Monogram Microwave Error Code Error

This error indicates that the microwave's humidity sensor failed to detect steam during a sensor cooking program such as Sensor Cook, Sensor Reheat, Sensor Beverage, or Sensor Popcorn. It is triggered either by the door being opened while the sensor word is displayed on the control panel, or by the sensor not detecting any steam within the maximum allowed detection time. The microwave stops the program and displays the error to alert you that the sensor cycle could not complete.

Yes, this error does not indicate a safety hazard. It simply means the sensor cooking cycle could not complete its steam detection phase. You can clear the error and either retry the sensor program or switch to a manual cook setting with a timed cook cycle. The microwave is otherwise fully operational.

If the humidity sensor itself needs replacement, parts typically range from around $20 to $80 depending on availability, and professional labor to diagnose and replace the component can add $75 to $200 or more depending on your location and service provider. In many cases though, the error is caused by user interruption or a dirty sensor and requires no parts or service cost at all.

Press CLEAR/OFF to reset the error, then close the door and restart the sensor program from the beginning. Do not open the door while the sensor word such as AUTO, POP, or RHEAT is shown on the display, as this is the window when the microwave is actively sampling for steam. If the error returns repeatedly with the door kept closed, check that the food has adequate moisture content and that the interior of the cavity is clean around the sensor area.

Pressing CLEAR/OFF will clear the error from the display and allow you to restart. However, if the underlying cause such as a faulty sensor or wiring issue is not addressed, the error will return the next time you use a sensor cooking program. For most users, simply restarting the program without opening the door during the detection phase is enough to resolve it permanently.
