What ERROR during sensor cooking means

On KitchenAid built-in microwaves and combination ovens, for example the KMBP100ESS or KOCE500ESS, "ERROR" during a sensor cooking program means the sensor is not detecting humidity. The oven expects steam from the food to rise and register. When it does not, the program stops with the message. Usually the cause is the food, the cover or how the cycle was started, not a failure.

Common causes of ERROR during sensor cooking

  • Food covered too tightly, or not covered when it should be
  • Cooking started when the cavity was already warm or damp
  • A very small, dry or already hot portion that produces little steam
  • A humidity sensor that needs a power reset
✓ One safe check you can try

1. Open the door and check the food and cover, as the instructions for sensor cooking describe. 2. Wipe moisture from the cavity and dry the door seal. 3. Restart the sensor program with a fresh portion at normal starting temperature. 4. If the message remains, reset the breaker for one minute and watch the display for another minute before cooking again.

! Why to stop there
  • Food and cover are the usual reason, and you can test those at no cost
  • A true sensor problem has to be confirmed with measurements before a part is ordered
  • We quote first and give a 30-day workmanship warranty on any repair
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
Why does sensor cooking end with ERROR?

The oven waits for humidity from the food, and it did not see any. Food that was dry, too small or cooked after a previous cycle can produce too little steam.

Should I use time cooking instead?

Yes, that is a good workaround. Time-based cooking does not depend on the humidity sensor, so you can keep using the oven while you investigate.

When does ERROR point to a bad sensor?

If it appears on every sensor program with different foods, a clean and dry cavity, and after a power reset, the sensor or its wiring needs a technician's test.

Still unsure about ERROR during sensor cooking?

A technician diagnoses it on site and gives you the price in writing before any work starts.
