Marcus Rivera Key Takeaways
- F2 means your Dacor oven thinks it's overheating, even if it feels normal
- The temperature sensor is the most common culprit behind this code
- You can reset the error by turning off power, but it will come back if the problem isn't fixed
- Professional repair runs from $150-$350 depending on which part needs replacing
The Bottom Line
The F2 code on your Dacor oven signals an overheating issue, usually from a faulty temperature sensor. Reset it by cutting power for 5 minutes, but if it returns, you'll need to replace the sensor or have a tech check the control board.
What F2 Actually Means on Your Dacor Oven
The F2 error code on your Dacor oven means the control board thinks the interior is running too hot. It's an over-temperature warning. The oven isn't necessarily scorching your food. More often than not, a sensor is giving false readings.
Dacor shares technology with Samsung, so the error code system follows similar logic. F2 almost always points to one of three things: a bad temperature sensor, a stuck relay on the control board, or an actual airflow problem.
Try This First: Reset the Oven
Before you start pulling panels apart, try a simple reset. The F2 code sometimes clears on its own.
- Press Cancel or Clear on the control panel
- If the beeping stops and the code clears, start a Bake cycle at 350°F and watch it
- If F2 comes back during preheat, you have a real problem
If Cancel doesn't work or the code immediately returns, cut power at the breaker. Leave it off for 5 full minutes. This forces the control board to fully reset.
Turn the breaker back on. If F2 is still there when the display powers up, or if you smell excessive heat near the unit, keep the breaker off and call for service. Don't keep running an oven that might actually be overheating.
Most Likely Cause: The Temperature Sensor
The oven temperature sensor (sometimes called an RTD) is a small probe near the back wall of the oven cavity. It tells the control board what temperature it is inside. When this sensor fails or its wiring gets loose, it reports impossible numbers. The board thinks the oven is 500°F when it's actually 350°F.
How to check it: The sensor is usually a thin metal probe with a two-wire connector. You can test it with a multimeter for resistance, but you'd need the spec sheet for your model to know what reading is correct. Most homeowners won't have that info.
What to look for physically: Pull the oven out if you can (or open the door wide and peer in). Is the sensor probe touching the back wall?
Is there any visible damage, melting, or corrosion on the connector? Sometimes pans or oven liners shift and push against the sensor. That's an easy fix.
When It Isn't the Sensor
If the sensor looks fine and F2 still appears, you might be dealing with a stuck relay on the control board. The relay is the switch that turns the heating element on and off. If it gets stuck closed, the element stays on and the oven overheats.
A bad keypad or touch panel can also trigger F2 on some models. If the error appears the instant you power the oven on, before you've even told it to do anything, the touch panel or the control board is likely the problem.
These issues are harder to diagnose without swapping parts. That's when you want a technician with the right diagnostic tools.
Did F2 Appear After Self-Clean?
Self-clean cycles push ovens to very high temperatures. If F2 shows up right after running one, let the oven cool completely before doing anything else. Give it an hour or two with the door closed.
Once it's cool, try the reset procedure again. If F2 is gone and stays gone, the extreme heat may have just caused a temporary glitch. Consider this a warning, though. If it happens again after another self-clean, the sensor or relay is probably weakened and will fail completely soon.
What the Fix Costs
| Part | Part Cost | With Labor |
|---|---|---|
| Oven temperature sensor | $30-$60 | $150-$250 |
| Control board relay | $100-$200 | $250-$400 |
| Touch panel/keypad | $80-$150 | $200-$350 |
Sensor replacement is the most common fix and the cheapest. Labor adds up if someone has to come out, but it's straightforward work.
Control board issues get pricier because the board itself costs more and requires some disassembly.
When to Call a Professional
Reset the oven yourself. Check the sensor for obvious issues. If F2 clears and stays cleared, you're done.
If the code comes back, or if it never cleared in the first place, call a Dacor-certified technician. The control board and relay are behind internal panels. You can create new problems poking around in there without the right knowledge.
Also call if you ever smell burning, see smoke, or notice the oven is actually running way too hot. Those are signs of a real overheating problem, not just a sensor glitch.
Keep It From Coming Back
- Don't line the oven floor with foil. It traps heat and can touch the sensor
- Make sure nothing is touching the back wall of the oven cavity
- Keep the area around the oven vents clear for airflow
- Don't run self-clean more than once a year unless your manual says otherwise
Most F2 errors come from the sensor reading wrong. A $50 part and an hour of a technician's time usually solves it. Don't panic when you see the code, but don't ignore it either.
