Yes, if the filters are clean, the coils are clean, and it is still freezing up in cooling mode, then it is low on refridgerant.

Your split system is an inverter model. In it the compressor is powered not simply from the mains thru a relay but from a special and very complex set of converters: a rectifier to convert the incoming AC current to DC and then uses pulse-width modulation of the DC current within an inverter to produce AC current of a desired frequency to power the compressor.
In your case the unit that provided the final AC current to the compressor has failed. The fact this happened a few days after you have started using it is a clear indication of manufacturing defect - some of the electronic components used in that inverter were of a low quality and they haven't been able to cope with the stresses so they failed.
This is something that only the dealer (and its repair crew) can solve and it's covered by the warranty - time to call them. And in the mean time disconnect the unit from the mains.

My oven show the f90 code and the door can't close, the oven can't work, please help me. thank you

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

Panasonic fault codes

I found this error. The simple possible resolution is to reset the circuit breakers feeding this unit and/or replace possible blown fuses. Other possible problems may be too involved therefore a professional should be hired. Just a warning, this problem could get expensive.
