The light bulb burnt out. It is located in the center of the fridge between the two doors. I'm not sure how to remove the bulb in order to replace it.

Most units use a door switch to turn the light on/off. Its usually located on the edge of the frame so the door closes on it to make/break the circuit. Switch could be bad or disconnected. Also your bulb may be bad, new doesn't not always mean good! Also look at the center contact in the bulb holder you may need to pull it up a bit for it to contact the bulb center pin. DO THAT ONLY WITH THE UNIT UNPLUGGED FROM THE HYDRO!

Hi Liz,
The reason they want you to disconnect the power is to prevent shock while installing the new bulb. The door switch controls the light in the freshfood so you really do not need to disconnect power, just be careful not to stick your finger into the socket. In most cases the bulb is hard to get securely screwed into the socket. The moisture in the refrigerator causes defect in the metal around the bulb socket and causes the bulb not to make a secure connectioin. So to repair your problem you can first off make sure the bulb is securely screwed into the socket. If it does not work you can check the voltage at the socket for the 110 volts. You can do this with any volt meter if you have one. Sometime the new bulbs can also be bad, its rare but possible. If you are not getting the proper voltage to the socket then you may need a door switch. If you have another light working in the freshfood then the door swith will not be the problem. The door switch is the only power feed swith to the socket, so one of those two will definately fixYa. Good luck and have a great day.

go to local service center & collect 15w bulb.

Hi!!

The light bulb is usually located in the center top of the fridge box, you may need to get on your knees and look up to see it. They usually just screw out, in case there is a plastic cover, just squeeze it and remove it. The replacement bulb can be found at Walmart or KMar it is call Appliance Bulb.

Good Luck!! Don't forget to rate this post!!

Try unplugging the opener and removing the bulb. Now pull out on the center contact in the light socket.

The likely culprit is the door switch on fridges in general. This because it is basically the only moving part in the circuit. Depending on it's location, it may be subjected to condensation, extremes of temperatures or even spilled liquids that dry and become sticky - resulting in the switch not popping out when the door is opened. Also inspect the light bulb socket itself for dampness or white, flaky dust-like particles. Do NOT attempt to clean the socket while the fridge is plugged in. These last two possibilities should be checked first, as the others are a little more involved.

If the door switch pops out with the door open - it means the internal workings of the switch are probably bad, or may be something else entirely. Locating the problem will require disconnecting the power cord and disassembling parts of the fridge in order to gain access to the switch terminals and related wiring. In the case of dampness or other debris in the light socket, it can be wiped clean now that the fridge is unplugged. Try a new bulb in the socket and plugging the fridge back in before proceeding. A meter and understanding of electrical test equipment along with the fridge's service manual will be needed to continue from here with the fridge unplugged again.

Even without a meter (and the rest of the items listed above) you could simply remove and replace the switch if it is suspect - and hope that it was the cause of the failure. Pay attention to orientation of the switch, any clips, screws or fasteners holding the switch in place. Disconnect wiring only after sketching or photographing the switch and the wires that are connected to each of the terminals. Remove and replace the switch and wiring. Plug back in and test the light.

Good luck - I hope this was helpful!

check light switch sticking or gone bad

You need to replace the door switch, as it is allowing the interior light to stay on, but also it's keeping the fridge section circulating fan from coming on, and that is what is really causing the interior to heat up.

It's located in the top hinge plate cover and you can test for faulty operation by removing the switch and connecting or disconnecting the wires together to see if your light goes out and the circulating fan starts to run. If so, the switch needs to be replaced.

The part number is #6600JB3007K and costs about $8.00. You can order it from several online sellers or at www.searspartsdirect.com

Here's a diagram of your fridge and the parts list with pricing.

Hope you found this very helpful and best regards!

take out bulbs make sure you unplug the refrigerator first, pull the center tab that touches the center of bulb, or check door light switch, if both lights are out

Did you leave the door open? check the light socket for shorts ..check the door switch the light will go off when to door is closed..
