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 inside the freezer to observe the frost pattern. Light frost everywhere(NORMAL)
or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR
PROBLEM).
heavy frost-
If the evaporator coils behind the back panel of the freezer
are icing up because of auto defrost failure that will stop the circulation of
cold air and eventually affect the freezer too.
check defrost timer, defrost heater, defrost thermostat. In
most newer models the timer has been replaced by an electronic control board.
If the heater and thermostat are ok it’ll be the control.
You can turn the defrost timer till it clicks
and everything shuts down. The heater should now come on. If it does, replace
the timer. If it doesn't, check the heater and defrost thermostat. Turn the
timer again till everything starts back up to end the defrost cycle.
