Dacor Range F10 Error: Control board internal fault
This dacor range f10 error code guide explains what this fault means for your Dacor appliance and how to respond safely. What F10 Means on a Dacor Range F10 signals an internal self-diagnostic failure on the main control board. The board has tested its own memory and output circuits at startup and found a critical […]

Answer to continue safely
Is it safe to keep using?
No. A critical control board failure prevents safe operation. All oven functions are disabled.
Can I reset the code?
No. F10 represents a board-level failure. Extended power cycling rarely helps — board replacement is needed.
When to stop immediately?
Stop if you notice: Do not use the oven — a board with an internal fault cannot guarantee safe temperature regulation., Stop attempting resets after five failed attempts — no number of resets will recover a physically damaged control board..
Symptoms You May Notice
Oven completely unresponsive to all inputs
No cooking mode starts, no temperature responds, and no function other than the clock or display backlight may be active — the control board is alive enough to show F10 but nothing else.
F10 appears immediately on power-up
The moment power is restored the display shows F10 without any user input — the board performs a self-test at startup and fails it before accepting any commands.
Clock resets to 12:00 repeatedly
The board loses its time setting every time power is cycled, indicating non-volatile memory on the control board has been corrupted or has failed.
Random functions activate without input
Before settling into a permanent F10 lockout, a failing control board may randomly activate the timer, clock, or oven modes on its own — a sign of processor instability.
Possible Causes
Power surge damaging the control board
A voltage spike has corrupted the firmware or physically damaged a control IC on the main board. Dacor Modernist (DOP) series ranges are particularly sensitive to surges due to their multi-module architecture.
Requires ProfessionalFailed EEPROM or processor on the control board
The non-volatile memory chip (EEPROM) storing board configuration has failed, causing the board to fail its own startup self-test with F10 on every power cycle.
Requires ProfessionalSafe Checks You Can Do
-
1
Extended hard reset
Turn off the circuit breaker for 10 full minutes. This is longer than typical resets and ensures all board capacitors fully discharge. Restore power and check whether F10 clears. If the range operates normally for a full cook cycle, the fault was a transient processor hang.
If F10 clears but returns within minutes or on the next power-on, the board failure is progressive and replacement is needed.

Verify power supply quality
Check that the range is plugged into a properly grounded 240V outlet with no shared loads. Voltage irregularities from a shared circuit are a common cause of repeated control board faults. If a recent storm preceded F10, the outlet and breaker should also be tested.
A whole-home surge protector or a dedicated range surge protector significantly reduces the risk of board damage recurrence.
Tools required
When to Call a Professional
Contact a qualified technician if:
- F10 returns on every power-on regardless of reset duration — main control board requires replacement.
- F10 appeared immediately after a known power surge — board should be tested for secondary damage before replacement parts are ordered.
- Dacor Modernist (DOP) control boards are model-specific and must be sourced from authorized Dacor parts channels.
