Works intermittently. It will go okay for a while then makes a buzzing noise while it runs. Then a day or two later the fridge section stops cooling. It will start working again in a few hours or the next day.
Have you noticed more frost in the freezer than usual? It sounds like you may have moisture building up and freezing around evaporator fan. The fan blade hitting ice will cause the buzzing until it stops it completely or the evaporator clogs with frost and blocks airflow. If you have frost on food in freezer, check the door seals and make sure nothing is keeping doors from closing completely if you release them about 6" from cabinet.

I think I have a similar problem. The noise I hear is a vibration or humming sound. I took the back panel off the inside of the freezer to get to the fan. When i press on the fan assembly, the buzzing stops. I've tightened all the screws and tried putting rubber spacers between the fan assembly and the freezer walls but the buzzing persists, but it's intermittent. Are these fans multi-speed, or is this a result of condensation/frost build up on the fan itself?Fan on the way out? Fridge out of balance? I'll try anything to stop the hum.
