The centre pop bumper does not fire when hit and gives no points.
Centre pop bumper does nothing and doesn't score: spoon switch gap too wide
Cause: The switch blades under the pop bumper (worked by the skirt pin pressing a plastic spoon) were too far apart, so the switch never closed.
Checks
- If the bumper does not score, look at the switch; if it scores but does not fire, look at the coil and its voltage.
- Under the playfield, press the skirt down and watch whether the pin flexes the spoon enough to close the contacts.
- Look for a worn spoon with a hole in its cup.
Fix
- Clean the contacts and close the gap so a light touch on the skirt closes the switch; replace a worn spoon.
