What Does F3 Mean on a Microwave?
The F3 error code on a microwave typically indicates an issue with the temperature probe or thermal sensor. This code is a fault signal from the microwave’s electronic control system, meaning something is preventing the microwave from working properly, usually related to the temperature sensing or circuitry.
Microwaves rely on various sensors to ensure they heat food evenly and safely. The F3 error often arises when the temperature probe or humidity sensor malfunctions, providing incorrect feedback to the control board. This leads the microwave to enter an error state and display the F3 error code.
Why Does the F3 Error Occur?
The F3 error can happen due to several reasons, including:
- Faulty temperature probe or thermal sensor
- Power failure affecting the sensor connections
- Loose connections or stuck buttons on the control panel
- Malfunctioning humidity sensor or touchpad panel
It’s important to note that while the F3 error doesn’t always signal a major issue, it should still be addressed promptly to avoid further complications.
How to Fix Common Microwave Errors: 5 Best Steps Guide
If you’re seeing the F3 error on your microwave, follow this step-by-step guide to troubleshoot the issue.
1. Reset the Microwave
The first step is reset the microwave and you should try is a power reset. Unplug the microwave from the power source and leave it unplugged for about 5 minutes. This allows the internal components to reset, which may clear the error code.
2. Check the Temperature Probe
If the reset doesn’t work, the next step is to inspect the temperature probe or thermal sensor. The probe might be disconnected, damaged, or misaligned. If the probe is damaged, you may need to replace it. For this, you may need a technician for assistance.
3. Inspect the Control Panel
Sometimes, the control panel or touchpad panel can malfunction. Look for stuck buttons or any visible signs of damage on the panel. Cleaning the control panel with a mild cleaning spray can sometimes resolve minor issues.
4. Check the Circuit Board
If you feel confident in your DIY repair skills, inspect the control board for any visible damage. Loose wiring or burnt components can cause malfunctioning sensors and lead to the F3 error. Be sure to disconnect the microwave from the power source before inspecting the board.
5. Replace Faulty Components
If none of the above steps work, you may need to replace the temperature probe, sensor, or control panel. Consult your microwave’s user manual for specific replacement parts, or consider calling an appliance technician for professional help.
How to Clear the F3 Error Code?
Clearing the F3 error code is usually done by fixing the underlying issue, such as the temperature probe malfunction. However, a simple power reset can sometimes be sufficient to clear the code temporarily.
Steps to Clear F3 Error Code:
- Unplug the microwave from the power source.
- Wait for at least 5 minutes.
- Plug the microwave back in.
- If the issue persists, follow the steps above to inspect the temperature probe, control board, and other components.
Why Is My Microwave Beeping and Showing F3?
If your microwave shows an F3 error and keeps beeping, it’s likely due to a faulty connection or a sensor malfunction. The microwave is designed to alert you when there’s an issue, and the beeping is simply a warning signal. The constant beeping means the microwave is unable to complete its operation properly and needs attention.
Why Does My LG Microwave Say F3?
If your LG microwave shows an F3 error, it could be due to the same causes mentioned earlier, such as a malfunctioning temperature probe, thermal sensor issues, or even power fluctuations. For LG microwaves, make sure to consult the user manual or contact LG customer support for model-specific troubleshooting steps.
Preventing Future F3 Errors
Preventing the F3 error on your microwave involves regular maintenance and careful use.
Tips for Preventing F3 Errors:
- Clean the microwave regularly to avoid dirt or debris affecting the control panel or sensors.
- Ensure proper ventilation around the microwave to prevent overheating, which can cause sensor malfunctions.
- Periodically check connections and make sure the temperature probe is properly installed.
- Avoid power surges by using a surge protector to prevent damage to the microwave’s electronic control.
The Top 5 Microwave Error Codes You Need to Know About
While the F3 error is common, there are other microwave error codes that users should be aware of. Here are the top 5 microwave error codes and their meanings:

According to my experience, encountered the F3 error on my microwave last year when I was reheating dinner. The microwave suddenly stopped, and the display showed “F3.”
After some quick research, I learned that the F3 error typically indicates an issue with the temperature probe or thermal sensor. I unplugged the microwave for a few minutes to reset it, but the error persisted. Upon closer inspection,
I found that the temperature sensor had likely malfunctioned, which required a technician’s visit to replace it. After the replacement, the microwave worked perfectly again, and I learned that these sensors can sometimes fail due to age or wear.
A study from the International Journal of Appliance Technology discusses common microwave error codes like F3, which often points to a failure in the temperature probe or thermal sensor.
The research highlights that microwaves depend heavily on sensors to regulate cooking temperatures, and when these sensors malfunction, the microwave can no longer function properly.
The study emphasizes that understanding these fault codes is crucial for efficient troubleshooting, as it helps users identify specific issues and avoid unnecessary repairs.
The F3 code is seen as a diagnostic tool for pinpointing sensor-related problems and ensuring more accurate repairs.
