Question about LG Microwave Ovens

1 Answer

I have an LG solardom microwave and when I want to heat a small amount of liquid, it sparks and the base(not the turntable) of the microwave gets hot.

The sparks are usually under the turntable and sometimes there are little flames too...

Quite often this is due to grease or food particles stuck somewhere in the cavity of the oven or stuck on or behind the waveguide cover.

It may also be in the area of the turntable support, coupler, or motor.

SOURCE: Microwave turntable won't stop running

This is usually caused by either a bad door switch, but may instead be a loose door switch mount or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

It's probably the motor, but possibly the coupler.

One quick check is to remove the turntable and support / roller ring and try to turn the coupler. It should be a little hard to get started, then you should hear a whirring sound, not a clicking or grinding, which would indicate a bad motor.

If the coupler turns loosely with no resistance, then it's probably bad.

Here is my text on replacing couplers, which had steps which are necessary when replacing motors. Note that if yours is a built-in model, ignore the part about turning it on its side *grin*

NOTES ON REPLACING TURNTABLE COUPLERS

Copyright 2007 by William E. Miller - MicrowaveDisplay.com

UNPLUG THE OVEN FROM THE WALL FIRST OR YOU WILL EXPOSE YOURSELF TO LETHAL VOLTAGES!

Note that I am not encouraging you to work on electrical items if you are not qualified, and I assume no liability for any consequences of your decision to do so.

When replacing the turntable coupler on most models, it is necessary to loosen or remove the screws that mount the turntable motor to the bottom of the chassis.

It is usually easier to do this with the microwave oven on its right (heaviest) side because you will need two hands for alignment.

Be sure to put a towel or similar cushion on the work surface to avoid scratching the oven wrapper (oven cover) or the work surface.

It is not necessary to remove the wrapper or the wires from the turntable motor itself, but you may need to remove a small metal duct covering the turntable motor if your oven has one.

It should only be held on by one or two screws.

Although a broken coupler may come out easily or even fall out, the new coupler will not go in without at least loosening the turntable motor.

Look at the hole in the new coupler. You'll notice it has (most do have) a flat side to it. That flat side will line up with the flat side on the motor shaft.

When the old coupler is out and the motor is loose, you can ease the new coupler in the hole with one hand while turning the coupler very slightly back and forth as you gently push the motor toward it. Do not force the part in.

When the coupler has mated properly with the motor, you should feel it go in.

Be sure it's right, or you may break the new coupler or bend the mounting ears of the motor when you attempt to tighten the screws.

Reassemble in reverse order.

SOURCE: Microwave won't heat, and turntable doesn't turn

All the parts you mention are very inexpensive, but yours does not have a triac.

It could be the cook relay, but it's more likely to be a switch.

Looking at the schematic, it's probably a bad primary interlock (upper door switch) or maybe its mount is bad.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you have a broken mount, it's usually more economical and safer to just add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

There may also be a "mini-manual" hidden inside the unit behind the control panel or elsewhere, which is very helpful when troubleshooting & testing.

Quite often this is due to grease or food particles stuck somewhere in the cavity of the oven or stuck on or behind the waveguide cover.

It may also be in the area of the turntable support, coupler, or motor.

The waveguide cover (also called a spatter shield) is usually about the size of a playing card and often held in place by a plastic rivet.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The waveguide cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

If your waveguide cover is burned, it will need to be replaced. It provides important protection for the magnetron.

Oven heats, but light, fan and turntable do not come on.


Hi Ted

many microwaves have safety mechanisms to reverse, or stop the turntable if it senses resistance to the turning. This is done both because
  1. the turntable is usually driven by a small motor with a gear reduction transmission to get more torque on the glass platter and your food, and if something resists the turning, it can damage the gear train or belt if it keeps running.
  2. if you have something with liquid in it and it hits a wall, it could tip over, possibly spilling scalding liquid all over and maybe surprising the person who opens the door.
In some cases, it'll just stop and then try again the next time you run the microwave. The banging on the case sometimes turning things back on suggests that either something in the turntable mechanism is awry, or that there is a common hot wire, ground loop, or possibly fuse for the light/fan/turntable.

the manual for the oven doesn't really say anything about this.

You can see generic intructions on looking for an internal fuse here
Panasonic Microwave NN CT552W has no power plug fuse ok Has it got thermal... . Please, in particular, make sure you unplug the oven before opening anything. This is one of those devices where defeating the interlocks and having it turn on can seriously hurt you.

With regard to the turntable, in particular, it's really easy over time for exploded spaghetti sauce, spilled cocoa, and overmelted butter to have run down into the indentation in the middle of the bottom of the oven cavity. Remove the platter. Is it clean in there? Does it look like the 'this person never flosses' picture for mechanical rotors? If so, start with some kitchen cleaner and a washcloth damp (not soaked) with hot water. Let the cloth steam /warm the area a bit, wipe it down. repeat if necessary. If there's a lot of cruft built up there, that could be keeping you on the edge of safety shut-down.

