LG LMVM1935SB Microwave won't heat anymore!

My LG LMVM1935SB microwave all of the sudden stopped heating up foods. I wasn't aware of this as the microwave was appearing to run normally, but when I opened the door to remove the food after the appropriate cooking time, it was still frozen. Is this something that can be fixed or is the microwave history now?!

    Yes, the inside light turns on, and the turntable comes on. No unusual noises at all. Appears to work fine, except it won't heat... Thank you SO much! :-)

    When you hit Start to cook, do the inside light and turntable come on?

    Any unusual noises? Is it louder or quieter than usual?

    These answers will help me judge whether it's in the high voltage
    section (magnetron, transformer, or diode) or the control section
    (door switch or control board relay or connection).

With these symptoms, I would suspect you have a bad magnetron.

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.

Some manufacturers will send you the magnetron to do it yourself. If nothing else, you can save about $75 by taking it to the shop yourself.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

MY MICROWAVE IS NOT HEATING


If the microwave is turned on and you can hear the fan working when you set the time you should make sure of those things:1. You have selected the proper programme. Some microwaves have a control desiged to use the programs on the buttons. if you want to you the buttons to set time you should select "microwave" or a similar button and then press the power level like "1", "2" or "80", "100" (being percentage) and then press the buttons for timing.2. If you have used it for a while and it suddenly stopped heating the food, than it could be that your magnetron (a spare part) has burned out. Have a specialist replace it, or just get a new microwave, the price difference won't be that great for standard issue microwaves.

Problem with the GE Spacemaker (JVM1640SJ) Microwave Oven GE Spacemaker XL1800 won't heat food anymore....It worked this morning, now won't heat. What should I do?


GE Will replace the magnetron for 9 years! Mine is a 2004 model with a one year warrently according to manual. HOWEVER they did say the magnatron was covered for nine years: call 888-239-6832. When I called they said thats all they get calls for and would send out in 3-5 days. NO CHARGE. I had to ask if there was coverage longer than a year on major parts and that's when they offered the info and I eventually was transferred to the right office. Saved $120 bucks on parts alone.

Hi,
There is a device in your microwave oven called a magnatron. This device generates the microwaves which heats up the food. If all is working but there is no heat, it means the magnatron is faulty or perhaps part of the magnatron circuitry. Check all fuses and then have the magnatron tested by a qualified technician if all fuses are okay.
Please let me know if this has helped solve your problem.
Best wishes,
