Microwave buzzing and flapping noise on windy days

On windy days (moderate to high) depending on which direction the wind blows, my Spacemaker XL1800 JVM1870SK04 has either a flapping or buzzing noise coming from the microwave. Very irritating, quick fix is to turn on the vent fan and no flapping or buzzing sound.
This noise can only be heard from inside my house, I have checked the outside vent flap which may be an issue causing air to blow into the vent (vent flap slightly open), but vent flap does not hit so violently when its windy.
What may be the problem? Is it a venting issue?

    I would first suspect a vent / duct issue

    It may be a partial blockage (most commonly an animal nest or leaves, etc.) which allows a sort of resonant or vibrating effect to take place.

    If you or a neighbor have a leaf blower, you could listen in the kitchen while a helper blows across the outside vent opening from several different angles.

    You may also need to remove the outer vent cap to inspect the duct. A duct cleaning brush will be good to clean it out, or a fridge coil brush will do shallow cleaning.

    You might also check your setup against the installation instructions.

    If
    for some reason you don't have yours, you can download
    the installation instructions here.

    There is also a buzzing that can occur on the control boards from these JVM18xx models, but ti will not be dependent on the wind. It is caused by a bad capacitor on the board. We have repaired quite a few of these for that.

    Please let us know how it goes, and we'll be happy to help further.

It's probably a bad turntable motor or coupler.

SOURCE: cold air from outside coming in house through vent

Sounds like your damper (flap) outside is working, and that's probably the first thing to check. Wind may be also pulling the damper open from time to time. Hopefully the pipe fitting is sealed, and the pipe is insulated anywhere it runs through any unheated portion of the house. Some amount of cold air getting in will be unavoidable. The best bet next might be to look over the two pages in the installation instructions that deal with outside venting. If you don't have the installation instructions, you can get a copy here: http://www.geappliances.com/service_and_support/literature/ Then if you don't notice any obvious problems with the installation, it may be time to contact the installer for their two cents.

SOURCE: Outside venting GE Profile Spacemaker XL1800

Your vent flap could be taped or it could be faulty installation not allowing the vent to open. If you take the front vent cover off, you should be able to reach in above the fan unit and gently push the vent flap up, it should move freely with no binding. If it doesn't it is taped or blocked. If it is taped, gently putting upward pressure on the flap might release the tape. If that doesn't work the vent installation is blocking the flap. You might have to remove the unit from the wall (two people to do this) or disassemble the vent duct above the microwave and rework the interface for clearance.

hope this helps,

SOURCE: Mouse in vent fan?

Yes, the mouse was probably attracted to the warmth and food odors in the duct work and may have gotten trapped in the vanes of the fan and died. I'd act fast...

The best bet is to remove the oven from the wall, or almost from the wall, so you can see the area of the hood vent exhaust fan.

This is safer with two people and the installation instructions will be of great help.

SOURCE: My Ge SpaceMaker XL1800 Microwave Oven won't power on any more.

1.Check power outlet for working.
2.If it is than you have broken fuse inside the m/w.
3. To change the fuse you have to disconnect the power to m/w, take the upper grill off, take the screw on top of control panel, lift the control panel up and removed. The 20 Am fuse located behind this panel.

GE Profile Spacemaker XL1800 The microwave runs, the lights come on, timers goes, but it does not heat/cook and it makes a loud buzzing sound.What is wrong with it,and can I repair or trouble shoot it?


Hi


Thanks for using FixYa. If it’s a loud hum/buzz sound then 90% it’s usually a bad magnetron and other times it’s a bad high voltage diode. However, from what you have described it seems to be the magnetron. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

GE Spacemaker XL1800(JVM1850CF001) - Loud Humming noise


You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

G.E. Spacemaker XL1800- Loud constant buzzing noise. Help


My microwave was totally dead. Things I discovered: 1) There is an easily replacable fuse accessed by taking off the top front vent cover (two screws on top, gently massage off) and then the inside plastic grill. UNPLUG before doing this! 2) Pop off two wires on either end of fuse holder for safety. Then pop out fuse and replace. For more extensive help, there is an evelope with a wiring diagram inside the case on the inside wall! Very helpful when diagnosing the surface lamp problem (I forgot to plug the ballast back in when I closed up the bottom).

Buzzing noise, wont work???


The magnatron is shorting, overloading the high voltage transformer. From the picture this looks like an older unit and is probably not worth a magnatron replacement.
