Micro Wave no heat all else fine. Also at times door would not shut properly.
Replace (after testing w/ohm meter) diode and locker holder. My door often would not close properly. Microwave let know by saying not shut properly. When disassembled found the top screw mount was hollowed out resulting in it moving on occasion when you close door. First remove casing (special safety torx head) needed for rear screws. Onc e removed all parts available to view or work on. Diode is on the capacitor so caution is needed when removing. Serious shock hazard if touched. Use insulated pliers to remove from capacitor and a phillips on the ground. Test with ohm meter Should have resistance on way and non the opposite. Replaced mine bad. Next the holder 2 phillips screws and its yours. Unplug each switch and remove. Take note to what wires go to what switch and what switch mounts where. Mine had 3 switches. Removed from old holder and put in new. Screwed holder back in place and left scrws loose till re wired. Once wired set the holder by lightly tighting the screws. Try the door till it seats properly ensuring that all 3 switches are working properly. If so thighten screws. If all seems to work as advertised, safely plug in and test unit if heats up un plug and put cover back on micro. Your all set. Happy heating.

Changing door switch
When removing a non-working door switch, you will see a hooked piece of plastic on the holder locker that looks like a latch. If you try to pull it back in order to either remove the bad switch or install a good one, it will likely break. Instead, you need to pivot the switch (It pivots on a little post which is fitted into a hole at the corner of the switch) out of position so that it is not held back by the 'latch'. Then lift the switch out. If you have to use lots of force anything, you're doing something wrong. Reverse all this when installing the new switch.

Holder bracket broken so Door swithch could not be activated
Part arrived next day! Thank you Parts Select. Holder bracket on older GE microwave was broken so MW would not start because door latch did not activate door switch. Removed front panel unplugged all the wiring (after I had taken a picture) to gain access to the holder bracket. Unplugged the three door switches. Removed two screws that held the holder bracket. Installed three new door switches into the new holder bracket. Positioned the bracket behind the frame and screwed back in the two screws. Snapped in this seven wire attachments, set the control panel back in the microwave and secured it with two screws. I only needed one screwdriver and one needle nose plier to remove the wire attachment from a door switch which made it easier to remove. 40 minutes.

I ordered my filter using the requested model #
Unfortunately the filter upgrade for my microwave was not a fit. When I tried it in my microwave my microwave did not work. I thought I was going to have to have a repairman come and check what was wrong. I decided to put the original filter back in and when I did my microwave worked fine. Select Parts Has issued me a refund for the purchase I made that did not work. I am at present still researching for a filter that work for my microwave.

The new part was too thick for the worn out plastic ring which is obsolete.
Needed to raise the part to match the ring. I used peanut butter to hold plastic shim while replacing to hold it in place. Built in Oct. 2009.

Microwave fan would come on when door open. Timer and unit would not switch on.
I looked up my problem on the internet and found a very helpful video. Microwave on video was different brand but the internals and methods were very much the same. The video made it simple and easy to fix. Found the replacement switch on the LG parts site and ordered. Two different switch types. One with red switch, the other green. Part was $7.28. Saved a bundle in service costs. Here is the repair video.

Items were not getting heated up in the microwave,
I went to LG website enter model number and was given a list of parts that need to be replaced with a percentage of which part fails the most. I order micro switch PS3522738 which arrived and PS3529293 was backordered. I installed the one that arrived. The microwave worked briefly. I reordered and waited for both switches to arrive and installed both. The microwave still doesn't work.
