Vinotemp VT-155SBB stop working

hello

I have a Vinotemp 155 bottles wine cooler/fridge. purchased direct from Vinotemp in July 2020. the unit stop working on Mar 18, 2024. called and emailed vinotemp but i couldn't get any help from them. all they want is the serial number of the unit but i can find it and they can't tell me what to look for the serial number. does anyone know where i can purchase a PCB (power control board)? or anyone any suggestions as how i can get it fix?
