Amana Range Error Code F1-3

The F1-3 error code on an Amana range indicates an over-temperature condition detected during the self-clean cycle. During self-cleaning, the oven cavity reaches temperatures between 800 and 1000 degrees Fahrenheit to incinerate food residue. The control board continuously monitors the oven temperature sensor (RTD probe) throughout this process. If the sensor reports temperatures exceeding the programmed upper threshold, or if the sensor signal falls outside the expected resistance range, the control interprets this as a dangerous over-temperature event and terminates the clean cycle, displaying F1-3.

The primary components involved are the oven temperature sensor and the electronic control board. The temperature sensor is a resistive device whose resistance changes predictably with temperature. At room temperature, a properly functioning sensor typically reads around 1080 to 1100 ohms. A sensor that has failed open, failed short, or drifted out of calibration will send incorrect temperature data to the control board, which can trigger this fault even when the oven has not actually exceeded safe operating limits. Wiring harness issues between the sensor and control board, such as chafed insulation or loose connectors, can cause similar erratic readings.

Diagnosis should begin with the temperature sensor and its associated wiring. Disconnect the sensor and measure its resistance with a multimeter. If the resistance value is within specification, inspect the wiring harness for damage, corrosion, or loose terminals. If both the sensor and wiring check out correctly, the electronic control board itself is the likely source of the fault and should be replaced.
