After shopping all over town trying to find a new tray I discovered PartSelect.com, I called and ordered the tray and received it the next afternoon. It couldn't have gone smoother.
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!!
