The door open light is on and the fridge is not getting cold

It could be the button door switch that controls the light, or that a florescent lamp is being used in the cold fridge,

first look for an air vent in the bottom of the fridge(a small grill on the inside wall) & make sure nothing is blocking it, like bread eg: if there isn't then unplug your fridge & let it defrost, check the drain outlet in the back of the freezer, sometimes a small item like a frozen pea gets into the drain & the water freezes around it causing the air not to return to the freezer from the fridge, to push air into the fridge you must be able to get air out or it presurises,

There is probably an ice build up between the two sides of the appliance. There may also be a problem with the damper unit which controls the cold air coming from the freezer side to the fridge. The fridge is controlled by the freezer. Dependant on appliance. The door opens and closes letting the cold air go into the fridge and when the fridge is cold enough the door will close agin. This is not something that you will see happening it is normally concealed behing a diffuser.

have you checked the door seals, if it has split it won`t freeze 100% as warm air will get in and keep the temperature up, bit like leaving the door slowly open hth

you have a defrost problem.when you open your freezer door and look at the back panel look and see if their is frost built up.if so that means you do have a defrost problem.you will need to pull panel off and defrost coils.then you can check your defrost thermostat which is round and has 2 wires that go to it.it sits at the top of coils.see if it seperated.if so that is your problem also check defrost heater see if any breaks in it.if those check out then could be defrost timer which is located in ref.side.it would help to know what brand it is.it sounds like a side by side ref,but dont know what brand.

There is a duct between the freezer and refrigerator. Sometimes this duct blocks off with ice and won't allow airflow. Open your refrigerator door and check for air flow if there is none the duct needs to be defrosted. turn off freezer/ refrigerator and defrost.

Hi the reason for your noise coming from the fridge freezer is the plastic that is used in the design of your product is of a low quailty which reacts to the temp change and then as they get cold again they start to crack inside the frigde! Nothing to worrry about........
Hope this helps.....

Hi ,
ngafm at your service,
If its cold and frozen it may be that the door switch that activates this light in the case that the door is ajar, is faulty.
Or it may be that the temperature is dropping to slowly for you to see it by eye!
The whole purpose of the, "door ajar" light is to protect you food from spoilage and to warn you before it gets to warm!
Door ajar or not!!!
My advice is to fix the problem now no matter if it is only the switch causing a false alarm.
Or the worst case scenario !

You need hands on service!
