Frigidaire Microwave Error Code SENSOR ERROR

SENSOR ERROR on a Frigidaire microwave means the humidity sensor did not detect steam from the food during a sensor cooking cycle, or the door was opened before steam was sensed. The microwave uses this sensor to determine how long to cook food automatically. If detection fails or is interrupted, the unit displays this error and stops the cycle. You can continue cooking by using the manual Cook Time setting instead.

Unplugging the microwave for a minute and plugging it back in will clear the displayed error code, but it will not fix the underlying cause. If the problem is user behavior such as opening the door too early, adjusting that habit will prevent the error from returning. If the sensor or control board is faulty, the error will reappear and a reset alone will not resolve it.

If the fix is simply a behavior adjustment or interior cleaning, there is no parts cost involved. If the humidity sensor needs replacement, parts and labor costs typically range from around 75 to 200 dollars depending on the model and service rates in your area. A control board replacement, if required, generally runs higher, often between 150 and 350 dollars including labor.

First, make sure you are not opening the door during the sensor detection phase. Allow the microwave to run uninterrupted until the countdown timer appears on the display. If the error persists, try cooking a larger food portion or switch to manual Cook Time mode. If the error occurs consistently, inspect the interior cavity for grease buildup near the sensor and clean it thoroughly.

Yes, the SENSOR ERROR does not indicate a safety hazard. It simply means the automatic sensor cooking feature could not complete its detection cycle. You can safely continue using the microwave by cooking with manual time and power settings rather than sensor cooking modes.
