JennAir Built-In Message ERROR during sensor cooking: humidity not detected

What ERROR during sensor cooking means

On JennAir built-in microwaves, microwave drawers and the microwave section of combination wall ovens, such as the JMC2430LL or JMC2430DS, ERROR during sensor cooking means the sensor is not detecting humidity. The microwave could not get a steam reading from the food. Check the food and the cover, then start the program again. This is usually about how the food was prepared, not a failed part.

Common causes of ERROR during sensor cooking

Food is too dry or too small to give off steam
Cover is too tight or too loose
Sensor program was used with the wrong food type
Humidity sensor needs service if the message repeats

✓ One safe check you can try

1. Open the door and look at the food and its cover. 2. Use a loose cover or vented wrap, and avoid foil or tight lids. 3. Wipe the cavity and door seal. 4. Restart the sensor program once. 5. If ERROR returns with suitable food, cook manually and call us.

! Why to stop there

Most cases come from food and cover, which we cannot fix by service.
If the message repeats with proper food, the sensor must be tested.
Opening a built-in unit calls for care around live parts.
If we come out, our price is written first and the work has a 30-day warranty.

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.

ERROR during sensor cookingERROR during sensor cooking questions

What should I do first when ERROR appears?

Check the food and cover as the message says. Make sure steam can escape slightly and the food is suitable for sensor cooking, then start the program again.

Does ERROR during sensor cooking mean the sensor is broken?

Not necessarily. Dry food or a tight cover keeps steam from reaching the sensor. If good conditions still produce the message, then we test the sensor and its wiring.

Can I finish the dish another way?

Yes. Use time and power manually, stir the food partway through, and check its temperature before eating, since the sensor is not guiding the cook.
