Sadly, we hear of this over and over.

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

Details covering some previous models are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit. The parts kit is similar to this one.

(Your model may use a different kit - this is shown for illustration purposes only).

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

They may send you a replacement magnetron. GE Customer Service is here.

I need an instruction manual


press both Hour and Min buttons simultaneously for two seconds. You will hear a beep and the timer will reset. Don't press any other buttons for twenty seconds. The display will now change from the time to the clock. Press the hour botton. The hour digit will blink. Use the Min button to set the hour. Once you have the right hour, press the Hour button again, and the minute digits will blink. Press the Min button to set the minutes. Once you have the correct time, press the hour button one last time and your time is now set.

My LG LMV1630ST has an issue with the clock. 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 about 5 minutes.

Is it a US model (made for 60HZ power) being used overseas
(50HZ power)?

The clock works & counts down but the microwave won't heat


  • Disconnect the power for 30 seconds. After restoring power, do not set the clock.
  • If your model has an ON/OFF clock display, you can choose not to have the time displayed. To choose this option, press the 0 pad for about three seconds. To Turn the display back on, press the 0 again.





Touch the clock pad. Enter in the correct time of day by touching the numbers in sequence. Touch the clock pad again.

Shuts off after maximum of 8 seconds. does heat when on.


Sounds like the controller board has failed, assuming a circuit breaker has not tripped or fuse has not blown.
If all you do is reset the clock, and then it looses time, regardless of using the microwave, then it points to the clock/controller board.
If this only happens when you use the microwave portion for a few seconds, I would be suspicious of the microwave circuit, where there are several components that could cause the failure.

Clock will not reset


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.

Your owner's manual will you tell you what the icons in the display mean.

Many Emerson microwave owner's manuals are available for free download here.

Even though yours may not be there, there might be one close enough to help you .

Once you've done a reset and checked your manual, if you still need help, let us know.
