Kenmore Range F2 Error: Oven Over-Temperature (Legacy — Pre-2005 Models)
The kenmore range f2 error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Range Error Code F2 Mean? F2 on an older Kenmore 790-series electric range — models from approximately 2005 or earlier that use single-digit F codes […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. F2 on a legacy Kenmore range indicates either a genuine over-temperature condition or a sensor failure that mimics one. In either case, the oven must not be used until the RTD sensor and EOC board are diagnosed. A stuck relay situation is a fire risk.
Can I reset the code?
Yes. Pressing Cancel and performing a 5-minute breaker reset clears F2 from the display. If the underlying cause is a shorted sensor or stuck relay, F2 will return on the next cook cycle and the oven must not be used until repaired.
When to stop immediately?
Stop if you notice: F2 occurs during preheat before the oven reaches the selected temperature — indicating a shorted sensor, Smoke or burning smell from the oven preceded the F2 alert.
Symptoms You May Notice
Oven shuts off mid-cycle with F2 displayed and an alarm sounding
A bake or self-clean cycle terminates abruptly. The display shows F2 and an alarm sounds. The EOC board has cut power to all heating elements. Pressing Cancel clears the alarm and display.
Oven runs noticeably hotter than the temperature selected before F2 appears
Food is over-browned or there is smoke from the oven before F2 triggers — indicating the actual cavity temperature exceeded the set point significantly before the safety cutout intervened.
F2 appears during self-clean above 990°F — a different threshold than normal cook mode
During self-clean cycles, the temperature threshold for F2 on older Kenmore 790-series models is higher (typically 990°F). F2 during self-clean often indicates a stuck relay running the element continuously through the high-temp phase.
Oven cavity smells scorched after F2 shutdown
A sharp burnt odor lingers in the kitchen after the oven cuts out. Pans inside may show charred food residue or deep browning on the tops, consistent with cavity temperatures well above the selected setting.
Possible Causes
Shorted oven RTD temperature sensor
The RTD probe has shorted internally, causing it to read near-zero resistance — which the EOC board interprets as a very high temperature. The board may trigger F2 during preheat before any real over-temperature condition exists.
DIY PossibleStuck-closed bake or broil element relay on the EOC board
A relay on the EOC board has welded contacts, keeping the heating element energized continuously. The oven genuinely overheats, and the RTD sensor correctly reports the high temperature that triggers F2.
Requires ProfessionalEOC board calibration offset error after a power event
A corrupted calibration value in the board EEPROM causes the board to systematically interpret the sensor reading as hotter than actual, triggering F2 at normal cooking temperatures.

Test oven RTD sensor resistance after the oven cools
Allow the oven to cool completely. Turn off the range at the circuit breaker. Locate the RTD sensor in the upper rear of the oven cavity, disconnect its wiring connector, and measure resistance with a multimeter. The correct reading at room temperature (68°F / 20°C) is approximately 1,080–1,100 ohms. A reading near zero ohms confirms a shorted sensor — replace it before any further operation.
A sensor that tests within range at room temperature but that was the cause of F2 during a high-temperature self-clean may have failed at high temperature. A technician can test the sensor at elevated temperatures to confirm drift behavior that is not apparent at room temperature.

Perform a 5-minute breaker reset and monitor preheat carefully
If the RTD sensor tests within spec, switch off the circuit breaker for 5 minutes to reset the EOC board. Place an independent oven thermometer on the center rack. Restore power and preheat to 350°F, observing both the oven display temperature and the independent thermometer. A large divergence (displayed temperature 50°F or more above thermometer) points to a sensor issue. Matching temperatures that both climb past 500°F without slowing points to a stuck relay — disconnect power immediately at the breaker.
Never leave the kitchen during this monitoring test on a range that has previously triggered F2. A stuck relay can drive the oven to dangerous temperatures within minutes of power being restored.

When to Call a Professional
Contact a qualified technician if:
- RTD sensor resistance is near zero ohms at room temperature — confirming a shorted sensor
- F2 returns after sensor replacement — indicating a stuck relay on the EOC board
- Oven reached confirmed temperatures above 650°F during a normal bake cycle before F2 triggered — indicating a stuck relay requiring board replacement before further use
