My fridge runs way too much - is this because it doesn't seem to be level?
A fridge motor is controlled by a thermostat - a device that reacts to temperature inside the fridge. So fridge motor starts/stops are completely agnostic to whether the fridge is level, the only practical consequence of fridge being non-level is extra noise.

The most likely reason for fridge motor running too often are the following:


loose gasket around the door - as the fridge gets older the gasket loses shape and no longer seals the interior letting cold air out and warm air in. This is addressed by replacing the gasket.
users putting hot stuff in - the fridge has to run for a long time to cool down a glass of hot water or a hot pan, only room-temperature or colder stuff should be put into the fridge to avoid that
users opening the door too often
