Commercial Door Closer Troubleshooting

Door Closer Not Closing? Common Causes and Fixes

When a door stops latching, security and operation can be affected, and a rated opening may require inspection review. Start by documenting the symptoms before deciding on adjustment or replacement.

Possible Causes

  • Improper sweep/latch speed settings after ad-hoc adjustment.
  • Hydraulic closer body leaking oil and losing control pressure.
  • Door or frame misalignment causing drag near the strike.
  • Worn hinges changing closing geometry.
  • Incorrect closer size for door weight and traffic level.

FAQ

Can adjustment fix a door that slams?

Adjustment may help when the closer is serviceable and the opening alignment is stable; diagnosis is needed before deciding.

What if the closer is leaking oil?

Leaking often indicates replacement is the reliable long-term solution.

Do you service after-hours closer failures?

Yes. Call to confirm emergency and after-hours availability.

Do you support fire-rated openings?

Call to confirm whether the rated-opening scope and required qualifications can be supported. Final inspection acceptance and compliance determinations remain separate.
