Dacor Cooktop F2 Error: Temperature sensor fault
Dacor cooktop error code f2 — essential information for Dacor appliance owners. This dacor cooktop f2 error code guide explains what this fault means for your Dacor appliance and how to respond safely. The F2 error code on a Dacor induction cooktop points to a temperature sensor (thermistor) failure. The DTI30 and DTI36 rely on […]

Answer to continue safely
Is it safe to keep using?
No. A failed temperature sensor means the cooktop cannot regulate heat safely. Operating the unit risks overheating the glass and surrounding cabinetry. Do not use until the thermistor is replaced.
Can I reset the code?
Yes. Breaker reset clears F2 from the display, but the sensor fault remains. The code will return as soon as the affected zone is used. Reset alone is not a fix.
When to stop immediately?
Stop if you notice: Stop use immediately if the glass surface is cracked or chipped anywhere near the zone center., Do not use the faulty zone if F2 returns every time that specific zone is activated..
Symptoms You May Notice
Cooking zone shuts off without warning
One or more induction zones stop heating mid-use and the display shows F2. Other zones may continue working if only one sensor has failed.
F2 displayed on the cooktop screen
The DTI30 or DTI36 display shows F2, sometimes flashing, and an alert tone sounds to draw attention to the fault.
Cooktop runs briefly then shuts down
The surface heats for 30–90 seconds then cuts out. This pattern suggests the sensor is reading intermittently rather than being completely open-circuit.
Surface feels unusually hot before shutdown
Because the sensor cannot properly report temperature, the coil may briefly over-drive before the safety limit triggers the F2 shutdown.
Possible Causes
Failed or disconnected thermistor
The NTC thermistor bonded to the glass-ceramic beneath each cooking zone has failed open or short, or its connector has worked loose from vibration.
Requires ProfessionalDamaged sensor wiring harness
The thin wire leads running from the sensor to the control board can be pinched, burned, or corroded, producing an open or out-of-range resistance reading.
DIY PossibleCracked or chipped glass-ceramic surface
Physical damage to the cooktop surface can dislodge or break the thermistor that is bonded directly beneath the glass.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle and test each zone individually
Reset the cooktop at the breaker. Test each induction zone one at a time using a compatible induction-ready pot. Note which zone triggers F2 — if only one zone faults, that zone's thermistor is the likely culprit.
Use a small 6-inch pot on each zone sequentially at medium power and observe for 2 minutes.
-
2
Inspect the glass surface for cracks
With the cooktop cool and powered off, examine the glass-ceramic surface closely under good lighting for hairline cracks, chips near zone centers, or discoloration that could indicate a damaged thermistor beneath.
Run a fingertip lightly across zone centers — even a hairline crack can be felt.

3
Check sensor wiring (technician level)
A technician can remove the base panel, locate the thermistor leads for the faulting zone, and test resistance with a multimeter. A healthy NTC thermistor reads approximately 10 kΩ at room temperature; an open or shorted reading confirms sensor failure.
Dacor service documentation specifies the exact resistance range for each thermistor model.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Thermistor resistance is out of spec — sensor replacement requires accessing the underside of the glass-ceramic assembly.
- Glass-ceramic surface damage requires full surface panel replacement by a certified Dacor technician.
- F2 appears on multiple zones simultaneously, suggesting a wiring harness or board issue beyond a single sensor.
