Is the fridge getting warm ???? Mine will sometimes not light on the first try. When that happens the Check Light comes on. But, given some time it will try to light again and the light goes off. It will try to cycle 3 times before it shuts down for good.
Are you maybe watching it so close that you just happen to be there during the times when it doesn't light on the first try ??
I watch mine to closely sometimes also. If the red light comes on I start to panic. But, I have learned to give it some time and see if it will relight on the second or third try and then the light goes off.
