Dacor Oven Error Code F8 — Control Board / Clock Failure
What this means
Error code F8 on Dacor ovens indicates the main electronic control board has experienced an internal failure, often related to the clock circuit, EEPROM memory, or microprocessor. This code typically appears after a power surge, from a failing control board, or from corrupted internal programming. The oven may become non-responsive, display garbled information, or refuse to start any function. Dacor's premium ovens use sophisticated electronic controls, and F8 generally requires control board replacement.
Alternate codes: F08, Error F8
Step-by-step fix
4 stepsPerform a hard reset
Turn off the circuit breaker for the oven. Wait 10 full minutes to ensure all capacitors on the board are fully discharged and the memory is completely cleared. Restore power and check if F8 clears.
An extended 10-minute reset is important for F8 — shorter resets often do not clear the error because the EEPROM retains the fault.
Check for power supply issues
Verify the oven is receiving the correct voltage — 240V AC for electric Dacor ovens, 120V AC for gas models. Use a multimeter at the outlet or junction box. Also check that the circuit breaker has not partially tripped (flip it fully off and back on).
Dacor ovens are sensitive to voltage fluctuations. A partially tripped breaker can provide inconsistent voltage that confuses the control board.
Inspect control board connections
Remove the back panel or top panel to access the control board. Check all wire harness connectors for loose, corroded, or damaged pins. Reseat each connector firmly. Look for any visible damage on the board itself (swollen capacitors, burn marks).
On Dacor wall ovens, the control board is often behind the front control panel — you may need to remove the oven from the wall cabinet for full access.
Replace the control board
If F8 persists after resetting and checking connections, the control board must be replaced. Note your exact Dacor model number and order the correct replacement. Transfer all wire connections one at a time to the new board to avoid mixing up connectors.
Dacor control boards are among the most expensive in the appliance industry. Verify the diagnosis is correct before ordering — consider having a technician confirm.
When to call a professional
F8 almost always requires control board replacement, which is a significant investment on Dacor ovens. Have a Dacor authorized service provider confirm the diagnosis before purchasing the board.
