Maytag Oven Error Code F1E7

The F1E7 error code on a Maytag oven indicates that the PCB thermistor on the main control board has either gone open circuit or shorted out. This onboard thermistor monitors the temperature of the control board itself, not the oven cavity. When the sensor reads a temperature above 150°C or below -10°C, the control interprets the reading as a fault condition and locks up entirely to protect the electronics from potential damage. The result is a non-functional control panel and an oven that will not operate.

The PCB thermistor is a passive temperature-sensing component integrated into the main control board. Unlike the oven temperature sensor probe that hangs inside the cavity, this thermistor is soldered directly onto the control board's printed circuit. An open circuit condition means the thermistor or its connection has broken and no longer conducts, producing a reading that falls below the -10°C threshold. A shorted condition means the sensor is reading an artificially elevated temperature above 150°C, which can occur from a failed thermistor component or internal board damage.

Because the thermistor is soldered onto the control board and not a separately serviceable component, the diagnostic path leads directly to replacing the main control board. There is no field repair for an onboard sensor failure of this type. Heat damage, power surges, moisture intrusion, or simple component aging are the most common underlying causes of PCB thermistor failure. Once the board locks up due to F1E7, a power reset alone will typically not resolve the issue if the thermistor itself has failed.
