Why More Closer Power Is Not Always the Answer Related diagnostic: Closer or Doorset? The Open-vs-Closed Resistance Test explores the connected fault pattern and helps compare the evidence before choosing a repair. More closing force can overcome resistance without removing its cause. A door that closes after a power increase may still have the underlying fault. What the pattern is telling you Inspect latch/keep, hinges, seals, frame and bottom interface first, then review adjustment history. Increased force can also leave secondary evidence around hardware and wall junctions. For closer faults I would record exactly when and where resistance or interference appears. Check the arm, shoe, body mounting, hinges, seals, latch/keep, frame and bottom interface before changing hydraulic settings.
