01Stop before changing force or sensitivity
Keep the travel path clear and stop repeated operation. Do not raise force, defeat protection, pull the release on an unsafe or raised door, or move springs, cables, brackets, tracks, or supports to make the opener continue. If the door is crooked, partly raised, visibly damaged, or moving unpredictably, keep everyone away and arrange qualified service. This guide does not provide a balance test for a door that may already be unsafe.
02Record what changed without naming the cause
Note whether the refusal occurs while opening, closing, or at a particular position. Record recent impact, service, noise, power interruption, and any model-specific error display that can be read without entering the travel path. A refusal can involve the door, counterbalance system, opener, protection system, installation, or another condition. The observation does not identify which one, and increasing force can conceal the question rather than answer it.
03Ask for the door and opener to be assessed together
Give the technician the exact opener and door labels, position, event history, and any documented error. Ask how the door’s condition and balance were evaluated before any opener adjustment is proposed. DASMA’s guidance supports the principle that more opener power does not correct a door problem. It is general safety guidance, not a model-specific adjustment or inspection procedure.
Notice next: Leave force settings unchanged, prevent further operation when safety is uncertain, and request a door-and-opener assessment from a trained garage-door technician.
