  If your Raynor Door Opening System door doesn't respond to the “Open” command but responds to the “Close” command, the issue might be a defective “Open” push-button or “Open” limit switch, which would need to be replaced. Another possibility is a loose wire on the “Open” push-button or “Open” limit switch, so verify and correct the wiring.

  Logan DavisAug 26, 2025
  If your Raynor Door Opening System door only closes when you're constantly applying pressure, it could be due to a few reasons: * Check if the selector switch is set to C2 mode; if so, switch it to B2 mode (B2=1). * Make sure the photo cells are properly aligned and not obstructed. Clear any obstructions or realign them if necessary. * Inspect for faulty monitored photo cells or loose wires, and verify, tighten, or replace them as needed. * Ensure the reversing device is connected with monitored photo cells as per UL325 for momentary contact to close. * Check for any obstructions in the loop, such as metal, and clear them.

  If the “Stop” button on your Raynor Door Opening System isn’t stopping the door, it might be because you have two or more 3-push button stations connected in parallel. To fix this, verify and correct the wiring, ensuring stop buttons are in series, and only open and close buttons are in parallel.

  Emily JonesSep 1, 2025
  If the Raynor Door Opening System motor turns but the door doesn't move, it could be due to a missing sprocket key, a broken drive chain, or a slipping clutch. Replace the sprocket key or the drive chain if either is the issue. If the clutch is slipping, adjust it to the proper tension.

Why does Raynor Door Opening System door reverse to fully open position?
- J
  Jessica HooverSep 4, 2025
  If your Raynor Door Opening System door reverses to the fully open position after closing and reaching the floor, it could be because the “Close” limit switch is not being engaged by the traveling cam. The close limit switch needs to be adjusted properly at the end of travel. Alternatively, an “Open” command might be given, so verify the “Open” push-button or any opening device for a short-circuit.

Why don't Raynor Door Opening System limit switches hold their settings?
- J
  Jordan LevySep 9, 2025
  If the limit switches on your Raynor Door Opening System do not hold their settings, it could be due to a loose drive or limit chain, which needs to be adjusted to the proper tension. Also, ensure that the limit cam retaining bracket is engaging in the slots of both limit cams. Check if the limit cams are binding on the shaft threads; if so, lubricate the shaft threads so the limit cams turn freely. Finally, verify and adjust if the limit shaft has a slight “play”.
