🚪 Door Closer Issues – Spotting a Defective Closer
It’s easy to tell when a door closer is failing:
-
Oil leak: You may notice oil marks underneath the closer.
-
Door slamming: The door may start slamming if the oil drains completely, which could even break nearby windows.
-
Unable to adjust speed: If the door won’t adjust to normal closing speed, the closer is likely defective.
