May be the fan. When I open the fridge door, light comes on, humming sound quits (motor of some kind - fan?)
Recycling - something turns on and off at nine-second intervals when the unit is on and the door is shut.
Opening the freezer compartment has no affect.
1. The noise that stops when the door is opened is the REAR Cooling fans and that is NORMAL
2. The Freezer doors have NO affect as they have NO light or light switch
3. Except for the REAR Cooling fans, The refer has NO other mechanical equipment that would cause a noise. So, as Chris pointed out, your Rear Fan Temp switch is SHORT cycling due to being defective.
4. NO harm will come to the refer. BUT, if the outside temps are above 75 to 80 degrees and that Fan Temp switch finally FAILS, odds are the refer will NOT cool correctly. The 1200 series NEEDS those fans to cool correctly. Doug
