Question about Microwave Ovens

Ge lvm1750dm1ww microwave

I went to replace the right side surface light bulb and noticed that the bulb was separated from the base of the bulb. As I pulled on it gently there was a zapping noise and sparks. When I tried to turn the lights off with the surface light switch it does not turn the lights off. What is wrong and what do I need to do get this fixed?

<-- I see and repair this problem on a regular basis. Details are here.

This failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line, as the warning label near the light socket advises.

This causes a failure on the control circuit board.

The lights can can be inoperable, or stuck on, or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.

You can get it your smart board repaired or order a replacement part number WB27X10935 here.

Whether you choose repair or replacement, the first step is to remove the controller assembly.

Here
is a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

Next, disconnect the strip as shown in the photo below, then remove the screws that hold your circuit board in the old frame.

Some connectors may have a lock. positivelock.jpg

Then carefully (since the display is made of glass) move your circuit board to the new frame, and reassembly is the reverse of disassembly.

If you choose repair, do not disconnect the keypad connector and do not remove the board screws. Leave the controller assembly intact.

That would almost certainly be a problem on the control circuit board. If the bulbs happen to short / blow out or if they are removed or installed while the microwave is still plugged in, there is often an arc which causes damage to the board. We repair regularly these boards for such problems for $32.50 nationwide.

The control circuits for the cooktop lights and the hood fan are spearate. The problem is indeed with the control unit. It's usually caused by either the filaments shorting when the lamp blows or by removing or installing the bulbs while the oven is still plugged into the power line. We regularly repair these nationwide for $32.50.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

Feel free to contact me directly for more information & help.

I have the same problem. The left one burns out within a couple of hours use, the other one lasts a couple of months and is then gone. This pattern has repeated over 8 years. I replace them every now and then and then just go without until I get the urge again to fix it. Maybe smaller lower wattage lamps are worth trying...

You could try the potato trick. Take a small to medium potato. Cut off an end of the potato. Press the cut end into the broken lightbulb and unscrew the rest of the bulb out.

Surface and night light bulbs


If the model number you have this listed under is correct, the bulb you need is part #AP2029997, made by GE. You can also purchase these bulbs at any hardware store. They are the half sized small base, 40 watt bulbs. If you can't find 40 watt, make sure you use a lower wattage rating. If you have questions, or if the model number is incorrect, please let me know. I hope this helps you.

Need new light bulb socket for GE spacemaker mircrowave


The bulbs are glued in at the factory. Unplug the microwave and see if you can remove the base of the bulb from the socket with needle nose pliers. You may have to twist the heck out of the bulb base but it should come out. If you do need a new socket it is available at www.geappliances.com under parts and accessories. Or call 1-800-626-2002 for GE factory parts

Light bulb replacement


Yes it just unscrews.  Unplug the microwave first!  Then use some needle nose pliers and put them inside the base open the pliers to put pressure on each side of the base.  Now turn the base counterclockwise.  Let me know how it turns out.

Surface lights


I also have had a problem with the glass part of the surface light bulb separating from the metal base when trying to change the bulbs under my G.E. Spacemaker Microwave.. I see someone used a carrot or potato but I had not seen this suggestion before I whittled one end of a wine cork small enough to insert into the metal part of the old bulb stuck in the socket. It also worked great and in no time I was able to get the old base out and replace the bulb. I'll save the cork for next time because it seems to happen to at least one of the bulbs everytime they need to be changed. DON'T FORGET TO UNPLUG THE MICROWAVE FIRST!
