GE Advantium Microwave Halogen Lightbulb Replacement (Do It Yourself)





Introduction: GE Advantium Microwave Halogen Lightbulb Replacement (Do It Yourself)

Note: This Instructable also works for the Kenmore Elite Speedcook Oven.

I have owned a GE Advantium oven for a little over two years now and I think it is about the neatest appliance that has come along in a long time (although it has been around for a while). I'll let you research why it is so cool. What is not cool is that in the two years I have had it, the lightbulb inside has burned out twice. I am not talking about the lamp that "browns" the food. I am talking about the lamp that allows you to "see" the food while the unit is running. If you think a light in a microwave is not so important, try heating up some soup without monitoring it...messy. Anyway, when the bulb failed the first time, I was at the tail-end of my warranty and with some convencing, was able to get GE to come and replace the bulb (they replaced a lot more parts than necessary, but for warranty work, who am I to complain?). Now less than a year later, the bulb is out again and is no longer covered by the warranty. Research at reports that a service call to make this repair can cost as much as $180! I replaced the bulb using information I obtained from that same website and the repair cost me $4.95 at my local Home Depot. Considering that this is a common problem, I am hoping this instructable will help MANY unfortunate GE Advantium and Kenmore Elite customers.

Step 1: Securing Power and Preparation

To do this instructable you will will need:
One number two cross-tip screwdriver
One G8 base, 120V, 25W, halogen bulb (GE uses a 130V, 20W)
One pair of vinyl disposable gloves

Once the bulb is replaced, and the door is open, as soon as the the unit is plugged back in, the light will illuminate.

The vinyl gloves are a precaution to ensure you do not contaminate the surface of the halogen bulb which can significantly reduce its longevity.

All parts were purchased at Home Depot.

Step 2: Remove the Grill

Now, you will need to remove the two screws that hold on the grill. They are the two screws that are closest to the edge of the unit. Once the screws are out, simply rotate the grill forward from the top. It will pop right out.

Step 3: Grill Out, You're Almost Done (can You Belive a Tech Charges Almost 200 Bucks to Do This?)

Now that the grill is out, there is a cavity on the left. The bulb is right under this sheet metal "floor" on the left. Towards the front of the floor, there is a single screw. Remove this screw and lift up the sheet metal floor to access the bulb.

Step 4: Bulb Replacement

Although the picture is poor, if you look inside the unit you will see a small shiny reflector that hides the bulb. If you place a flashlight in the microwave pointing up, it will be easier to locate the bulb. The reflector is simply a "pinch fit" into the unit. Sqweeze it a bit, making sure not to bend it and it will come right out where you can work with it.

Step 5: Replace Bulb and Relflector

Once the new bulb is in, replace the reflector. Re-secure the sheet metal floor with the single screw (it may stay up a bit in the worries) and replace the front grill.

You may want to test the bulb before the grill is back on. It's up to you.

Step 6: Restore Power and Pat Yourself on the Back

Once you plug the unit back in, it should come right on and immediately nag you to set the clock. Now that you have saved yourself $180, take your spouse out to dinner...or maybe just heat up some soup.

ONE FINAL NOTE: I have attached a pic of the bulb, GE uses for the unit. It is a different brand than the one I used. Hopefully, the new bulb will last more than a year.

    My GE Advantium is not the 120.
    It is GE
    Advantium MicrowaveModel #SCB1000KWW 01. Here is how I replaced the bulb.

    Buy the bulb in advance. WB25X10019. Lamp halogen G8-120V20W. It cost $12 from the appliance dealer.

    Arrange to have something to put the microwave on when you pull it
    out. Need to be able to pull it out over
    6 inches when taking the screws out in the back.

    Open the door and remove 4 screws (2 on each side). These are different from the other
    screws. That allows the microwave to
    pull out. My wife and I had no trouble
    lifting it and putting it on a wooden box we had at the time. Unplug
    the microwave

    The light is in the front of the top of the microwave. You can see holes in the top of the inside
    that allows light to come through. In order
    to reach it, you must remove the outside metal cover that covers the top,
    sides, and back. There are about 24-25 screws. When I went to replace the cover, I found
    that two were slightly different: they had finer threads and a lock
    washer. I think they came from the right
    side of the microwave (in the middle and at the bottom in the middle) and that
    is where I put them when I put it back together. So when you take out the screws, watch for
    two that are different from the rest and note the location. After all the screws are out, lift the cover
    off. It should come off fairly

    That exposes the back of the socket for the bulb with two wires going into the back of
    socket. Do not remove the enclosure for
    it. Just remove the two small screws on
    either side of the bulb. That allows you
    to pull the socket out and have access to the bulb. Avoid touching the bulb with your skin. I held it with the bubble wrap in which it
    came, but a thin plastic glove would work, as well.
    Simply push the two prongs of the replacement bulb back into the
    socket. Reinstall the socket. Plug
    in the microwave
    and see that the light goes on.

