20 Most Recent LG LMV1925 Microwave Oven Questions & Answers

Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.

Microwave Oven Basic Troubleshooting Tips

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: http://www.lge.com/support/manual.jsp 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.

Well .. I would first unplug it . .then turn on the breaker .. then plug it back in and see

The part number you need is 6912W1Z004B. You can this part at repairclinic.com for about $4 each. I hope this helps you.

Hi I've been out of the microwave repair business for a few years now, but the technology has remained virtually the same as far as I know. You obviously have some knowledge of them, as you know about the safety switches in the door. Microwave ovens are actually a very simple device, to test it, put a coffee cup of water inside, and set the unit on high for one minute. A second or two after you hit the start button, you should hear a fairly loud "bong" noise, and a hum that continues untill the time runs out. That noise is the magnetron starting up, and if that noise does not happen, then the magnetron or related circuitry is probably bad. NEVER open up the oven, as the magnetron may be charged, and must be discharged by a technician. If the sounds that I described are present, then the water should be boiling or close to it in one minute, if not,then something I've never seen has gone wrong. Assuming you had a year warranty on it, I know from experience that if you contact Goldstar customer service by phone, or letter, they will often extend their warranty a month or so to keep happy customers. Its worth a try. Hope this helps you out. P.S. Never operate a microwave without something inside (Non metalic)

If your LG Solardome microwave oven is overheating a melamine plate within 30 seconds, there could be a few potential issues at play:

1. Power Settings: Check to see if the power settings on your microwave are too high. If it's set to a high power level, it can cause certain materials, like melamine, to overheat quickly. Try reducing the power level and see if that helps.
2. Plate Material: Melamine plates are not suitable for use in microwave ovens as they can overheat and potentially release harmful chemicals into your food. It's recommended to use microwave-safe dishes made of glass, ceramic, or microwave-safe plastic.
3. Microwave Performance: If the microwave is consistently overheating items within such a short time frame, it might indicate a malfunction. In this case, it's best to contact LG customer support or a certified technician to inspect and repair the microwave.
4. Placement and Usage: Ensure that the plate is placed centrally on the turntable and not touching the sides of the microwave. Also, avoid using the microwave for extended periods without interruption, as this can cause overheating.
5. Testing with Different Materials: Try using a microwave-safe ceramic or glass plate to see if the issue persists. If other materials heat up quickly as well, it could indicate a problem with the microwave itself.

I have a new Kitchen Aid Convection Microwave with air fryer. I've not yet used the air fryer, but today I put a pan with a roast and set to convection roast and turned it on. I put the aluminum foil over the top of the pan and it sparked. I don't know why this happened. I'd sure like someone to let me know.

Remove the contaminated and fit a new Waveguide cover.

Here are the steps to remove the door cover from the door of your LG Microwave model LMHM2017ST:

1. Unplug the microwave from the power source.
2. Open the microwave door and locate the four screws on the inner edge of the door.
3. Use a Phillips screwdriver to remove the four screws.
4. Carefully separate the outer door panel from the inner door panel.
5. You will now see the door cover attached to the outer door panel.
6. Use a flathead screwdriver or plastic pry tool to gently pry the door cover off of the outer door panel. Start at one corner and work your way around the edge.
7. Once the door cover is removed, you can replace it with the brushed silver cover from the new door.
8. To reassemble the door, simply snap the new cover onto the outer door panel and then reattach the outer door panel to the inner door panel using the four screws you removed earlier.

Make sure to be careful when removing the door cover, as it can be fragile and may break if handled roughly.

Question edited for clarity. It depends where you live? In the UK, the fuse is in the wall plug. In the US and other countries it _may_ be at the rear where the mains lead goes in. Sometimes they pull out, sometimes there is a small screw cap. If you are thinking of getting inside it, this Tip I wrote applies. https://www.fixya.com/support/r29874712-repairing_microwave_ovens ..

Question edited for clarity. Question moved from Building Materials to LG Microwave. Take into an LG Service centre for repair. They are sealed by security screws and are dangerous inside. You won't be able to get parts.. If it is a counter top microwave and cost $60, just buy a new one as they are a disposable item.

if smells like something then something is burning stop using answer about can it be fixed is unknown till diagnosed

latch/catch failure

THE HIGH VOLTAGE FUSE IS IN A PLASTIC EXTRUSION NEXT TO THE CAPACITOR AND DIODE. YOU CAN USE 3 OR 4 STRANDS OF THIN WIRE FROM MULTI STRAND 15A MAINS CABLE. SOLDER IT OVER THE BLOWN FUSE. I HAVE DONE THIS 100'S OF TIMES.
