Dacor Range Error Code F2

The F2 code on a Dacor range indicates a Heating Mode High Temperature alarm. It is activated when the Electronic Range Control senses a runaway heat condition, meaning oven temperatures have exceeded safe operating limits without being brought back under control. The most common causes are a stuck relay on the control board, a faulty oven temperature sensor, or damaged sensor wiring.

Resetting the range by cycling power may temporarily clear the F2 code, but if the underlying cause is a stuck relay or defective sensor, the alarm will return once the oven heats up again. A reset alone does not fix the hardware problem. The root cause must be diagnosed and repaired to prevent the code from recurring.

Repair costs vary depending on which component has failed. A replacement oven temperature sensor typically runs in the range of $20 to $80 for the part. An ERC relay board or full control board replacement can range from $150 to $400 or more for the part alone. Adding professional labor will increase the total cost, generally ranging from $100 to $200 depending on your location and the technician.

No, you should not use the oven while F2 is active. The code indicates the oven has lost proper temperature regulation, which poses a risk of overheating the appliance and its surroundings. Stop using the oven until the underlying cause has been identified and repaired.

Start by checking the ERC relay board for a stuck relay, as this is the most common cause. If the relay is not at fault, test the oven temperature sensor and inspect its wiring harness for damage or poor connections. After completing any repairs, run the oven through a full self-clean cycle to confirm the temperature stays regulated without triggering F2 again.
