I appreciate your post, Haozhen!
From what you have described your Frigidaire range is displaying an error code of "F90" and your oven will not work. The "F90" error code stands for maximum door unlock time exceeded. This could be a problem with your door latch assembly or EOC (Electronic Oven Control). You would need to disassemble your range and test each component to assure it is providing an accurate electrical reading. This is not a simple DIY job and I would recommend having a professional technician out to perform a proper diagnosis and repair. Hopefully this information is helpful. -Matt
Error Code E90 typically means that you have a faulty motor door latch, lock motor assembly, door light switch or a defective EOC. You would need this to be diagnosed by a professional technician in order to properly repair the wall oven.
