    There was no manual there. I could not solve the problem so i replaced the unit, unfortunately the micrwave was disposed of so I can't further trouble shoot it. Thanks for the assistance.

    COM03? Not sure what that is.

    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 & testing.

    You should do a continuity test on
    the fuse while it's in the holder (with the microwave unplugged, of
    course) then turn the fuse by hand or take it out and put it back in,
    then test it again.

    If you remove the fuse, then press the meter
    leads against the ends, it can allow internal contact to be made and
    make a bad fuse appear to be good.

    the fuse is good, it may be an open thermostat or thermal cutout (TCO)
    / thermal fuse on or near the magnetron or on top of the cavity / body
    of the oven.

    Let me know what you find.

SOURCE: Hi I have a GE JVM1533WD 002 spacemaker microwave

It was the upper thermostat. I switched with a identical one below to get results, Magnetron seems to be burnt out as well.

SOURCE: Unit has power - program to heat - cavity light

This appears to be a classic magnetron failure, the magnetron has failed and most likely the high voltage diode as well, BOTH of these items will have to be replaced, also check the PSU out too, there maybe a bad diode there too..
BE CAREFUL Always discharge the BIG Capacitor to earth, with an insulated shorting stick, each and every time you turn it ON...& OFF. MW's are LETHAL...

I have a samsung microwave that my daughter ran 20 min. empty. now nothing works. it acts like there is no power, but have checked my breakers and tried various plus. stiill nothing. what does the fuse or...


the problem of this unit is power related.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. It may cool by then and might power on. If it doesn't power on, plug it into another outlet, to make sure there electricity entering into the unit.

If plugging into another power outlet doesn't power it on then the unit is most likely having a power problem.

When electric current comes from the power outlet into the cooker, it goes straight into the power supply board which then circulates the current into the unit. So if the cooker doesn't power on, the first thing is to make sure there is power entering into the machine.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

If any machine or electronics device doesn't power on, it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Best wishes.

Model #PLMV169DCD Power stopped..source checked and is fine Is there an internal reset?

Almost all microwaves are internally fused (automotive style fuse with a ceramic case). They are only a couple of dollars at an appliance parts store get one with the same amp/volt rating which is stamped on the metal band at each end of the fuse. However, if the fuse blows repeatedly, it is a sign of a failing magnetron "tube" which cooks the food. Be sure to unplug unit before changing this fuse and avoid contact with the capacitor(s) inside. They can still hold a charge even when unit is unplugged.

No power and I replaced fuses in microwave.

Have you checked to make sure that you have power coming in to the unit? Check the fuse to the outlet that the unit is connected to before we go any further.

Ok , I replaced the fuse checked all connections and checked plug for power ! Still my lg lmv1630st will not show any power at all . What gives?

by replacing the fuse you meant the house circuit fuse or the microwaves internal fuse? and by conncetions your talking the internal wiring inside the case of the unit or wiring from the plug? if not its your 15 or 20 amp ceramic fuse inside the unit,if thats blown replace,but chk h.v.diode,v.v. cap,triac,control board, mis-adjusted interlock safety door switch,and lastly the mag could be defective

No power to microwave, changed fuse but still nothing!

There is an internal fuse and internal TCOs (thermal cutouts / thermostats) any of which can interrupt the power to the unit.

Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

You can remove the grill on top; there should be screws on the top of the microwave and/or within the grill itself. Then remove the control panel, should be one screw on the top of the panel, then lift up on the panel and tilt it out. The fuses should be visible from there. If the fuse is the problem it's easy to change, just remember to unplug the unit first before working on it. And I would suggest getting a single outlet surge protector for the unit; microwaves are very sensitive to power spikes. Please contact me if you need any more help.

No power

You mentioned taking the "buttons" off. That may not give you complete access to the units motherboard or power supply area. Unplug the unit and remove the outside cover. Look for a blown fuse on the motherboard or power supply. Replace it with the EXACT value of the original fuse. You can purchase a new fuse at Radio Shack or hardware store or auto parts store. Try powering up the unit again and see if it works now or whether the fuse blows again. If it blows again, the power supply may have been damaged.
