CPBM3077RFC Frigidaire Range - Instructions

First thing I dir was search YouTube for any related videos and found this one https://www.youtube.com/watch?v=uHj4H9Fdxrc, it was the exact problem my microwave was exhibiting. Once I verified the problem by troubleshooting, I removed the part and verified that the switches were working fine, the door latch assembly showed signs of wear which was the cause of the problem. After receiving the replacement part I installed it, verified that power was restored to the unit and reassembled the microwave, works fine, hope it lasts a long time!

You have to be very careful because the wave guide cover is very brittle. It needs to be bent very gently in order to fit the four ends into each slot. I would highly recommend buying two just in case the first one breaks.

I thought the cover was suppose to come off from the inside of microwave. It is brand new and got bent. So I ordered a new one in case it was not working with a bend in it.

made TWO (2) parts orders one (1) for latch, (1) for the Spring. Using a dinner knife I removed plastic cover on inside door to inspect the spring and latch. Found both to be in working order, where the spring attached at the lower plastic spring attachment area was broken. In other words I needed another door or Microwave unit, After exanining area I determined that a home fix was possable with 1/16 inch diam. piano wire by bending a tight loop at top and hooked to spring, then pulling down to put tention on spring enough to keep latch in proper possion, I then marked wire and cut it and bent it in a hook and hooked it to a metal fin like brace, operated door works well. TOO MANY PLASTIC PARTS.

Fived the tab in the appropriate slot and seated the plastic dowel on left side. Bent unit so bottom tabs fit into appropriate slots. Affixed screw in left side tab affixing unit to microwave on left side and affixed right screw .THE VENT BROKE FROM THE SAME TOP LEFT SLOT 4 DAYS AFTER FIXING. THE CURRENT VENT IS AFFIXED WITH 2 PIECES OF GORILLA TAPE TO THE MICROWAVE. SO FAR SO GOOD

I kept the ring and just placed the tray on the old ring. Works great.
