Sorry, I can't take credit for the pics, they are from the DIY section. Now I have a question....will I hear anything if I didn't set the filter in right?

In the instructions it says the following:
The microfilter sits on top of the two black plastic tabs, not behind them.
• The ledge on the back side of the microfilter cover panel slides below the microfilter.

NOTE: If the microfilter is improperly installed, the ledge on the back side of the microfilter cover panel pushes directly into the microfilter, causing distortion. A distorted microfilter may interfere with the recirculation door.
