Error codeErr / SENSOR ERROR
ApplianceAdvantium Oven
Err on the display, SENSOR ERROR scrolling
After a sensor cooking program the display of a ZEM115 reads Err and the words SENSOR ERROR move across it. The Troubleshooting page of the owner’s manual covers this.
Two ways to trigger it
The door was opened, or Start/Pause pressed, before steam was detected during a Sensor Cooking program.
No steam was detected within the maximum time.
Clearing it
The message scrolls until CLEAR/OFF is pressed. When steam was not detected in time, the manual suggests COOKTIME to heat the food a bit longer.
Model
ZEM115, a countertop microwave from an earlier Monogram range.

LOCKED shows an L and also goes away with CLEAR/OFF.

If SENSOR ERROR returns even after CLEAR/OFF and a timed heat, call (415) 318-7427 in San Francisco or the Bay Area. Name the program you used and the model number. Monogram microwave repair has additional information.
Model compatibility: Monogram reuses codes across series and model years, so Err / SENSOR ERROR may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Err with a scrolling SENSOR ERROR means the door opened or Start/Pause was pressed before steam was detected, or steam was not detected in the maximum time.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
