Interior lights not working on Samsung Refrigeration.

If it is a frost free freezer it could be the thermostat has a fault that has left the defrost heating panel switched on.

If the freezer is otherwise working correctly the refrigeration system will be trying to remove the heat from inside to the outside and so the compressor will be running continuously and the condenser will be quite hot.
If the condenser isn't hot it is likely the compressor is broken or the refrigerant has escaped...

Probably door switch is bad.

Try Manufacture Web Site , and double check that new bulb is not faulty

Could be just fuse blown, or headlight bulb blown, if both ok, check headlight contactor.

Hello;

My name is Peter. I am a retired field service refrigeration technician.

Before you change you door light switch. Lets check it out. First, if you have changed the light bulb, did you use a refrigeration light bulb. These bulbs sometimes are available in your local food market. If you used a household light bulb it eventually will fail. The household bulb is not designed for cold temperatures.

All appliances require specific light bulbs designed to the application such as, refrigerators, freezers, dishwashers, clothes washers and dryers. Of course they are more expensive $8.00-$10.00.

Ok, lets assume you have the correct appliance light bulb in your refrigerator. With the door open push on the door light switch. If the light comes on your door switch.

All door switches are basically the same they are plastic two contacts, except for one that is a 3 contact switch. The third contact controls the ice dispenser. This switch is on the left side of the freezer wall (Liner).

Ok, lets change a door light switch. Unplug your refrigerator. With a small flat head screw driver (or butter knife) wedge behind the plastic switch frame. Pop it out. Be careful, do not pull it out too far. You will see the two connectors. It may be difficult to remove the connector, so wedge them with a flat head screw driver (Or butter knife). Do not pull on the wires, just the metal connector.

Ok, with your particular model the contact switch is on the top of your unit. There are two screws holding the hinge cover plate. These screws are either Phillips head or hex head. Either 1/4" or 5/16" hex head. Remove the hinge top cover. You have one on each side. There is a connector. With a small screw driver, wedge into the connector to release it. The rest is yours.

You may have blown your bulb Get a 40 watt appliance bulb anywhere

Try to change the bulb, or there is no contact when u open or close the fridge..

Local Samsung service centre fixed it.

Chek the interior lights. Make sure they are turning off. One bulb will cause these symptoms. Is the bondensor coil hot( it's the coil under the unit. If it is, The fridge is working but has a heat source that won't quit or run out.
