Frigidaire Range Error Code dO

The dO code on a Frigidaire range stands for door open alarm during broil operation. It means the oven detected that the door was open while the broil element was active. The control may automatically shut off the broil element when this condition occurs. Closing the door and restarting the broil function is the standard resolution.

Yes, broiling with the door open is the underlying issue the alarm is warning you about. Running the broil element with the door open allows intense heat to escape into the kitchen, which can damage nearby cabinetry and pose a burn risk. The oven may shut off the broil element automatically to reduce this hazard. Always broil with the door fully closed.

If the fix is simply closing the door, there is no cost involved. If the door switch needs replacement, parts typically range from $15 to $60 depending on the model, plus labor if a technician is hired. A door gasket replacement generally costs between $20 and $80 in parts. Control board replacement, if needed, is the most expensive scenario and can range from $150 to $400 or more for parts alone.

Close the oven door fully within 30 seconds of the alarm appearing. If the broil element turned off before you closed the door, cancel the broil function, then restart it with the door completely closed. If the alarm keeps coming back even with the door shut, inspect the door switch and door gasket for damage, as either component may be preventing the control board from correctly detecting that the door is closed.

Closing the oven door is the primary action needed to clear the dO alarm. If the broil element shut off, you will also need to cancel and restart the broil function rather than simply reset the range. Performing a power reset by turning off the circuit breaker for 30 seconds can clear the alarm display, but if the door or door switch is not functioning correctly, the code will return when broiling is attempted again.