    Put the cover back on and replace the screws (getting the two with
    finer threads in the correct locations).
    Slide the microwave back in the enclosure and put in the four screws
    that hold it in.

    Thanks for the tutorial to replace the bulb, I couldn't do it last night but surely I will do today.


    I thought I'd make some comments on these GE Profile series microwave bulbs for the Advantium 120. I have model SCA1000HCC 03. This defines the type , color and month/year of manufacture. Yours could be similar and is key to the various parts you may need.
    Back to the bulbs. There are two that are likely to burn out and need replacing. These are, the surface night light at the bottom which lights the stove below the microwave and the harder-to-change, internal oven light which has been amply described here below. The oven lamp that works best is 120VAC (NOT 12 V as someone on another blog mentioned!) with 25W rating and a G8 base (the width of the prongs). These are readily available from Lowe's, Home Depot, Ace or similar. If you can get a pack of two or three, you will save a little money and have good spares. No need for another trip!
    The surface night light at the bottom of the microwave is a 120VAC, 20W bulb. It's better to get them from a local hardware store than say Amazon, unless you are buying other stuff too. Remember, you'll have to pay for shipping for a total purchase under $35 and have to wait at least several days.
    Finally, just as it's important to get the correct rating for the bulb and base width, make sure you wear latex gloves or use a tissue/paper towel to handle these. The number one cause for short lives is oil from fingers! This can reduce usage by as much as 50%.

    My Advantium 120 SC1000 does use a 12v lamp
    for the bottom light which illuminates the cook top and dims for a night light. It's a 20 watt,
    12 volt, T3, G4 base. It's sold at the big box stores as a "landscape
    lighting" bulb that is used in many landscape fixtures, RV fixtures, and
    interior cabinet lighting. Here is a link to a pair at Home Depot if
    anybody is looking for the bottom light bulb:



    My advantium 120 model has the glass touch panel on top -- not the removable grill unit in these pictures. Any idea how to access the light bulb in this model?


    Were you able to replace the light? If not, the following technical bulletin may help (see sections starting page 25 and 29):

    I didn't even know they were making them that way now. I'm sorry I have no idea. When I worked on my oven, I made it up as I went. Good luck.

    Hello! Do you know how to replace the interior cooking bulb? The one on the floor of the unit? I accidentally spilled food (melted cheese) into the grate and onto the bulb and I'm worried if I don't replace it it will either break or burn & stink

    Thanks for any help!

    Thank you for this instructable. I have an Advantium 120 that the "look-in-see" light blew years ago and I hadn't wanted to bother to dive in after hearing it was a tough thing to do. Ha, not as tough as I was worried about! I'm going to get it done this weekend. It'll be so nice to have light inside again.
    Oh my goodness! (lightbulb moment, ha, ha) I can do it sooner! You said the other bulb is the same? I'll just swipe the under microwave bulb! (It isn't used anyway because my micro isn't mounted up. I sits on my counter.)

    Once again, I used these instructions to replace my 25W halogen bulb inside my microwave.
    Having done it once before (2.5 years ago), certainly makes it easier. The hardest part was bending the metal flooring above the lamp receptacle to get at the darn thing. To make life easier, if you remove the black plastic grill inside the top portion (on the right hand side) by taking out a few extra screws, your access to the reflector and bulb housing is much easier. I also found that there is a tiny square glass piece, the size of a postage stamp, that actually fits over the metal screen that the bulb signs through. I was able to take it out and clean it and replace it. With the metal floor and the extra leverage provided, it was much easier than the first time, to put everything back together again and in the correct position. If the bulb is slightly skewed then it won't be quite as bright inside the microwave.
    As putnamcs suggests, replug the AC power BEFORE you reassemble to ensure it was the bulb that was the issue. If it comes on, you've done it!
    Depending on the height of your microwave, you will almost certainly need a stepladder or chair to do this repair.
    Another tip is when you buy a replacement bulb, get a spare or if you can get them in a pack of three, do so. It will save you money and ANOTHER trip to the store. The over-the-stove lamp underneath the microwave is the same type. Good luck all.
