When an oven starts displaying the F3 error code, it can be frustrating and confusing for many homeowners. The F3 error code is a common issue that affects many oven brands, including Maytag, Whirlpool, and Kenmore. The error code usually indicates that the oven’s temperature sensor has run into problems, and the oven will stop working until the issue is resolved.

Fortunately, fixing the F3 error code is not as complicated as it may seem. In most cases, it can be resolved by power cycling the oven or replacing the faulty temperature sensor. Power cycling involves unplugging the oven from the outlet for a few minutes and then plugging it back in. This simple solution can often fix minor bugs that cause the F3 error code to appear.

If power cycling doesn’t work, replacing the temperature sensor is the next step. The temperature sensor is responsible for regulating the oven’s temperature, and a faulty sensor can cause the oven to display the F3 error code. Replacing the sensor is a straightforward process that can be done with basic tools and a little DIY knowledge.

What is an F3 Error Code?

When an oven displays an F3 error code, it usually indicates that the temperature sensor has malfunctioned. The temperature sensor is a small device located inside the oven that measures the temperature and sends a signal to the oven’s control board. If the temperature sensor is faulty, it can cause the oven to display the F3 error code and stop working properly.

There are several reasons why the temperature sensor may malfunction. It could be due to a wiring issue, a damaged sensor, or a problem with the oven’s control board. Sometimes, the F3 error code may be the result of a minor bug in the system, and a simple power cycle can reset the oven and fix the issue.

If you are experiencing an F3 error code on your oven, it is important to troubleshoot the problem as soon as possible. Ignoring the issue can lead to further damage to your oven and may require costly repairs or replacement.

Causes of an F3 Error Code

When an oven displays an F3 error code, it typically means that there is a problem with the temperature sensor. Here are some common causes of an F3 error code:

  • Bad connection between the temperature sensor and the electric oven control or the wire/sensor harness.
  • Wire damage or inaccurate ohm readings.
  • A faulty temperature probe that is not able to maintain the set temperature in the oven.
  • A short-circuit somewhere in the wire harness leading to a button.

If the temperature sensor is not working correctly, it can cause the oven to overheat or underheat, which can lead to burnt or undercooked food. In some cases, the oven may shut off completely to prevent damage.

It is important to address the root cause of the F3 error code as soon as possible to prevent further damage to the oven and to ensure that it is safe to use.

How to Fix an F3 Error Code?

When your oven displays an F3 error code, it means that the temperature sensor has failed or is malfunctioning. This can cause your oven to stop working or not heat up properly. Fortunately, fixing this issue is not too difficult, and can be done in a few simple steps.

The first thing you should do is turn off the power to your oven. This can be done by unplugging the oven or turning off the circuit breaker that powers it. Once the power is off, you can check the temperature sensor to see if it is damaged or not functioning properly.

If the temperature sensor is damaged, you will need to replace it. You can purchase a replacement sensor from your oven’s manufacturer or from a local appliance parts store. To replace the sensor, you will need to locate it inside the oven and remove it from its housing. You can then install the new sensor in its place, making sure to connect it properly.

If the temperature sensor is not damaged, it may just be dirty or covered in grease. In this case, you can clean the sensor using a soft cloth or sponge and some warm, soapy water. Be sure to dry the sensor thoroughly before turning the power back on.

Once you have replaced or cleaned the temperature sensor, you can turn the power back on and test your oven. If the F3 error code is no longer displayed and your oven is heating up properly, then you have successfully fixed the issue.

Preventative Measures

While fixing an F3 error code in your oven can be a nuisance, there are some preventative measures you can take to avoid the issue altogether.

One of the most important things you can do is to keep your oven clean. Food debris and grease can build up over time and cause issues with the temperature sensor. Regularly wiping down the inside of your oven after each use can help prevent this buildup and keep your oven running smoothly.

Another preventative measure is to avoid using your oven’s self-cleaning feature too frequently. While this feature can be convenient, it can also put a lot of stress on your oven’s components and increase the likelihood of errors like the F3 code. Instead, try to clean your oven manually as often as possible.

It’s also a good idea to have your oven inspected and serviced by a professional on a regular basis. A technician can check for any potential issues and make any necessary repairs before they turn into bigger problems.

Finally, always make sure to use your oven according to the manufacturer’s instructions. Overloading your oven, using the wrong cookware, or setting the temperature too high can all cause issues with your oven’s temperature sensor and lead to an F3 error code.
