On the covered Dacor range, F1 means an element relay on the electronic oven control board that is stuck closed. First, cut power to the range or unplug it. Then: leave it without power for three minutes so that the board resets, then restore power. If F1 comes back, the electronic oven control board is replaced.
Differential
Likely causes of “Dacor range code F1”, and how to tell them apart
- 1
An element relay on the oven control board is stuck closed
What separates it The code shows, or a bake or broil element stays hot after the oven has been turned off
How to confirm Cut power to the range and see whether the code clears and the element cools
- 2
A one-off fault that clears on a reset
What separates it F1 appears once, perhaps after a power flicker, and does not come back
How to confirm Leave power off for three minutes, restore it and test the oven again
- 3
A power surge that upset the control
What separates it The lights flickered or the house lost power shortly before the code
How to confirm Reset the power and watch the next two or three uses
- 4
A relay that has welded shut
What separates it F1 returns at once after power is restored, and the oven heats without being asked
How to confirm The electronic oven control board is replaced
- 5
Heat soaked into the control after a long bake
What separates it The code appears at the end of a long, hot cook in a warm kitchen
How to confirm Allow the range to cool completely and try again, with the kitchen ventilated
Before you touch a setting
Record this first — changing settings destroys the evidence
- That the code is F1 and what the oven was doing when it appeared
- Whether any element stays hot or glows with the oven switched off
- Whether the code cleared on a three-minute reset and how long it stayed away
- The model and serial numbers from the range's data label

ReversibleCut power to the range or unplug it.
Correct only the documented fault domain
ReversibleLeave it without power for three minutes so that the board resets, then restore power. If F1 comes back, the electronic oven control board is replaced.
Cut power to the range
ReversibleUnplug it, or switch off its dedicated breaker, so that every element is dead before you do anything else.
Wait three minutes
ReversibleThe table says to leave the range without power for three minutes. That lets the electronic oven control reset fully.
Restore power and look at the display
ReversibleSwitch the power back on. A clean display with no F1 means the fault was a one-off, at least for now.
Test the oven briefly
ReversibleSet a short bake at a low temperature, and turn the oven off after a few minutes. Watch whether the element glows after you cancel.
Check that the elements cool
ReversibleWith the oven off, each element should lose its glow within a minute and the cavity should start to cool. An element that stays red is the stuck-relay fault.
Call for service if F1 returns
ReversibleIf F1 comes back, the electronic oven control board is replaced, because the relay that has stuck is soldered to it.
Model-specific
What is true of this model and not of its siblings
- The code on this page
- F1, an element relay on the electronic oven control that is stuck closed.
- Parts involved
- The electronic oven control board and the relays on it.
- Safety
- Cut power at the breaker if an element stays hot with the oven turned off.
Stop boundary
When this stops being a self-service repair
- !A stuck relay can keep an element energised, so call Dacor service if F1 returns after a reset
- !Cut power at the breaker if an element stays hot with the oven off, and do not use the range until it has been checked
- !Never open the control panel with the range connected to power

Common questions
What does F1 mean on a Dacor range?+
an element relay on the electronic oven control board that is stuck closed.
Is an F1 fault dangerous?+
It can be, because an element that cannot be turned off overheats the oven, so treat it seriously and cut power if anything stays hot.
Will resetting fix it?+
A reset clears a one-off fault, but a relay that has welded shut stays stuck and the code comes back.
Is the control board costly to replace?+
Yes, the electronic oven control is one of the dearer parts of a range, so compare the cost with the range's age.
Can I keep using the cooktop burners?+
Avoid using the range until the oven has been checked, since the same control board runs both.
