Answer to continue safely
Is it safe to keep using?
No. An F1 fault on a Dacor induction cooktop indicates a control board failure. Using the unit risks uncontrolled power delivery to the induction coils. Do not use until repaired.
Can I reset the code?
Yes. A 60-second breaker reset will clear F1 temporarily. However, if the underlying board fault persists the code will return. A successful reset does not mean the problem is resolved.
When to stop immediately?
Stop if you notice: Stop immediately if you smell burning plastic or electronics near the cooktop., Do not use the cooktop if F1 returns within minutes of every reset — continuous operation risks coil damage..
Symptoms You May Notice
Cooktop shuts off mid-cook
All induction zones de-energize suddenly and the display shows F1. The surface may be warm but cooking stops completely.
F1 appears on the display
The alphanumeric display on the DTI30 or DTI36 shows the F1 fault code, typically accompanied by an audible beep sequence.
Control panel unresponsive
Touch controls do not register input after the fault appears. Pressing any zone button produces no response.
Unit will not restart after power cycle
Cutting power at the breaker and restoring it may clear the code temporarily, but F1 returns within minutes of resuming cooking.
Possible Causes
Failed main control board (PCB)
The primary logic board that manages induction coil switching has developed an internal fault, often from power surge or component aging.
Requires ProfessionalLoose or corroded board connector
Ribbon cables or harness connectors between the control board and the power module can work loose over time, triggering a false F1 fault.
DIY PossibleFirmware corruption
Rare but possible after a power surge — the onboard firmware checksum fails self-test and the board reports an F1 condition.
Requires ProfessionalSafe Checks You Can Do
-
1
Hard reset at the circuit breaker
Turn off the dedicated 240V breaker for the cooktop, wait 60 seconds, then restore power. If F1 does not return within 5 minutes of normal use, a transient voltage spike caused the fault.
If you have a surge protector on a nearby outlet, consider having the cooktop circuit evaluated for power quality.

2
Inspect visible wiring connections (service panel only)
If you are comfortable with appliance disassembly, remove the cooktop base panel and visually inspect ribbon cables and harness connectors on the control board for signs of looseness, scorch, or corrosion. Reseat any suspect connectors firmly.
Always disconnect power at the breaker before opening the unit.

Document the fault frequency
Note how often F1 appears and what cooking zone or power level triggers it. This information helps a Dacor-authorized technician narrow down which coil driver or board section has failed.
Take a photo of the display showing F1 to share with your service provider.
When to Call a Professional
Contact a qualified technician if:
- F1 returns consistently after multiple breaker resets — control board replacement required.
- Visible scorch marks or melted connectors found inside the unit during inspection.
- Cooktop is under Dacor warranty — board replacement must be performed by an authorized technician to maintain coverage.
