What is an F90 Code on a Frigidaire Oven

An F90 code on a Frigidaire oven indicates that the unit has detected an error with the door latch. Several factors, including a damaged or obstructed door latch, incorrect installation of the door latch, or a problem with the oven control board, can cause this. If you see this code, it is essential to check the door latch and ensure it is properly installed and functioning before using the oven again.

How Do You Fix an F90 Code on a Frigidaire Oven

If your Frigidaire oven displays an F90 error code, there are a few possible causes and solutions. First, check to see if anything is blocking the oven door from closing correctly. The oven will display an F90 error code if the door is not entirely closed.

Ensure that there is nothing in the way of the door, such as a pot or pan, and that the hinges are not damaged. If the door seems okay, it may be an issue with the oven itself. Try unplugging the oven for a few minutes and then plugging it back in.

This may reset any error codes and allow the oven to function again. If this does not work, you may need to replace a component in the range, such as the control panel or main circuit board.

What Causes an F90 Code on a Frigidaire Oven

If you’re getting an F90 code on your Frigidaire oven, the control board senses that the oven door is not fully closed. This could be because the door isn’t locking correctly or something is blocking the door from fully closing. Either way, you’ll need to fix the problem before using your oven again.

A few things could cause your oven door to not close properly. First, make sure that nothing is blocking the door from closing. If there’s something in the way, like a dish towel or pot lid, move it out of the way and try closing the door again.

If that doesn’t work, one of the hinges on the door may be damaged or bent. This can happen if someone slams the door shut too hard, so check both hinges to see if they’re still in good shape. If one is damaged, you’ll need to replace it before using your oven again.

Once you’ve ruled out any obstacles or damage to the hinges, look at how well-aligned the oven door is when it’s closed. It should be flush with all four sides of the opening – if it’s not, something may prevent it from seating correctly in its frame. You may need to adjust the alignment of the oven door by loosening or tightening the screws on the hinge(s).


If your Frigidaire oven is displaying the F90 code, it means that there is an issue with the door lock assembly. Several things, including a defective door switch or a problem with the wiring, can cause this. Luckily, this is an easy problem to fix yourself.

Follow these steps, and you’ll have your oven working again.
