    On my LTM9020W microwave, I unplugged it to clean behind it and then cleaned surface. When I plugged it back it, it would not work, then the next day, several buttons worked, now the clock, dinner plate, 3, 9 and the start button on the toaster does not work?

The Main Board error codes indicate for most of occurrences that the board itself has not passed the start up checks that are built in but there are cases when this is due to peripheral like door safety switches, shorted elements etc. While it is quite worth to explore this yourself if you are a techie and feel confident, please do not attempt if you do not know for sure what you are doing. And yes- DISCONNECT THE POWER PLUG BEFORE YOU ATTEMPT TO REMOVE COVERS and keep it disconnected till the work is over.

Check care fully for the looseness in all the connectors that go to the main board behind operating panel and the door switches, thermal cutouts and magnetron itself. you need not to know about these components, you are just looking for loose connections. If you find any - try to unseat and then seat them firmly. This alone will solve more than 50% problems. Pay attention to the green flat ribbon like cable that comes from inside of operating panel and goes in on large blue socket of main board. You need to pull a blue long tab on the socket itself away from board before you can disconnect the cable, and push it back after cleaning side surface of cable and putting it back in previous place. If this cable is loose, some or all buttons of panel will not work.

There are instances of complaint that the microwave platter starts rotating with or without the sound of internal cooling fan when door is opened - in 99% cases it is upper door switch - it's actuator - dark brown tab which comes out when the door is opened is failing to come out fully. You may attempt to set it right yourself if you are a good hand in repairing small components or obtaining exact replacement is not difficult from repair shops. Its technical name is micro- switch and you either will need to tell the size and no of wires coming out of it or the best is to remove the same and show it in the shop to get exact replacement. In my case the internal leaf spring needed stiffening and it worked fine. Similarly other door switched also cause unexpected things but usually it is small problem.

Although if you leave power plug connected and power on during nights, and fine one fine midnight that the appliance is making sound, usually it does not mean the microwaves are working inside. It could be opposite of the thing described above. But - why to leave it on during nights? Best practice is to unplug it when not in use. This will certainly protect your appliance from voltage surges that are known to damage electronic appliances often.

One reader quoted non functioning of panel switches when a through wet cleanup was attempted- It is nothing but some how water or soap solution got inside the layers of panel switches which happens to be membrane type. Some switches may start functioning (usually the upper ones when water moves downwards due to gravity) after some time . The best possible safe solution would be to remove water by gently using a hair dryer on outer surface to heat it up so that the water in internal layers evaporates slowly bringing all buttons to previous level of functioning. Take care not to heat-up too much or the plastic panel may deform - use a 6 inch distance at medium heat setting and your patience. It might take a while but half an hour work is worth against replacement. If you are more confident- you may attempt to peel off delicate layers of switch board, clean them and reassemble back using thin double sided tape. Mind that even though you are not removing cover, appliance is to be disconnected from mains first.

Hope it helps.

Dear Sufferers
I also belong to this club. This is a very common company policy that the CPU-s are programmed such that it will stop functioning after about 11/2 years and disply E10. By then the co. will anounce that the model is obsolate and no spares are available. The user is compelled to buy a new one. This is just a forced sell tecnick.So guys face the music.

Error code E10 usually means a defective control circuit board. I would recommend contacting LG India to have them refer you to a local LG-authorized service center. If you want to buy and replace the boared yourself you can ask LG India where to buy parts. LG India is at

SOURCE: LG 1925 Microwave suddenly stopped cooking, other functions work fine!

What you said about the the clock leads me to suggest that you first unplug it for a few minutes then plug it back in. It may just need a good reset. If you don't have your owner's manual you can download one here: The mention of odor concerns me. It may just be a bit of food or grease on the waveguide cover, which is a small sheet or panel on the wall or ceiling of the cooking cavity, but it may indicate the failure of a part in the high voltage section. You may have an intermittent door switch. You can see some of my other responses for info on how to get our important text file that helps you diagnose and repair door switches and gives important safety tips.

F3 code on lg microwave oven after power outage

The Electronics panel can be replaced. It is highly likely that the rest of the parts still function ok.
But NOT BY YOU unless you are a qualified person to carry that out!

Microwave oven voltages are LETHAL ! Touch the wrong place while live with the power on, by accident, and it will be goodbye.

You can find a second hand working one on for a reasonable price.
