Light bulb burns hole in the plastic cover

The light bulbs on our LG LMVM1945SB get so hot they have burnt holes through the bulb cover. Has anyone else had this problem?

    I haven't had it burn completely through the light cover, but it has made a horrible brown bubble on it. That makes that side of the oven very dim compared to the other side. I replaced the bulbs with lower wattage bulbs, but haven't gotten a new cover. I need to find one.

    My bulb burnt out and I went to change it, a dark brown spot with a hole in it. Not sure what wattage bulbs they are, but plan on repalcing it and trying to find a new cover x 2. any ideas where?

    I have the same problem with a lmvm1945sw. I'm looking for parts and hoping there's an upgraded lens or something. Seems kinda dangerous in the there could be a fire from getting that hot.

    Anyone have any luck finding new covers? A website and/or part number would be very helpful. Thank You.

Same issue here. I just bought 4 covers from RepairClinic.com for $5.50 US each. I shipped them to my PO Box in Buffalo for an extra $6 bucks. Part number was 1206433

Hope this helps

How do you change the light bulb in a sunbeam microwave oven SGB8901?


First, you will probably have to buy the replacement light, which is a Z-187, 125v-20w lamp assembly, and a tamper-proof star key set, each of which are available for less than ten bucks on the web.Only other tool that you will need is a Philips head screwdriver, though you might find pliers helpful to remove the old lamp assembly from its spade connectors.
All the warnings of potential dangers of this project are valid, but taking care not to rush the project and only touch items as necessary will minimize risks.Needless to say, keep children and pets away from the disassembled oven, even after the plug has been pulled.
Unplug the microwave and remove the four tamper-proof screws along the back of the top cover, using the T20 key, and the three Philips-head screws along the side of the cover.Carefully lift up the cover of the oven.
Handling your new bulb by its base to keep moisture and body oils from the glassy portion, use it as a reference to locate the old bulb.It should be poking out of the top of the right side of the oven, upside down, with its spaded connectors sticking up.With luck, a sticker with a vague description of the bulb will still be stuck next to the light.Remove the Philips-head screw holding the bulb in place and pull out.Pull the connectors off the old bulb, and put them on the new assembly, being careful to keep the bulb as clean as possible.Put the bulb back in the hole, reinstall the screw, and put the cover back on the microwave by reversing the above instructions.
Enjoy!

GE JVM1640WB004 light bulbs break off when trying to replace them


GE uses a bulb that includes two flat pins. It looks like a bulb and removable socket, but it isn't. Just a way to cost you more. The bulb is removable from the top where it's mounted, and removed from the hole that it sticks vertically down thru. 1. You have to remove the unit cover to get to the bulb. 2. You have to unplug the connector to remove the bulb. 3. You have to squeeze two plastic pins, to extract the bulb from its location. This is not a common bulb; good luck finding one.

The microwave oven is not safe to use, the fire has compromised the interior of the oven, if you run the microwave it will start to arc and eventually short out the magnetron, because the white enamel paint has been burned away. If you have holes in the ceiling there is danger of radiation leakage, for safety reasons the oven should be replaced.

Have an installed GE Microwave jvm1870 with a burned out oven bulb. Have replacement bulb but can not see how to get to the old bulb to replace it.


From the owner's manual:

Cooktop Light/Night Light

On models JVM1850, JNM1851, DVM1850 and EMO4000, replace the burned-out bulb with a 120 volt, 40-watt incandescent bulb (WB36X10003), available from your GE supplier.

On models JVM1870, JVM1871, JVM2050 and JVM3670, replace the burned-out bulb with a 120 volt,
20-watt halogen bulb (WB36X10213), available from your GE supplier.

To replace the bulb(s), first disconnect the power at the main fuse or circuit breaker panel or pull the plug.

Remove the screw at the left edge of the light cover and push on the right edge of the cover to open.

Be sure the bulb(s) to be replaced are cool before removing.

After breaking the adhesive seal, remove the bulb by either gently turning (for models JVM1850, JNM1851, DVM1850 and EMO4000) or pulling straight out (for models JVM1870, JVM1871, JVM2050 and JVM3670).

Replace with the same size and type bulb.

Raise the light shield and replace the screw.

Connect electrical power to the oven.

To replace the oven light, first disconnect the power at the main fuse or circuit breaker panel or pull the plug.

Remove the top grille by taking out the screws on top of the grille that hold it in place and sliding the grille to the left (opening the door makes grille removal easier).

Next, remove the light cover.

On some models, the light cover is located in the center of the top opening.

Remove the screw that secures the light cover and lift the cover off.

On some models, the light cover is located at the left of the top opening.

Lift the cover off.

Pinch the clips that hold the light socket in place and lift the socket out.

Remove the bulb from the light socket by pulling straight out.

Replace with the same size and type bulb, then replace the light socket and cover.

Replace the grille and screws.

Connect electrical power to the oven.

Changing light bulb in microwave oven


If there's no obvious removable cover over the bulb (and the owner's manual doesn't address it) some disassembly may be required.

Always unplug a microwave before removing or installing any bulbs.

The screws you need to remove should be pretty obvious, but a special driver (such as a T20H type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

Is the Advantium Mod: SCA1000HCC03 the same as the SCA1001SS?


They are indeed the same bulb, a 10W halogen. Care must be taken not to touch the lamp, as the oils from the skin will shorten its life. In many recent models, the oven must be removed from the wall (a two-person job due to safety concerns) and the cover must be removed. The manufacturers consider this a "technician-only" type job to lessen their liability. You can find helpful exploded view diagrams of both ovens and order the bulbs here: http://tinyurl.com/gv383
