5 Reasons For Dacor Oven F1 Error [Solved].

Anybody who has used an oven (and that literally includes anybody on earth today!), knows how annoying are error codes appearing on the oven display.

A Dacor Oven F1 error is one of the most commonly experienced errors in Dacor ovens.

In the past few weeks, I received several complaints about this error, so I thought to jot down this blog post to answer the query in detail.

What Does the F1 error mean?

The Dacor Oven F1 appears due to an issue with the electronic control board of your oven. Possible reasons may include a software malfunction or a hardware failure.

Reasons for Dacor Oven F1 Error

Several common reasons cause the failure of communication between the control board and other components of the Dacor Oven, as I experienced in the past few years.

Reason 1: Steam or Corrosion Under Keypad:

Sometimes the keys under the keypad get dirty or corroded due to steam or other reasons. The Control board senses something stuck on the touch membrane and showed an F1 error on the screen.


  • Unplug the oven from the power supply.
  • Peel off the front of the keypad carefully.
  • Wipe the pad with the cotton bud and alcohol. Use a dryer to remove any moisture from it. Ensure the touchpad is completely clean and there is no corrosion, dirt, or steam on it.
  • Put the front part of the pad back in its place, and your error will be gone.

Reason 2: The Key is Pressed for a Long Time

If any key on the Dacor oven’s keypad is pressed for more than 4 minutes, the control board considers it an issue with the touch membrane and displays an F1 error on the screen. So, it can be a chance that someone, like your kid, has pressed the keys for a long time, and now the Dacor oven is showing the F1 error.


This problem can be solved by simply resetting the oven. Unplug the oven from the power supply and wait for 2 to 3 minutes, then bring the power ON again, and you will see the error is no more there.

Reason 3: Faulty Temperature Sensor

This error can also be caused by a problem with the oven’s temperature sensor located in the back of the cavity.

The temperature sensor is responsible for sensing oven temperature and sending that information to the control panel.

If it’s malfunctioning, it can cause an F1 error code to appear.


  1. Locate the temperature sensor. Normally it is located in the back of the oven cavity, near the top.
  2. Use a screwdriver or pliers to remove the sensor and unplug the connector.
  3. Set your multimeter to the “ohms” setting, also known as resistance.
  4. Touch the multimeter leads to the terminals of the temperature sensor, one lead to each terminal.
  5. Compare the multimeter’s resistance reading with the sensor specifications in the oven’s manual. If the resistance is out of range, it may indicate a problem with the temperature sensor.
  6. Replace the sensor and the connector and follow the manufacturer’s instructions to avoid hazards.
  7. Turn on the oven, and the F1 error has gone.

Reason 4: Firmware Issue

Firmware is software that controls the basic functions of the electronic control board in the oven. The firmware can cause the F1 error code to appear on the oven if there is a problem with the control board’s software.


I recommend you contact Dacor service to have them diagnose and troubleshoot the issue. They can also check if the firmware is up to date and, if necessary, update it to the latest version to resolve the problem.

It is important to note that if you suspect your oven has a firmware problem, you should not attempt to update it by yourself, as doing so incorrectly can cause more damage to the oven.

Reason 5: Faulty Control Board

It can be possible that your oven control board is corrupted and having a problem. If the control board is not working fine, the Dacor oven creates an F1 error code to indicate an issue with the board.


You need to replace the Control board with the new one because if you try to repair it, it can solve the issue temporarily, but in the future, the same problem will occur again. So, call a technician and install a new control board.


So, if I summarize the stuff, I would say that your Dacor oven is showing an F1 error code because there is a problem with the touchpad or the control panel. Or maybe your temperature sensor is not working fine, or your oven’s firmware needs an update.
