Not familiar w/pancake switches. But switches go bad before cables.

My proxes have led's. However they should only be lit when over a 'target'. In my case these are metal washer-looking things that the prox senses and tells the machine:'okay to do your next move".

Do you have a spare switch so you can replace the one you suspect? If you swap it and no change, put the old one nack in and try the next thing.

There should be a green power lite on and an amber lite that comes on when it is sensing, if P4 comes on without seeing P3 first the machine will shut down it has to see the in order, What color are your switches? you can take the cable from P3 if its the quick connect and put it on P4 to see if P4 comes on it would not be the cable. P3 and P4 are on the pass side P3 is on enter side and P4 on exit side
