  First, check that the power is on at the circuit breaker and disconnect switch, and verify all wiring connections. Then, check the fuse in the junction box. Also, ensure all connections in the J/box (near the operator) and control panel are secure; specifically, check that the ribbon cable to the LCD display is firmly connected at both ends. Check the voltage between terminal +24 and COM; if the voltage is less than 23V, inspect the wiring between the junction box and the control panel. If 24Vdc is detected and the ribbon cable is connected, the LCD panel assembly may need replacement. Finally, disconnect the +24V wire in the control panel and check the voltage; if it reads 24Vdc, the control panel circuit board may require replacement.

  First, ensure that the photo-eye/reflector/thru-beam sensor is properly aligned, not obstructed, and correctly wired. Clean, realign, and clear any obstructions. Recheck the wiring. If the issue persists, the force monitoring may be too sensitive; adjust the Closing Force setting in the Advanced Menu, noting that 1 is most sensitive and 20 is least sensitive. Also, there might be malfunctioning third-party reversing devices; disconnect them and install a jumper between reversing input terminal 3 and +24 to test. Reconnect the reversing devices one at a time to identify the defective device.

Why Richards-Wilcox DYNA-HOIST DC shows 'Door is stopped' message?
- R
  Ronald CollinsAug 25, 2025
  The 'DOOR IS STOPPED' message may appear due to an obstruction or the door being jammed. Remove any obstructions and free up the door. Turn off the AC power and test operate the door with battery power. The pusher springs might be preventing the door from reaching the open limits; remove them and install the upper limit brackets supplied with the operator, or set the OPEN limit so that the pusher springs are not engaged. Also, the encoder may not be properly positioned; check and adjust it as described in the installation manual.

How to troubleshoot Richards-Wilcox Door Opening System that does not work on battery power?
- M
  Michael StricklandAug 28, 2025
  First, check if the in-line fuse on the battery red wire is blown and replace it if necessary. Then, check the battery voltage; if it's low, let the batteries charge for 24 hours with AC power on. Replace the batteries if they still don't charge, and replace the control board if the batteries are charged. Also, ensure the door is balanced properly. Finally, make sure the main power to the unit is off.

What causes Richards-Wilcox DYNA-HOIST DC door to move few inches and stops?
- J
  Jessica SaundersSep 1, 2025
  If the door moves only a few inches after an open/close command and then stops, it might be due to the jumper between the ‘S’ and ‘+24’ terminals being removed; if no push-button station has been wired in its place, reinstall the jumper. Alternatively, the remote push button may not have the NC (normally closed) contact for the stop button; replace the push button station (or the contact for the STOP button) with one that has an NC contact on the STOP button. Also, the remote push button station could be wired incorrectly; check and correct the wiring as necessary.
