KitchenAid Oven Error Code F3-E2 — Oven Temperature Sensor Short Circuit
What this means
Error code F3-E2 indicates the oven temperature sensor has a short circuit, meaning the resistance reads abnormally low (near zero ohms). This causes the control board to receive incorrect temperature data, which can lead to overheating or no heating. The short can be in the sensor itself or in the wiring between the sensor and the control board.
Alternate codes: F3E2
Step-by-step fix
4 stepsPower cycle the oven
Turn off the circuit breaker for 1 minute, then restore power. Check if the error clears.
A moisture-related temporary short can sometimes clear after the oven cools and dries.
Test the sensor resistance
Unplug the oven and disconnect the sensor wires. Measure resistance across the sensor terminals. A shorted sensor reads near zero ohms instead of the normal 1,080 ohms at room temperature.
Also check for continuity between each sensor wire and ground (oven chassis) — there should be none.
Inspect sensor wiring
Check the sensor wires from the oven cavity to the control board for damaged insulation, pinched wires, or bare conductors touching the oven chassis.
Wires can get damaged by heat cycling or by oven racks being pushed against them.
Replace the temperature sensor
If the sensor reads shorted, replace it. Remove the mounting screws inside the oven, pull the old sensor out, and install the new one.
Route the new sensor wire carefully away from the oven walls to prevent future damage from heat.
When to call a professional
If the sensor tests good but the error persists, there may be a wiring short between the sensor and the control board that requires tracing through the oven cavity.
