Dacor Range, Oven, Cooktop Error Code F2

F2 indicates that the Electronic Range Control detected a runaway heat condition, meaning oven temperature exceeded safe operating limits without being properly regulated. The ERC triggers this fault as a safety shutoff to prevent damage or hazard. The most common causes are a stuck relay on the control board, a faulty oven temperature sensor, or damaged sensor wiring.

No, the oven should not be used while F2 is present. This code indicates the oven could not control its own heating, which is a safety risk. Continuing to operate the appliance before identifying and correcting the cause could result in overheating, element or cavity damage, or a more serious hazard.

Repair costs vary depending on the failed component. An oven temperature sensor typically runs between $30 and $80 for the part. A replacement ERC or control board is considerably more expensive, often ranging from $150 to $400 or higher depending on the model. Adding professional labor will increase the total cost, generally by $100 to $200 or more depending on the technician and region.

Resetting the oven by cutting power at the breaker for a few minutes may temporarily clear the F2 code, but it will return if the underlying problem is not repaired. A stuck relay or failed sensor will continue to cause runaway heating, so the fault will reappear the next time the oven is used. A reset is useful for confirming whether the fault is intermittent, but it is not a fix.

Start by checking the relay on the ERC for any sign of being stuck in the closed position. If the relay is functioning correctly, test the oven temperature sensor resistance and inspect the full wiring harness from the sensor to the control board for damage or loose connections. Depending on which component has failed, the repair will involve replacing the sensor, the wiring harness, or the control board.
