Viking Range F01 Error: Runaway oven temperature
What Does the Range Error Code F01 Mean? The F01 error code on a Viking range indicates a runaway oven temperature condition. The oven has exceeded the user-set temperature by a significant margin, typically due to a stuck relay on the control board or a failed oven temperature sensor (RTD). This is a serious fault […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A runaway temperature condition poses a fire and safety hazard. Do not use the oven until the fault is diagnosed and repaired.
Can I reset the code?
Yes. Power cycling the breaker for 5 minutes may temporarily clear the error, but the underlying fault will likely return. A reset is not a repair.
When to stop immediately?
Stop if you notice: The oven interior exceeds 600°F or you smell burning plastic or wiring., The error returns immediately after a power cycle reset..
Symptoms You May Notice
Oven overheating
The oven interior becomes far hotter than the temperature you set, sometimes reaching unsafe levels.
Error code on display
F01 flashes or remains lit on the control panel display, often accompanied by a beeping alert.
Oven shuts off unexpectedly
The control board may cut power to the heating elements as a safety measure, causing the oven to stop mid-cook.
Burning smell
Excessive heat can cause food or oven liners to scorch, producing a noticeable burning odor.
Possible Causes
Stuck relay on control board
A relay on the electronic control board may be welded shut, continuously supplying power to the bake or broil element even when it should be off.
Requires ProfessionalFailed oven temperature sensor (RTD)
The resistance temperature detector (RTD probe) may be sending incorrect readings to the board, causing it to believe more heat is needed.
DIY PossibleFaulty electronic control board
Internal board circuitry damage can cause incorrect temperature regulation logic, triggering the runaway condition.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the range
Turn off the circuit breaker supplying power to the range and leave it off for at least 5 minutes. This allows the control board capacitors to fully discharge. Restore power and see if the error clears.
If the error returns within the first cook cycle, the fault is persistent and hardware-based.

2
Inspect the oven temperature sensor
With the oven fully cool and power disconnected, locate the RTD probe inside the oven cavity (usually at the back wall). Check for visible damage, corrosion, or a loose connector. Use a multimeter to measure resistance — a good Viking RTD reads approximately 1,080–1,100 ohms at room temperature.
A reading far outside 1,000–1,200 ohms at room temperature indicates a faulty sensor.

3
Check element and wiring visually
With power disconnected, visually inspect the bake and broil elements for any signs of arcing, burn marks, or holes. Also check the wiring harness leading to the control board for melted insulation.
Do not operate the oven if you find a visibly damaged element.
When to Call a Professional
Contact a qualified technician if:
- Control board relay replacement — requires soldering or full board swap.
- RTD sensor replacement if wiring harness is damaged.
- Any repair involving the high-voltage bake or broil element wiring.
