Thank you for your question. I'm sorry you're having this problem with your fridge. This can be a complicated unit to check and a technician will usually be required. If it’s not cooling at all, it first needs to be determined if the compressor is running. If the compressor is running, the problem will probably be in the seal system or with the compressor. It could be a low charge, a restriction or the compressor may not be pumping properly. These are checks a technician will be required to make. If the compressor is not running, it could be due to the compressor itself, the board or the inverter. These can be some complicated checks to make and I recommend having a technician check this.
