My model refrigerator is kitchenaid KFIV29PCMS02. It started with ice maker not working properly. Watery ice. Then the freezer started icing and freezing up to the motor fan inside the freezer and making noise cause the ice was reaching the fan. Defrosted a couple times and now the freezer isn’t getting cold enough to freeze anything. It’s cool and the refrigerator is cool but freezer is not freezing. I replaced the defrost thermostat. Should I replace the compressor inverter board next? It’s frosting up only on the right side.
