Only two screws to remove, then the sensor wires were detached by pulling them off-good idea to tape the wires to the edge- they will fall into the bottom of the drier and will require a long tool to extract. I removed the lint screen door and support and vacuumed and cleaned the parts and the resulting vent opening before reassembling. The hardest part was removing the sensors from the grille- the tabs holding them in place could not be flattened enough to pull them through the slots. Maybe I could have gotten them out eventually, but I took a short cut and hacksawed the plastic until I could break enough to remove them. It was a minor challenge to put everything back; first, reconnect the sensor wires then line up all the parts and replace the screws(they tend to slide around in their recesses and it takes some effort to get them back through the holes. But once back together, everything worked without any additional issues. Whole thing took about an hour.
