Error codeF3 / F-3
ApplianceWall Oven
Quick answer
F3 is the shorted oven sensor alarm on older Dacor ovens with the ERC electronic oven control. It appears only while a cooking operation is attempted.
Model compatibility: Dacor reuses codes across series and model years, so F3 / F-3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Alarm, shorted oven temperature sensor, read 16 temperature conversions in a row while a cooking operation is attempted.
F3, shown as F-3 in the display digits, is the shorted oven sensor alarm on Dacor ovens with the ERC electronic oven control. The control beeps and shows the code after it reads a short circuit in the oven temperature sensor 16 times in a row.
When F3 appears
The test only runs while a cooking operation is being attempted. If the oven is sitting in time of day mode, the F3 alarm will not be displayed.
What the manual tells you to do
Press the cancel key. If the alarm does not go away after that, the manual says to check the sensor and wiring, which is work for a technician.
Models and series
This is an older series. The code is documented for ERC ovens in the CPS/CPD, ECPS/ECPD, CPTS/CPTD, PCS/PCD, MCS/MCD and ECS/ECD families.
Codes that are easy to mix up with F3
F4 is the reverse sensor fault, an open oven temperature sensor. F2 is a high-temperature alarm for runaway heat.
