Dacor Range Error Code Oven Knob Light blinks

A blinking oven knob light on a Dacor range indicates either a control board failure or that the oven's 12-hour bake time-out has been triggered. The 12-hour time-out is a safety feature that automatically ends a bake cycle after continuous 12-hour operation. If neither of those conditions applies, the control board itself may have an internal fault. A 5-minute power reset is the recommended first diagnostic step.

When the knob light is blinking, the oven's control board may not be operating reliably, and bake functions may not behave as expected. It is best to avoid using the oven until the cause is identified and resolved. If the blinking was caused by the 12-hour time-out, you can restart the oven normally after a reset, but a control board fault should be addressed before continued use.

Control board replacement on a Dacor range requires disconnecting power to the unit completely before beginning any work. The board is typically located behind the control panel, which must be removed to access it. All wire harness connectors should be documented or photographed before disconnecting, and the new board should be matched to the specific model. Because this repair involves the main control electronics, many technicians recommend professional service if you are not experienced with appliance electrical components.

A power reset will clear the blinking light if the cause is a temporary control board logic error or a triggered 12-hour time-out. Turn off power at the circuit breaker or unplug the unit and wait at least 5 minutes before restoring power. If the blinking returns after the reset, the control board has likely failed and will need to be replaced.

If the issue is only a 12-hour time-out, there is no repair cost involved since a power reset resolves it. If the control board has failed, replacement board costs for Dacor ranges typically range from around $150 to $400 or more depending on the model, with professional labor adding additional cost. Getting a diagnosis from a qualified technician before purchasing parts is advisable.
