Jenn-Air Oven Error Code F1E7-2

F1E7-2 indicates that the microwave Appliance Control Unit has detected an over-temperature condition caused by a shorted temperature sensor. The sensor circuit is reading abnormally low resistance, which the control board interprets as a fault. The microwave function will be disabled until the issue is diagnosed and corrected.

The oven's microwave function should be considered out of service when this code is active, as the control system has detected a sensor fault and disabled that function as a protective measure. Standard bake and broil functions may still operate depending on the model, but continuing to use the appliance without addressing the fault is not recommended. Disconnect power and have the unit inspected before resuming normal use.

Repair costs vary depending on the root cause. If the issue is only a loose connector, there may be no parts cost beyond a service call fee, which typically ranges from $75 to $150. Replacing a shorted thermistor sensor generally adds $20 to $80 in parts. If the ACU main control board has failed, parts alone can range from $150 to $400 or more, plus labor.

Some homeowners with electrical knowledge can handle the initial steps, such as unplugging the unit and inspecting wiring connectors for loose or unseated connections. If the fault involves a shorted thermistor or damaged wiring harness, those repairs require component testing and part replacement, which are better suited to a trained technician. Working inside the oven cavity and near the control board requires full power disconnection before any inspection.

Unplugging the range or cycling the breaker may temporarily clear the fault display, but the code will return if the underlying sensor short is still present. A reset does not repair a shorted thermistor or damaged wiring. The root cause must be identified and corrected for the fault to stay cleared.
