Question

I have a Whirlpool GD25DFXFW02. Just recently, the fridge and freezer will suddenly stop working but still has power (lights and ice despenser continue to function). If I turn the thermostat down to 0 (off) and turn it back up to 3, the motor kicks back on and things are fine again (for a day or two). I'm guessing it has something to do with the thermostat.
