The freezer has stopped freezing seems to be cool inside. The refrigerator is cold. How do you get to the coils to clean them.

Is there anything else I can check

Check to see if the condenser fan at the back bottom of fridge is running.
Is the compressor motor near that fan running.
Are the coils warm ,cold or hot. These are the coils you can clean by getting the dust off.

Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. stopped up? clear? ice in one spot . frost everywhere.
