Monogram Cooktop E1 Error: Induction temp sensor fault
The induction zone temperature sensor has detected a reading outside the safe operating range, causing the cooktop to suspend power to that zone to prevent overheating or component damage.

Answer to continue safely
Is it safe to keep using?
No. A high-severity temperature sensor fault means the cooktop cannot guarantee safe thermal cutoff on the affected zone. Do not use the faulty zone until the fault is diagnosed and resolved.
Can I reset the code?
Yes. A power-cycle reset via the circuit breaker can clear a transient E1 fault. If the code returns immediately or after a short period of use, a hardware repair is required.
When to stop immediately?
Stop if you notice: The error returns within minutes of resetting the power., You notice any burning smell or discoloration around the cooktop surface..
Symptoms You May Notice
Induction zone stops heating mid-cook
The affected induction zone cuts power suddenly during cooking, leaving food partially heated with no warning other than the error display.
E1 code shown on touch display
The alphanumeric display on the cooktop surface shows the E1 code, typically accompanied by a series of audible beeps.
Zone indicator light flashes rapidly
The indicator ring or LED around the affected induction zone flashes repeatedly, signaling an active fault condition.
Cooktop locks further zone selection
Attempting to activate another cooking zone may be blocked or limited while the E1 fault remains active on the affected zone.
Possible Causes
Faulty NTC temperature sensor
The negative temperature coefficient sensor mounted beneath the induction coil has drifted out of calibration or failed, sending incorrect resistance readings to the control board.
Requires ProfessionalRestricted airflow causing overtemperature
Blocked ventilation slots or a failed cooling fan causes the coil area to overheat, tripping the thermal protection sensor before a true component failure occurs.
DIY PossibleControl board sensor input circuit fault
Corrosion or a loose connector on the main control board sensor input can produce erratic voltage readings that the firmware interprets as an out-of-range temperature.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the cooktop
Turn the cooktop off at the control panel, then switch off the dedicated circuit breaker for 60 seconds. Restore power and attempt normal operation. A transient sensor glitch will often clear with a full power reset.
Wait the full 60 seconds — a shorter reset may not discharge the control board capacitors completely.
-
2
Check ventilation slots for blockage
Inspect the underside grille and any accessible ventilation openings around the cooktop perimeter. Remove cooking debris, foil, or objects that may be obstructing airflow into the cooling fan intake.
Use a flashlight to inspect the slots from below the countertop cutout if the cooktop is drop-in mounted.

3
Verify cookware compatibility
Confirm that the pot or pan used on the zone is ferromagnetic and the correct size for that zone. Incompatible cookware can cause the zone to cycle erratically and may trigger thermal faults.
Hold a magnet to the base of your cookware — if it sticks firmly, the cookware is compatible.
When to Call a Professional
Contact a qualified technician if:
- The E1 code persists after two consecutive power-cycle resets separated by 10 minutes.
- The cooling fan is audibly not running when the cooktop is powered on.
- The NTC sensor reads open or short circuit when tested with a multimeter.
