JennAir JMV Code F8E5: exhaust air temperature sensor

What F8E5 means

F8E5 is displayed by JennAir over-the-range microwave hoods like the JMV9196CS and JMV8000 series when the oven could not execute the function and the exhaust air temperature sensor or its wiring may be the cause. This sensor watches the temperature of air leaving the unit. With F8E5, the microwave may stop mid-cycle or refuse to run. Built-in JennAir units name an exhaust fan air sensor.

Common causes of F8E5

Exhaust air temperature sensor has failed
Wire or connector to the sensor is loose
Hot, greasy air has damaged the sensor lead

✓ One safe check you can try

1. Press Stop/Cancel and open the door to cool. 2. Check the exhaust openings for blockage or heavy grease. 3. Make sure nothing sits on top of the hood. 4. Do a one-minute power reset at the breaker. 5. Try a short run with water, and call us if F8E5 repeats.

! Why to stop there

The sensor sits in the exhaust path inside the housing.
A wrong air reading can hide a true overheat.
Telling a sensor failure from an airflow problem needs measurements.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F8E5F8E5 questions

Can blocked airflow trigger F8E5?

It can raise exhaust temperatures, but the code names the sensor circuit. Clearing the opening is worth doing, and if F8E5 stays, the sensor itself gets tested.

What does the sensor protect?

It lets the control confirm that air is leaving the unit at a safe temperature. Without a reading, the control chooses to stop the function.

How soon should I call?

If microwaving still works, you have a little time, but use it sparingly. If the unit shuts off constantly, call us now so the sensor does not cause more wear.
