microwave door stuck....wont open
The reason the door would not open upon pressing the door opener is because the BRCKT-LATCH was broken. I discovered that after opening the microwave enclosing. The BRCKT-LATCH has two ends sticking out....each fits into a hole. One of the ends on the LATCH was broken and therefore it was not tightly fit. No upon pushing the door opener the LATCH would not function properly since it was loosely fit and hence the door would not open.
To Fix this issue:
1) Buy a new BRCKT-LATCH
2) Remove the microwave enclosing. I had to use a special screwdriver, since the screws were security protected on my microwave. After removing the case, I opened the door by manually pressing the door latch upwards (please make sure that the microwave is not connected to the electric socket before removing the enclosing).
3) pull out the old LATCH from the microwave.
4) carefully insert the new LATCH. Try not to put too much pressure when trying to fit the latch, or else the ends may snap again!!
5) Close the door and try opening it by pressing the door opener. it should work now!!

Microwave worked intermittently depending on how door was closed
Remove top grille (2 screws), undo control panel (1 screw). Tilt down control panel, switches are on the left. There are actually three switches that are involved with the door, two horizontally mounted, one vertically mounted. This would be an EASY REPAIR, but it took me a while to figure out which of the three switches was bad, and also took a while to figure out that there is a plastic rod that inserts through the hole in the switch body. Once i figured this out went like a breeze. Lower horizontal switch was the bad one, but since the kit came with two switches i went ahead and replaced the upper horizontal one as well. IT appears that the horizontal switches are probably more likely to fail than the vertical switch based on the position of the switch and force angles. Works great now!

loud buzzing noise
The repair went well...I am so glad that I read this info before buying a new microwave....it saved me lots of money. I did have a repair man come and look at it and he told me to buy a new one but it cost alot of money when it wasn't necessary. I did the repair and I was very proud of myself.
Three men watched a woman fix this and it was no problem...they were impressed also....
