The micro wave ( LG) carousel does not work

If the oven is still heating, but the carousel isn't turning, this problem is commonly attributed to a turntable motor that has worn out and may need to be replaced. The motor is attached to the center plastic piece (called a turntable shaft, turntable ring or coupler) under the middle of the glass tray. The following link explains how to access and replace the motor:

This is a very simple repair, that usually is not expensive. The price will be determined by the model and manufacturer. This repair can also be performed on an over the range model microwave oven WITHOUT uninstalling it.

You can refer to any of the following websites for comparison:

The first three sites listed have helpful exploded view diagrams to assist you with locating and properly identifying the part(s) you may need.

The average price for a motor is about $35 to $45. If your model number is not listed at all the sites, use the part numbers from the Sears site and use them for your search criteria. The model numbers don't always cross reference, but the part numbers do. If you need assistance identifying the correct part number, please post back with your complete MODEL NUMBER and I can assist you. I hope you find this information helpful.

NOTE: Even though the carousel may not be turning, you can still use the microwave while awaiting parts. You will need to physically rotate whatever you are heating about midway through the cook time to ensure even heating. Early model microwave ovens were not equipped with a rotating carousel and this was the common routine.

Bread is not rising. I have used two different mixes and neither rises....thwy both have yeast and i have not had this problem before with this brand. i am wondering if there is something wrong with the...

If the machine is heating up and there is no burning on the set heat that you have chosen then I dont think it can be the fault of the micro wave .
If there is burning on the sides or the bottom , then reduce the power rating and extend the timing. But if the cake seems fine, the batter is evenly cooked , the I suppose the fault can be the mix by itselt.
I recommend that you must try with new yeast, maybe the one you have used is old and ineffective. Use a good mix preferably good whipping.I am sure the next time your cake will be great.

Model JVM1650WH02 will shut off about 2 seconds or less into cook time. everything else works such as light and clock and sometimes the wave will cook.

magnetron is leaking internally, do not use until magnetron is replaced. the mag creates interference with the control board and resets it

Built-in Sharp Carousel II Microwave Convection Oven died.

There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.

Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.

Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.

Hope this has helped a little. Thanks for using Fixya!

Can i bake cookies on my sharp carousel with bake setting. can i use an ordinary micro safe plate or do I need something else?

yes you can bake cookies in the carousel on BAKE I suggest those new rubber looking bake plates help a lot to reduce the moisture that makes them soft.

I think they are silicone rather than rubber, i am sure you know the ones I mean

Sharp microwave stopped working

Is it totally dead? No display? Or just does not cook? If it made an unusual noise before it 'died' something probably shorted out.... You need an ohm meter to troubleshoot. If the fuse is open, switches and HV circuit need to be checked before replacing fuse. Sometimes on the convection Microwaves (not just Sharp) the fuse will 'rust' and open rather than blow. Or the fuse holder can over heat and fail.

Sharp Carousel Model#4A58: was cooking & made

If you have no power what so ever its probably the main fuse inside the mirowave. You'll have to take it apart. If you try this yourself unplug it then there are several screws around the cabinet of microwave remove them and make sure that they go back where you took them out from because they may or maynot be the same size or length. once you get the cabint off follow the plug wire up into the micro wave there may or may not be a fuse on the wire just inside the frame of the Microwave but it will be close when you find it take it out and replace with the exact size take it to a appliance parts store and get the replacement.

Microwave made a loud pop,won't heat,sounds like it's only on half power, makes a low intermittent hum

This is almost certainly a blown high voltage diode.

Please reply back with your brand and model number so we can help you.
