Whirlpool Microwave Sensor Error — What It Means & How to Fix It
Also shown as ERROR, Error during sensor cooking on some models.
ERROR during sensor cooking means the sensor is not detecting humidity from the food — check the food and how it is covered, then start the program again.
What this code means
Whirlpool says the sensor is not detecting humidity: check the food and the cover, then start the program again, and refer to Sensor Cooking in the owner's manual. Sensor programs rely on steam escaping from the food to judge progress.
From Whirlpool's built-in microwave help; applies to sensor cooking programs only.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Food sealed too tightly, so no steam escapes | Common | Yes — vent the cover |
| Very small or dry portion | Common | Yes — use timed cooking |
| Door opened during the sensing period | Common | Yes — keep it closed |
| Humidity sensor fault | Occasional | No — technician job |
What you can try yourself
- Check the dish is covered as your manual recommends for sensor cooking — loosely, so steam can escape.
- Make sure there is enough food, and that it is not completely dry.
- Start the sensor program again and leave the door closed.
- If it fails again, use a timed cook and have the sensor checked.
When to call a technician
- ERROR on every sensor program with suitable food.
- A humidity sensor code also appears.
- Sensor cycles never end and food overcooks.
Typical professional repair cost: Free in most cases; a humidity sensor replacement costs about $120–$250.
