Kenmore Oven F3/E0 error code
The oven's temperature sensor circuit is open — the electronic control is not receiving any signal from the sensor at all. Without temperature feedback the control cannot regulate heat, so it locks out the oven and displays F3/E0. This is common on Kenmore 665 model ranges.
Also shown as: F3 E0, F3-E0

What causes the F3/E0 error?
- Oven temperature sensor probe burned out
- Loose or corroded sensor wire connection
- Damaged wire harness behind the oven
- Failing electronic oven control board
How to fix Kenmore F3/E0 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Reset the range
Cut power at the breaker for a couple of minutes, then restore it and try the oven. A one-time electronic glitch sometimes clears this way. - Reseat the sensor connection
With power off, locate the slim metal probe sticking out of the upper rear wall of the oven cavity, pull it forward, and reseat its wire connector. Also check the wiring where it passes through the back panel.Safety warning: Always disconnect power at the breaker before touching wiring — the range carries 240 volts. - Test or replace the sensor
Measure the sensor's resistance with a meter — it should read about 1,080 ohms at room temperature (70°F). If it is way off or reads open, replace the sensor. If the sensor tests fine, the electronic oven control is the remaining suspect.Safety warning: If you smell gas at any point on a gas range, leave the house and call your gas company — do not continue troubleshooting.
When to call a technician
- Sensor resistance is correct but the code remains
- You are not comfortable removing panels or using a meter
Frequently asked questions
Can I still use the cooktop with F3/E0?
Usually yes — the code only locks out the oven. The surface burners or cooktop work independently of the oven temperature sensor.
What is the difference between F3/E0 and F3/E1?
F3/E0 means the sensor circuit is open (no signal); F3/E1 means it is shorted (signal stuck). Both point to the same sensor, just failing in different ways.
