A few days ago our refrigerator started making a humming noise.. And noticed some ice build up.. Would like to know the cause... Thank you
It sounds like you may have some type of defrost failure. You will want to pull the rear cover of the section where you are seeing ice build up and check to make sure that the evaporator is not impacted with ice. If it is then you will need to check the defrost sensors and heater to ensure them being good. If they are bad then replace them. If they are good then you w ill need to replace the control board.
