Maytag Oven F3 Error Code: Open Oven Temperature Sensor
Quick Answer
Maytag F3 indicates the oven temperature sensor has an open circuit - the resistance reading is infinite, meaning the wire is broken or the sensor element has failed. Maytag ovens use the same RTD spec as Whirlpool: approximately 1,080 ohms at room temperature. The sensor is a thin probe mounted inside the rear wall of the oven cavity.

Maytag ovens use the same RTD spec as Whirlpool: approximately 1,080 ohms at room temperature. The sensor is a thin probe mounted inside the rear wall of the oven cavity. Measure its resistance at the control board connector: should read 1,080 ohms at room temp, rising to ~1,820 ohms at 350F. If it reads OL (open), replace the sensor ($15-30).
