Closer or Doorset? The Open-vs-Closed Resistance Test

Closer or Doorset? The Open-vs-Closed Resistance Test Related diagnostic: Why More Closer Power Is Not Always the Answer explores the connected fault pattern and helps compare the evidence before choosing a repair. A door that feels heavy can be reacting to the closer, the doorset or both. Compare resistance during the swing with resistance near final closure. What the pattern is telling you The closer is involved throughout the movement, but the latch, keep, seals, frame contact and floor relationship become increasingly important near closure. A sharp late-stage increase changes what should be inspected next. 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. Closer power is an input into the system; it does not automatically remove resistance…
