Problem Comments
Door Will Not Hold Open Check if 9-volt alkaline battery is installed and battery cover is attached with both screws.
  1. Does red LED flash when "test" button is pushed and held? If yes, continue. If no, call Glynn-Johnson Technical Assistance at (888) 371-7331.
  2. Wait 15 seconds.
  • 4. Push and hold "reset" button for 2 seconds.
  • 5. Move door to desired hold open angle and see if hold open mechanism catches. If no, continue.
6. Does slide block inside channel travel completely
to end of the track when the door is fully open? If
not, adjust (shorten) the arm length. Note: The
slide block must travel to the end of the channel to
engage the latch mechanism.
7. If unit still will not hold open, call Glynn-Johnson Technical Assistance at (888) 371-7331.
Door Will Not Release When "Test"
Button Is Pushed
  1. Wait 15 seconds.
  2. Push and hold "test" button for 2 seconds.
  3. If unit does not release, make sure door is not hung up on frame or the floor and that the closer is working properly. If unit still does not release, call Glynn-Johnson Technical Assistance at (888) 371-7331.
Door Is Difficult To Release From Hold
Open Manually
  1. Adjust tension by turning hold open tension adjustment screw.
  2. Check to see if unit is securely attached to the door and frame. If the unit rocks on the frame, the release mechanism may bind up during manual release.
Door Will Not Shut Completely
  1. Check if adjustable arm rubs or contacts any part
    of the channel. If it does, the arm may be adjusted
    too long, the door bracket may be mounted too
    high, or the channel improperly located. Verify
    template dimensions.
Door Will Not Hold Open After
"Smoke Test" 		As long as smoke is in the detection chamber, the red LED will be flashing. Wait for all smoke to dissipate, then press "reset" button, wait 15 seconds, and try again.
