Dacor Oven Error Code C90

C90 is a notification code indicating that the oven's power was interrupted and has since been restored. The control board displays this alert so the user is aware that any active cooking program was cancelled during the outage. It is not a component failure code and does not indicate a malfunction within the oven itself.

Yes, it is safe to use the oven after a C90 code. The code is purely informational and does not indicate a safety hazard or a fault with any internal component. Simply clear the code and resume normal use.

In most cases, clearing C90 costs nothing because it only requires pressing a key after a power outage. If the code is caused by a loose wiring connection, an electrician's service call typically runs in the range of $75 to $200 depending on your area. If a control board replacement is ultimately needed, parts and labor costs generally range from $300 to $600 or more for a Dacor unit.

Press any key on the control panel to clear the C90 code. Once cleared, the oven will return to normal operation. You will also need to reset the clock, as the time is lost whenever power is interrupted.

Pressing any key clears the C90 code immediately, and it will not return unless another power interruption occurs. If the code keeps coming back without a known outage, the underlying cause is likely an unstable power connection or circuit issue that should be investigated.