Good Luck!

Sounds normal when running but will not heat food and turntable does not work


You didn't specify a particular model, but the no-turntable and no-power symptoms are likely linked. Many microwaves have sensors to the turntable motor to tell if something being heated has been run into a wall (round turntable in a rectangular box, it can happen), Depending on the model, it may reverse direction, or it may just stop turning. This is both to keep from mucking up any reduction gearwork likely at work to turn some small motor spinning at a higher speed into a big table with a few pounds of food turning slowly with reasonable torque. It also will stop so that things won't get tipped over - no good to anyone if a poorly chose top-heavy bowl full of scalding liquid gets tipped over, flooding the microwave and burning whoever opens the door.

So... I'd remove the carousel plate, if possible, and see if the base is all gummed up with old spilled, ultra-baked-on crust or gummy residue. if so, between washcloths with scalding water and some gentle cleaner, like Simple Green, try to clean up the area and remove what might be freezing the spin shaft up. See if you can wiggle the shaft or turn it slightly with fingers or a small pair of pliers. If not, there may be more stuff gummed up further down the shaft. Don't expect to just spin it, it's probably tied to a motor with a belt or gear assembly that will put the mechanical advantage working against you.

After that - you can try unplugging the oven for a few minutes, in case it's either overheated, or in a 'safe' mode, or look for an owners manual for your specific model to see if there's a button combo to reset things, (or accessible fuses).

Good Luck!

Does the microwave rotate during cooking?


Most microwave ovens have a "stirrer" blade run by a small pancake motor to help avoid standing waves and hot spots inside the microwave cavity. And most modern microwave ovens have a turntable to turn the food, to provide even more even-distribution of heating.

Microwave lights, clock, and everything works except when you press start, it just counts down like its cooking, but the microwave is actually not on. No hum as usual or plate rotating. It just counts...


Hi, one of the most common reasons why the turntable won't rotate is that the microwave isn't clean. The turntable guide and carousel can get sticky, preventing the turntable from properly moving. If you have built-on food particles or liquids, fill a bowl with 2 or 3 cups of water and 1 tsp. of liquid detergent and lemon. Run the microwave for about 3 minutes. Clean the microwave with a cloth, including the base of the turntable, guide, carousel grooves and microwave base. Your microwave turntable won't rotate if the grooves on the base of the turntable do not sit right on the carousel. Also, check the position of the turntable guide. Place the guide directly under the turntable. Remove the turntable, and then reposition it into the carousel grooves.
Motor The carousel motor is located beneath the base plate of the microwave. If the carousel isn't turning at all, check the motor. Disconnect the microwave from the power source, and remove the turntable, guide and base plate. Try turning the motor to see if it's just stuck. If it doesn't turn freely after a few seconds, examine the motor to see if it's burned out or corroded. Use an ohmmeter to see if the motor has continuity. If not, you must replace the motor.
Bushings The drive bushings are plastic components that sit underneath the cooking plate. Remove the plate, and examine the bushings. Use a magnifying glass if necessary to see if any debris is caught in the plastic. Clean the bushings, and reinsert the plate. Turn the microwave on to see if it rotates. If the bushings are extremely worn or if some of the plastic is broken off, you need to replace it, which is a complicated repair for consumers. Contact a service technician for assistance.

GE microwave oven squeals as carousel is rotating. Noise stops in a minute or so but begins anew when the unit is used again.


If it is the wheel on the turntable that squeels, wash the turntable in strong solution of washing up liquid and water.
If it does it without a turntable fitted, change the turntable motor.

Replacing the turntable motor.

The motor assembly is fixed to the base of the oven usually with two screws and access i obtained by removing the inspection plate directly beneath the motor. It is usally a plug in synchronus motor that revolves at a few revs per minute but the plastic cogs in the motors gear box fail and the motor assembly must be replaced. They are fairly inexpensive and obtainable usually from a domestic appliance repair shop.
If you feel confident, disconnect it from the mains power, remove anything in the cavity and turn it upside down if it is a tabletop model, a little more complicated if it is built in!
Remove the inspection plate and disconnect the motor. Remove the motor and go and get a new one. Re fit it and put the microwave back in its position. Plug it back in, with the turntable and plate. Put a cup of water on the plate inside of the oven and heat for 20 seconds to check the plate goes round.
Hope this helps.

The sparking is usually due to accumulated grease or food particles.

If there is any chipping, charring or rust, it will have to be sanded smooth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Sparking is most likely to occur when cooking small items or low-moisture foods like popcorn.

I always recommend that folks put food off-center on the turntable to assure more even heating and to protect the turntable glass.
