understand the F9 error code
If you see the F9 error code flashing on your LG oven display, you’ve got a problem. Specifically speaking, it means that your oven has actually stopped heating.
If your oven doesn’t reach at least 150 degrees Fahrenheit within the five minutes following its attempt to heat up, this error will flash on your oven’s display. This can be so frustrating if you were trying to bake cookies or roast dinner!
Overview of the F9 Error
Generally speaking, there are some pretty common issues that might cause an F9 error. Sometimes, it may just be a quirk—a simple glitch that confuses your oven’s computer.
Other times, it might be due to the fact that there is a part inside your oven that is in need of adjustment or replacement. Having an understanding of these issues will better suit you in making your decision about how you’re going to fix the problem.
Common Causes of the F9 Error
Some reasons that your oven may be flashing the F9 error include:
Faulty Relay Board
This is very common. The relay board helps control the heat inside the oven. If it’s broken the oven might turn on but not heat up properly.
Damaged Thermostat
The thermostat checks how hot the oven is. If it gets too hot, especially during a cleaning cycle, it may be damaged and quit working.
Broken Igniter
The igniter lights the gas that creates heat in a gas oven. If it is not working properly, your oven won’t reach an adequate temperature—hence this F9 error showing up on your display.
Thermal fuse issues
The oven will stop working if the thermal fuse blows and that usually happens when your electric or gas wall is too hot to maintain a safe current.
Knowing to these causes can help you troubleshoot and remedy the F9 error with ease. If you ever get this error, don’t panic! But there are worst-case scenarios, and if you get one of those error codes back from Directvodesa, the good news is that you can do a little bit to try to fix it yourself.
