuit breaker for 60 seconds. If F1 returns, the control board requires professional replacement.
  2. F2 — Temperature Sensor Short Circuit — F2 means the oven temperature sensor probe is reading a short circuit. Specifically, do not use the oven with F2 active. A technician replaces the probe with a genuine Viking OEM part.
  3. F3 — Temperature Sensor Open Circuit — F3 means the temperature sensor circuit is open. Specifically, the technician checks the connector and wiring harness before replacing the sensor probe.
  4. F4 — Temperature Runaway — F4 triggers when the oven exceeds the set temperature by more than 50 degrees F. Specifically, this safety fault requires professional repair before the oven technicians use again.
  5. F9 — Self-Clean Door Lock Failure — F9 indicates the self-clean door lock did not engage or disengage. Specifically, switch off the circuit breaker for 5 minutes to reset the lock motor. If the door remains locked, professional service requires action.

However, if the fault persists after you complete these steps, contact our team. In that case, the appliance likely needs professional repair with replacement parts.
