Answer to continue safely
Is it safe to keep using?
No. A control board failure means the oven cannot regulate temperature safely. Do not use until the EOC board is replaced.
Can I reset the code?
Yes. A 5-minute breaker reset sometimes clears F1 temporarily. If it returns within one bake cycle, the board has a persistent fault.
When to stop immediately?
Stop if you notice: Oven does not heat at all after reset, Display is blank or shows random characters.
Symptoms You May Notice
Oven stops heating mid-cycle
The oven ceases to heat during bake or broil and displays F1 on the control panel. Temperature drops rapidly.
Keypad unresponsive or erratic
Keypad inputs are ignored, produce random responses, or the display shows garbled characters after the fault appears.
Oven restarts without user action
The oven shuts off and restarts on its own, cycling power to the display and resetting the clock to 12:00.
Clock resets after fault clears
Even after a successful power cycle, the clock time reverts to default, indicating the EOC board lost its configuration data.
Possible Causes
Failed electronic oven control board (EOC)
The main logic board has developed an internal component failure from age or electrical stress, and can no longer regulate oven functions.
Requires ProfessionalPower surge damage
A voltage spike from the electrical supply damaged firmware or board-level components, corrupting the control logic.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle at the breaker
Turn off the dedicated 240V breaker for 5 minutes to allow the control board to fully discharge, then restore power.
If F1 does not return within one full bake cycle, the fault was a transient glitch.
-
2
Verify dedicated circuit
Check that the oven is on its own dedicated 240V circuit with no shared loads from other appliances.
Shared circuits can cause repeated board faults due to voltage fluctuations.
When to Call a Professional
Contact a qualified technician if:
- Control board requires replacement — not a DIY component on Dacor wall ovens
- Technician needed to verify wiring harness integrity before installing new board
