Lg 700 w microwave everything is working as normal but the food is not heating up


There three parts that will cause this, the first is the magnetron "heats food" the most expensive part, followed by the high voltage capacitor and diode, they work in conjunction to generate the high voltage to cook the food.

Microwave model MV-1510M is not heating, also sounds louder. Everything else is working, fan, lights, turntable etc..


If everything is working normally, except for heating, the likely cause is the magnetron.  Microwaves can be dangerous to work on, as the site below points out.  If you have an ohmmeter, it is possible to check the magnetron, but be certain to follow the precautions outlined at the webpage:

Everything works ok except strange hum and no heat


When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.
If it is under warranty you are golden. If not, you should get an estimate, as many new microwaves are now in the 50 dollar to 99 dollar range

Check the fuse between the highvoltage terminal of the transformer and the hivoltage capacitor. If it is Ok replace the magnetron.

Lg LMV1630st stainless steel microwave oven


I'm confused. If it's 6 weeks old, you can get it repaired free.

If it's 1-1/2 years old, the manufacturer will cover the part cost of the magnetron (assuming that's what's wrong) and you will have to pay for labor and any other needed parts.

Also, the subject line mentions a model LMV1630ST while your message body mentions model LMV1680BB.

For Goldstar / LG / customer service, help, call 1-800-243-0000 (M-F, 7am-8pm CT, Sat 8-5 CT) and choose the appropriate prompt from the menu or visit here.

Chances are your problem is a bad magnetron, but it may be another high voltage part.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

Goldstar NV1502 No Heat


You should still have about a 5-year warranty on the magnetron, if that's the trouble.

If everything else works, it's almost certainly a high voltage component, most likely the magnetron or diode, but also possibly the transformer.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

I would contact LG / Goldstar first. For Goldstar / LG / L.G. help, call 1-800-243-0000 (M-F, 7am-8pm CT, Sat 8-5 CT) and choose the appropriate prompt from the menu or visit http://www.lgservice.com.
