Question about Microwave Ovens

1 Answer

I have a LG Microwave oven, model #MV-154SJ. When pressing Time Cook, the Microwave no longer heats. The light comes on like it would start heating but the usual humming sound is no longer there and the turntable no longer turns. It's like I would only put the timer on and not the time for cooking. Checked the breaker, checked the door, but everything seems to be fine. Read the manual but it does not talk about fuses. Please help.

This is usually caused by either a bad door switch, a loose door switch mount, or a sometimes problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

Not heating


Hello


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

Microwave runs but does not heat or cook food



If a Goldstar, LG or Zenith MV1610 or MV1608 is running but not seeming to heat a load placed in center of turntable, its probably because the "stirrer" intended to spread microwaves generated by the magnetron around the cook chamber is stuck so that most all the heating is directed toward the back and top rather than the center of the cook chamber. This usually occurs after cooking for longer than a minute with no load in the cook chamber - as when a model w/o a timer (such as a MV1608) is intentionally operated in cook mode to serve as a kitchen timer, or when a model with a timer function (such a MV1610) is accidentally operated for longer than a minute w/o any load. Before assuming the magnetron (usually warranted for 5, 8 or even 10 years) or other high voltage component such as diode or capacitor needs to be replaced, try “cooking” a 16 oz pyrex cup of water at full power on the outer edge of the turntable for 2-3 minutes - which usually reactivates the "stirrer" and restores normal cooking function.

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.

It's one or more of the following items -

Fuse
Diode
Capacitor
Transformer
Magnetron

Yes, you can fix the unit, and I can give you direction, but make sure the microwave circuit is not covered under a longer term warranty.
