Error codeF0 / F-0
ApplianceWall Oven
F0 in one sentence
When an older Dacor oven control reports F0 (it may be written F-0), it is saying that one of its input devices is either shorted or jammed. Two possible causes appear in Dacor’s Technical Manual: shorted wires, or a defective membrane switch.
Where the manual leaves the owner
There is no owner procedure for this code. Because the fault sits with the keypad inputs, the wiring and the membrane switch are what a technician would examine. One further detail from the manual: during its test sequence, F-0 is also shown for a stuck keypad when the tests are not completed within 30 seconds.
