Dacor Range F2 Error: Oven over-temperature
This dacor range f2 error code guide explains what this fault means for your Dacor appliance and how to respond safely. What F2 Means on a Dacor Range F2 means the oven exceeded its maximum safe temperature limit. The control board cuts the burner immediately. This often happens during self-clean cycles or if a gas […]

Answer to continue safely
Is it safe to keep using?
No. The range oven exceeded its safe temperature limit. Continued use risks fire and cabinetry damage.
Can I reset the code?
Yes. After full cool-down, a breaker reset may clear F2. Monitor closely during the next cycle.
When to stop immediately?
Stop if you notice: Do not restart the oven until it has fully cooled and the cause is identified, Stop self-clean cycles immediately if F2 appears — overheating during self-clean can crack porcelain or damage electronics.
Symptoms You May Notice
Food comes out scorched or heavily overcooked
Items in the oven are burnt or charred because the cavity exceeded the programmed temperature by a significant margin before the safety cutoff engaged.
Oven shuts off abruptly during cooking
The oven stops heating mid-cycle, the display shows F2, and the unit enters a safety lockout that prevents further operation until cooled.
Burning smell and visible smoke from cavity
Smoke or a strong burning odor emanates from the oven due to extreme temperatures scorching food residue, grease, or spills on the cavity walls.
Oven door and exterior surfaces abnormally hot
The door glass, handle, and surrounding cabinetry feel much hotter than normal because the cavity exceeded 590 degrees F bake or 990 degrees F clean threshold.
Possible Causes
Stuck-closed relay on the control board
A relay controlling the bake or broil circuit has welded shut from electrical arcing, keeping the heating element energized even when the board commands it off.
Requires ProfessionalRTD sensor reading low resistance
The temperature sensor reports lower resistance than actual, making the board think the oven is cooler than it really is and continuing to heat past the setpoint.
DIY PossibleSafe Checks You Can Do
-
1
Cool down and power off immediately
Do not open the oven door. Turn off the 240V breaker and allow the oven to cool for at least 45 minutes before touching or inspecting anything.
Opening the door during an over-temperature event releases a blast of superheated air. Wait until the exterior feels cool to the touch.

Test RTD sensor resistance after cooling
Once the oven is completely cool, disconnect the RTD probe and measure resistance with a multimeter. It should read approximately 1080 ohms at room temperature.
A reading below 900 ohms at room temperature indicates the sensor is drifting low, which would cause the board to overheat the cavity.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Gas valve appears stuck open or oven heats uncontrollably — gas valve replacement required
- RTD probe reads correctly but oven still overheats — control board replacement needed
- Code occurs every self-clean cycle without clearing — oven requires professional calibration
