Kenmore Oven F2 Error Code - Causes & Fix

What this code means

The F2 code on a Kenmore oven is model-specific and carries different meanings depending on your exact control platform. On many Kenmore ranges it signals an overtemperature condition (oven running too hot), while on other models it indicates a temperature sensor or probe fault, or a communication problem between the sensor and the electronic oven control. Some Kenmore units displaying E0 F2 use this code to flag a stuck or shorted keypad membrane. Because Kenmore is a brand label applied to appliances built by multiple manufacturers, you must confirm the exact code definition in your model’s tech sheet or wiring diagram before ordering parts.

In practice, technicians find F2 most often when the oven temperature sensor has failed, when the sensor harness has a loose or corroded pin, or when the electronic control board’s bake or broil relay has welded shut and allowed runaway heat. On ranges recently run through a self-clean cycle, residue or debris can sometimes trigger a false overheat alarm. The fault typically locks out normal oven operation until the underlying cause is corrected and power is reset.

Before You Replace Anything

Many owners replace the electronic oven control board first when the actual problem is a failed temperature sensor or a loose harness connection. Always measure sensor resistance and inspect the wiring harness before ordering a new control.

Common Causes

• Failed oven temperature sensor or probe The sensor reads out of range, open, or shorted and the control interprets the signal as a fault or overheat condition.
• Loose, dirty, or corroded sensor harness connections Pins at the sensor or control board are oxidized, pushed back, or not fully seated, breaking the signal path.
• Damaged wiring harness between sensor and control Insulation melted by heat, wires pinched during installation, or rodent damage creates an open or short circuit.
• Welded bake or broil relay on the electronic oven control Relay contacts stick closed, allowing continuous power to the heating element and causing genuine overtemperature or a false alarm.
• Shorted or stuck keypad membrane (E0 F2 variant) A button is physically stuck or the membrane switch matrix has shorted, confusing the control into setting a fault code.
• Defective electronic oven control board If the sensor, wiring, and relays all check good, the control itself has failed and misreads normal signals as a fault.

Step-by-Step Fix

1. Power down the range at the circuit breaker and verify zero voltage at the terminal block before opening any panels or touching internal wiring.
2. Locate your model and serial number on the rating plate (usually inside the oven door frame or on the chassis) and download the tech sheet or wiring diagram to confirm the exact F2 code definition for your control platform.
3. Inspect the oven temperature sensor and harness. Remove the sensor probe (typically one or two screws at the rear wall) and examine the probe tip, wiring insulation, and connector pins for heat damage, corrosion, or breaks.
4. Measure sensor resistance at room temperature using a digital multimeter. Compare the reading to the specification in your tech sheet. If the sensor reads open, shorted, or far outside the expected range, replace it.
5. Check harness continuity from the sensor connector to the control board. Wiggle wires while measuring resistance to reveal intermittent breaks. Repair or replace damaged harness sections.
6. Inspect the electronic oven control for welded relays if the oven has been overheating or if the code appears immediately after a self-clean cycle. Look for burn marks, melted plastic, or relay contacts that do not spring open.
7. Reset power at the breaker, run a short bake test at a moderate temperature (for example 350 degrees), and monitor whether the F2 code returns. If the fault is gone, the repair is complete.
8. Replace the electronic oven control if the sensor, wiring, and relays all test good but the code persists. The control board’s internal circuits have likely failed.

Parts Often Needed

When to Call a Pro

Call a professional if you are not comfortable working inside a live 240-volt appliance, if you cannot locate or access the temperature sensor, or if the oven continues to overheat after you have replaced the sensor. Welded relay contacts and control board replacement require careful handling of high-voltage connections and often benefit from a technician’s multimeter and relay-test tools. If your range has recently completed a self-clean cycle and the oven cavity is still too hot to touch hours later, shut off the breaker immediately and call for service to prevent fire or further damage. A qualified appliance technician will carry model-specific tech sheets, relay testers, and replacement boards to complete the repair in one visit.
