LG MS-3444DPS microwave - spins but doesnt heat

Hi,
After entering number's on keypad I hit 'Start' and there was a noise inside microwave "Fatt" (same like how capacitor explode).
Now microwave lights come on, also it spins, but does not heat up.

I checked the capacitor which looks ok (no leaking).
Device is out of warranty.
Could some one help me on this?
Thanks

Chances are you have shorted or blown high voltage rectifier diode.

Here is a link you or someone you know can use to test it, but please read the safety info:

    You mean you changed the diode without testing it?

    When you try to cook, does it sound louder or quieter than normal?

My still fairly new kenmore 1000 watt microwave appears to be operating fine but doesnt heat. What might be the problem?


When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

Post a new help request with the answers to these questions as well as the full model number from the tag on or in the unit.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

Have a LG micro wave model no ms-3444dps and is not heating


It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
Make sure the !!!!any capacitors are discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Model Goldstar MS-71tc. when I plug the microwave in it on and the table spins and light inside is on as though it is microwaving something. But there is no heat being generated.I put something in to try...


The problem is in the magnetron "more likely" or the high voltage transformer that drives the magnetron. The cost to repair will run high in either case and come down to a personal choice, but! in the long run cheaper to buy new than to repair.

I have LG MS-3444DPS Intellowave Microwave oven. Turntable has had intermittent high pitch squeal and also thumping noise as turn table turns. Turn table has also been very jerky since new. What is the fix...


If you were to take the turntable coaster out and wash it in hot washing up water paying attention to the wheel surfaces, I think that will fix your problem as I suspect the wheels are uneven with deposits stuck to at least one.
Hope this helps.

Keypad does not work after steam hits it


I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

If it does not dry out over time, it may need to be manually dried or blown out.

The keypad may be damaged or worn out, or control unit may be damaged.

Keypad failure can cause it to come on by itself, which can lead to a fire.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

LG microwave LMVM2075ST panel started acting crazy after I cleaned it. Will not do anything if I push a button except beeping noises. Any suggestions as to what is going on with this machine? Should I try...


liquid probably has entered keypad laminate; causing a short. unplug unit, direct warm hairdryer to entire keypad; plug back in; and hope for the best. if no luck; replace keypad. also never spray anything directly onto keypad; always clean with a moistened towel with light force.

Microwave stopped working when i pushed the start button


Yes. The white inside the glass that you are describing is a blown fuse. To find out what size fuse it is look around the base or top of the fuse. You will see engraved something like "125V 5A. You can pick these up at Home Depot or Lowes in the electrical isle. You can also type www.google.com and enter the word "fuse" and then the size it is. (125V 5A) If you have found this information at all helpfull, please rate my solution. Thanks D. Lange

Wont heat


Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.

I recommend checking all these area that are located inside the microwave for faults.

The most common issue will be a failed Magnetron.

The diode and, fuse will be located on the noise filter assembly.

MS-3444DPS LG Microwave


You can see and hear a YouTube video of how a turntable motor should sound when you rotate it by hand.

If yours won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven. You may have to cut the cover off with snips, then use a screw when reassembling it.

Microwave Keypad not working


This model does have a child lock. If it's on, the display will say "LOCKED". It is turned on and off by holding dfown the "0" key for 4-5 seconds. You may also have a bad keypad, which in many cases can be replaced. A bad keypad may be worn out due to age, damaged, or it may have gotten wet or otherwise contaminated. Moisture and contamination can be caused by spraying of cleaners, by storing the microwave in an unheated garage or shed, or infestation. I warn my customers to never spray cleaner directly onto the microwave keypad, since the liquid can get inside and "lock up" or even ruin the keypad or controller. Apply an alcohol-based cleaner (such as the purple kind) to a cloth (paper towels can scratch) and gently wipe it off. I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics. Repost if you need more help.
