Freezer cold- Fridge Not, Loud Noise

Contact a professional. Sounds like either your damper door is not operating correctly and not letting enough cool air from the freezer enter, or there is an air leak that is making ice form .

this fan needs to run when the compressor runs,check fan blade for being jammed by ice if you have this much ice on back wall as ice will stall motor,if no fan there will be no cool air to refrige compartment also the defrost drain tray will fill with water then freeze over which in turn floods the freezer floor and refrige compartments cause it cannot drain to the pan in the bottom

It sounds like the evaporator fan is hitting ice that is built up on the evaporator coil. When it's making the noise, open the freezer door and see if it stops.
(Most models are wired so that the evaporator fan cuts off when the freezer door is open.)
Check the inside back, lower panel of the freezer for ice built up or frost on it. If there is, you have a defrost problem that is most likley a bad heater. It's located around the coil inside the freezer behind the panel you will be looking at. The defrost problem would explain the freezer not freezing ice cream.

If you have a frost build up on the interior back wall of the freezer, you have a defrost issue. This would include a bad defrost control, bad heater or terminator.
If there is not a frost build up then you may have a bad evaporator fan motor.

You will probably have to completely defrost fridge, overnight. The air duct between the freezer and the fridge is probably frozen.

Hi Thanks For The Question. Is The fridge Cold.If Yes Check In Fridge For The Noise. If Not In Fridge Pull Fridge Away From Wall, Remove Back Panel Clean All Coils Thanks The Appliance Doc

Defrost problem. Either defrost heater, defrost thermostat, or defrost timer is bad.

Yes, replace the defrost heater and melt the frost with a hair dryer which is blocking air flow over the evaporator. The frost blocked coils (behind the freezer wall ) results in very poor cooling.

Light going out is a separate problem. If the freezer is still working and the fan in the freezer operating check for frost on the back wall. If there is frost on the back wall you have a defrost system problem.
Possible open heater, bad timer, or defrost thermostat. If the freezer is not working check for power to it. Reset the breaker if necessary.
If the light went out because of some power loss the freezer would not be working.

ou most likely have a defrost problem is there a large build up of frost in the back wall; of the freezer??
