Quoted from Damien:
So I pulled the pf up, and took a look. Seems the wheel wasn't pressing down on the switch enough to make contact. All I did was move it around with my hand a little, and it started making contact. Played a few games, and seems to be working, but I suspect this problem will reoccur. The part that looks like a leg leveller seem to only be able to adjust the diverter on top, but what adjustments could be made to ensure the switch always gets enough contact to press in that little green button? The rotating wheel doesn't seem to be adjustable, so it would maybe come down to pulling out that switch and attaching something thin on it that would close the gap that there seems to be between the wheel and the switch. Any thoughts on this?
I'm also now getting an error on coil #36, showing that the trap door is "broken".
You can bend the leaf switch blade that has the roller up just a little bit so it makes contact easier. You can also loosen the two screws on the switch then angle the switch upward and re-tighten. It shouldn't take much of either to get it to work reliably.
The trap door is probably the issue that's been discussed a number of times in this thread. Read back a few pages on how to fine-tune that device.
