Hello,

I will advice you verify if the hot surface igniter is coming on when the oven thermostat is in demand. When the thermostat is turned on for the oven you should see the igniter start to glow. You may need to remove the bottom oven panel to be able to see it in action. If it starts to glow then take a wrench and tap the gas control valve located at the back of the oven in the broiler/storage compartment on the bottom of the range. If you tap the valve and the burner comes on then shut off the oven completely and back on several times and make sure it is working. If it does you may have solved the problem. If the burner does not come back on and you have to tap it again then the gas valve is sticking either due to a bad valve or weak igniter. If the igniter does not glow then the igniter could be bad. You would need to verify the igniter is getting voltage. Then the igniter can be tested with a ohm meter. A good reading usually is between 500 to 700 ohms. The hot surface igniter cang get a crack in it causing it to stop working.

Take care.

Sounds like the high-voltage magnetron (the heating unit) is not getting power. It could be as simple as a broken wire inside the unit (which would explain the spark) or a failed control board or high-voltage power supply (which also might let go with a spark).

Model MH7130xez won't heat. everything else works. the clock, timer and lights. does this model have a fuse?


if unit won't heat, then there is a problem with either the magnetron or the diode. if its the magnetron, the microwave will sound almost normal. if its the diode, it will make a humming sound

Microwave not heating


OK, if everything, including the fan, is working, this will confirm Magnetron failuer. you cannot reset the function of a failed Magnetron heating unit. replace this failed device asap if possible.

Does not cook - time counts down extremely fast


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 about 5 minutes.

Then let us know if the hard reset does not fix it.
and please reply back with your brand and model number so we can help you.

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.
