Maytag Range Error Code F3

F3 means the control board has detected an open or shorted circuit in the oven temperature sensor loop. The sensor, also called an RTD probe, monitors oven cavity temperature. When the board reads a resistance value that is either too high (open) or too low (shorted), it disables the oven and displays F3. The surface burners are not part of this circuit and may still work.

You should not use the oven while F3 is active. The control board has disabled oven heating because it cannot monitor temperature, which means the oven could overheat without the board knowing. Surface burners on gas or electric models are typically on a separate circuit and may still be safe to use, but confirm the oven is completely non-functional before using the range for any cooking.

Yes, replacing the oven temperature sensor is one of the more accessible range repairs. The sensor is mounted inside the oven cavity with one or two screws and connects via a wiring harness through the rear wall. After unplugging the range, remove the screws, pull the sensor forward, disconnect the harness, and install the new sensor in reverse order. Confirm the replacement sensor is the correct part number for your specific Maytag model before ordering.

Start by unplugging the range and locating the oven temperature sensor at the rear wall inside the oven cavity. Disconnect the sensor and measure its resistance with a multimeter. A working sensor reads approximately 1080 to 1100 ohms at room temperature. If the reading is open (OL) or near zero, replace the sensor. If the sensor measures correctly, inspect the wiring harness and connectors between the sensor and the control board for damage, pinching, or corrosion and repair as needed.

An oven temperature sensor is the most common fix and typically costs between $20 and $60 for the part. The replacement is a beginner-level repair requiring only a screwdriver, so many homeowners do it themselves. If the wiring or control board is the cause, parts costs range from under $20 for a connector repair to $150 or more for a control board. Adding a professional technician's labor, expect a total service call to run $100 to $300 depending on which component needs replacement.
