    I have a goldstar mv1501w and it makes noise,cycles on the different power level settings, but it won't cook. I put a sausage in it today and ran it on the auto reheat or something and it actually cooked after 3-4 minutes though not 40 seconds like normal.

    Microwave turns on but will not cook food.

    We just had the same problem today with the exact same brand and model #. I searched the internet hoping to see a recall or easy fix, but this makes me far to nervous to mess with, so we are going shopping for a new microwave now. I have only had my LG for like two years maybe a lil more, and am very disappointed. I will not be buying another LG product again.

How to change fuse for lg lrm1250W


Hello

Get beneath the LG microwave, and grasp it on the bottom at either end. Lift the microwave up slightly, and pull it out from the wall to remove it from the mounting plate.


Turn the microwave onto its face on a soft rug or blanket. Remove the screws from the back panel of the microwave, and slide the panel upward to take it off the unit.


Look for the three fuses in the LG microwave -- one at the lower-right corner, one in the upper-right corner and one in the top center. Check each of the fuses to see if any of them look dark in color; this indicates a burned-out fuse.


Remove the burned-out fuse by gripping it firmly and pulling it away from the wall of the microwave. Once the fuse is removed, press the new fuse into the same position in the microwave until it clicks into place.


Slide the back panel onto the microwave, and replace the screws. Lift the microwave into the space beneath the cabinet from which it was removed, holding it slightly higher than the mounting plate, and lower the microwave until it catches on the mounting plate.

Unit turns on, turntable turns, but nothing heats


Classic symptoms for failed door interlock safety switches, though it could be other trouble.

Remove the cover and check the operation of the little micro switches that operate when you close the door.

DONT TOUCH THE SILVER CAN - LETHAL.

If you regularly open the door while cooking, the contacts in these little switches become burned. When burned badly enough, they cannot make contact. When they cannot make contact, the mocrowave doesnt know the door is closed and will not turn on the magnatron resulting in no heat.

If you need more help, let me know.

Does not heat up


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Lrm1250w/01 lg microwave turns on and runs but will not get hot any ideas I have the very same problem. The microwave shot craps. I too searched the internet for a fix. I suggested the purchase of a new...


If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.If turntable is not running check also the door switch.

The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.

LG LMVM2055: Cooked itself?


First you will need to answer a few quick questions between yourselves.
  1. Do you have life insurance?
  2. Is it enough for the wife and kids to survive on
  3. Whats the number for 911
After you answer all these questions, then pick up the microwave, and take it for a long drive.
There are bits inside there that will happily kill you days after it has been turned off. (some even weeks)
For the cost of a replacement in this case, it's not worth it.
