Whirlpool Built-In Microwave “ERROR” in Sensor Cooking: Humidity Not Detected

Low risk · DIY check OK

Code: ERROR during sensor cooking
Appliance: Microwave
Brand: Whirlpool
Warranty: 30-day workmanship

What ERROR during sensor cooking means

If ERROR appears while using sensor cooking on a Whirlpool built-in microwave or microwave drawer, such as model WMC50522AS, the sensor is not detecting humidity from the food. This usually happens when the food is not covered properly, the container is wrong, or the amount of food gives off too little steam. It is more often a cooking setup than a failed part. The microwave stops the program and you need to restart it.

Common causes of ERROR during sensor cooking

Food not producing enough steam or not covered properly
Sensor program used with the wrong food or container
Humidity sensor reading
Temporary control glitch

✓ One safe check you can try

1. Check the food and its cover, then start the program again. 2. Read the Sensor Cooking section in your owner's manual for your model. 3. If the message returns, turn the breaker off for one minute and on again. 4. Watch the oven for one minute. 5. Try a timed cycle to check that heating works.

! Why to stop there

If the message appears with different foods that follow the manual, we test the humidity sensor and its circuit.
Timed cooking that works while sensor cooking does not points us to the sensor path.
You get a written price before 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.
