Southbend Commercial Oven Error Code F2: Oven Over Temperature
F2 on a Southbend convection oven means the oven interior exceeded its maximum temperature. Turn the oven off and let it cool. A technician should check the gas valve or the element contactor, and then the temperature controller.
High: the oven exceeded its maximum temperature, which is a safety condition.

What does Southbend error code F2 mean?
The controller watches the cavity temperature and compares it with a safe maximum. If the interior goes above that limit, it shows F2. The manual's steps differ by fuel. On a gas oven, check whether the gas valve is stuck open, since that keeps the burner firing when the controller has asked it to stop. On an electric oven, check whether the element contactor is stuck closed, which keeps the elements powered. If neither is stuck, the manual says to replace the temperature controller. The sequence shows the idea: first rule out a part that keeps heating against the controller's command, and only then blame the controller. An over-temperature condition is a safety matter, and the oven should be left off until the cause is found.
Affected models and control systems
Southbend Marathoner Gold and SilverStar gas convection ovens, programmable and rack-timer models (GB/15PC, SLGB/15SC), and Southbend electric convection ovens EB/10PC, programmable and rack-timer models.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- F2 appears on the control display
- The oven is much hotter than the setting
- Food browns or burns faster than usual
- The oven keeps heating after the controller shuts off
Possible causes
Likely causes — what usually sits behind error code F2 on this control. A technician confirms which one it is before any part is replaced.
- Gas valve stuck open (gas ovens)
- Element contactor stuck closed (electric ovens)
- Bad temperature controller
- A probe that reads low so the controller keeps calling for heat
- A contactor whose contacts welded together after a power surge or a heavy load
Safe checks before calling for service
- Turn the oven off and open the door carefully to let it cool.
- If you smell gas, leave the area and call the gas utility.
- On a gas oven, do not relight it. On an electric oven, switch off the breaker if the elements stay hot.
- Write down the setting, the temperature you measured and the model number, and call us.
How a technician diagnoses error code F2
- Read the code and confirm it is F2 on this model.
- On gas, check whether the gas valve stays open when the controller calls for off.
- On electric, check whether the element contactor stays closed with the controller off.
- Compare the probe reading with a thermometer in the cavity.
- Replace the controller only if the valve or contactor is not the cause.
- A gas valve that stays open is a gas safety matter.
- An element contactor that welds shut involves live high-amperage wiring.
- Telling a stuck valve from a bad controller needs a meter and a gas check.
How error code F2 differs from similar codes
F2 differs from F3 and F4, which report the probe open or shorted, and from F1, F5, F6 and F8, which report a bad controller.

Related Southbend convection oven error codes
Is it safe to keep using the oven?
No. An oven that exceeds its maximum temperature should stay off until it is checked.
Is F2 always the controller?
No. The manual first points to a stuck gas valve or a stuck contactor.
Why does the fuel type matter?
Gas ovens have a gas valve and electric ovens have contactors, so the first checks differ.
