Backcheck: How to Tell Deliberate Resistance From a Closing Fault 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. Backcheck should be treated as controlled closer behaviour, not a catch-all explanation for opening resistance. What the pattern is telling you Observe the point in the opening cycle where the feel changes and compare it with the closer instructions. Resistance present from the first movement may belong to hinges, seals or frame contact instead. 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 elsewhere. I would therefore separate the visible symptom…
