SOURCE: I cannot start my microwave because when I press

OK, this Microwave has got a failed magnetron, and/or a High power Diode has gone faulty. You need to get it repaired by a professional, Always ask for a "Quote" because often, replacement parts, and labor, can often exceed or equal the cost of a new one, these days. Self repair of Microwaves is very dangerous, as there is nearly always lethal Voltages and Currents, even with an OFF, and Disconnected Microwaves, you see, inside, there is a GIANT Capacitor, this capacitor, feeds off the Magnetron,it can hold, for some considerable amount of time, enough Joules of energy, to kill anyone that touches it. Before any work is done, the first thing that must be done is to, by using and earthed "Shorting Bar" and touch it to each terminal of the capacitor to discharge it, There will be a BIG Spark, and a Bang, as the energy discharges. Once that is done, then they are safe to work,on, but if ever turned on again, say to test, then, it must again, it be shorted out. (This is where some service people come unstuck, they forget, after discharging once, that, after they had tuned it on, say to test, and then off again, that the capacitor, had immediately "Charged Up", just waiting....) Just as an extra, more service people are killed each year from Microwaves than any other single thing.

SOURCE: My lg ms3949cs microwave tripping the breaker when I press start button but was working before.Please help

Anything added to the circuit the microwave is on? Circuit could be overloaded.

You could have a shorted high voltage rectifier, high voltage capacitor, or shorted magnetron. Usually a door switch problem blows the internal fuse in the oven, but door switches should be checked anyway.

Can this be fixed by me?

Could be a bad door switch or a bad relay. With the door closed try gently pushing it up and down if at some point the unit fires up, one of the door switches is not making contact. As for the relays they are on the circuit board, but not replaceable unless you are very good at De-soldering. Also keep in mind microwave units have very high very deadly voltages stored in the capacitors 4000V that can easily kill so don't mess with them unless you know what you are doing!

My start button isn't working....I can press the "popcorn" button and it will automatically turn itself on and cook whatever I have placed in the microwave, but nothing happens when I press the "start"...

If it will start automatically without using the 'start' button, the 'start' button must be bad. If the door sensing switch was bad, it wouldn't start at all. It needs a new keypad. The most common cause of a keypad failure is from spraying a cleaner on it instead of using a just barely damp cloth to clean it. The liquid can run down the front of the laminated keypad and get into the bottom and seep up into the lamination....

How do I fix the programmed buttons 1 - 5, they stopped working? We can only use the 6 and above numbers.

You must dismantle the circuit board and check if some grease vapours between touch buttons and the the circuit film. Clean with some wet soft cloth.

How to unlock digitals butons?

Hi there,

It sounds like you've activated the child-lock - this would disable all of the digital buttons.

To switch the child-lock OFF, simply press and hold the START button for about 4-5 seconds until "LOCKED" disappears from the display.

To switch the child-lock ON, press "STOP/CLEAR" button once, then press and hold the START button for about 4-5 seconds until "LOCKED" illiminates on the display.

If the buttons aren't working and "LOCKED" is not displayed, then you may have a defective touch control pad.

Hope this helps - please let me know if you need further assistance.

Regards,
BElectric

Hi. I pressed the 'quickstart' button on my micromat 900 w microwave and used it for 10 seconds. On pressing the 'door open' button, the display panel is showing '1' rather than the cooking time or the...

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

It may be a problem with a door switch or door switch mount.

Microwave quit working

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

It may also be the high-voltage rectifier diode.

If you or a friend decide to look into it, we have critical safety information and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Feel free to post your brand and model so we might be able to give me specific info.
