KitchenAid Oven Error Code F3-E0

F3-E0 means the control board detected an open circuit in the oven temperature sensor. The sensor, also called an RTD probe, should measure around 1080 ohms at room temperature. An open circuit means the board is reading no resistance at all, typically caused by a failed sensor, a loose connector, or a broken wire in the harness.

No. With F3-E0 active, the control board has no reliable temperature data and cannot regulate oven heat. Operating the oven in this state risks overheating the cavity with no automatic cutoff based on temperature feedback. Do not use the oven until the sensor circuit fault is resolved.

Yes. Disconnect the oven from power, pull the sensor out from inside the oven cavity (usually two screws), and disconnect the harness plug. Set a multimeter to the ohms setting and measure resistance across the two sensor terminals. At room temperature near 70°F, a good sensor reads close to 1080 ohms. If your reading is OL, infinite, or far outside this range, the sensor has failed and should be replaced. If the reading is in range, the problem is likely in the wiring or at the control board.

Start by unplugging the oven and checking the sensor connector at both the probe and the control board for looseness or corrosion. Then use a multimeter to measure resistance at the sensor terminals: a healthy sensor reads approximately 1080 ohms at 70°F, increasing by about 2 ohms per degree. If you read OL or infinite resistance, replace the temperature sensor. If the sensor reads correctly and connections are secure, the control board may have a welded relay and will need professional evaluation or replacement.

A replacement oven temperature sensor typically costs $20 to $60 in parts and takes about 15 to 30 minutes to swap out, making it a manageable DIY repair. If the wiring harness is damaged, harness repair or replacement adds parts cost and complexity. A control board replacement, needed only if the sensor and wiring are both confirmed good, generally runs $150 to $350 in parts alone, plus labor if professionally installed.
