Raynor COMMANDER 2000RGD garage door opener troubleshooting
Raynor COMMANDER 2000RGD is a residential garage door opener powered by a 1/2 HP motor. It is important to point out that the door operator system won’t work correctly unless the protector system is properly aligned. The troubleshooting tips below will enable you to fix the garage door opener on your own in case of minor issues.
| Situation | Probable Cause & Solution |
| The opener doesn 7 operate from either the door control or the remote control: | 1. Docs the opener have electric power? Plug a lamp into the outlet. If it doesn't light, check the fuse box or the circuit breaker. (Some outlets arc controlled by a wall switch.) |
| 2. Have you disabled all door locks? | |
| 3. Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction. | |
| 4. The garage door spring may be broken. Have it rcplaccd. | |
| 5. Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes. Try again. | |
| Opener operates from the remote control, hut not from the door control: | 1. Is the door control push bar lit? If not, Remove the bell wire from the opener terminal screws. Short the red and white terminals by touching both terminals at the same time with a piccc of wire. If the opener runs, check for a faulty wire connection at the door control, a short under the staples, or a broken wire. |
| 2. Arc the wiring connections correct? Review Installation | |
| The door operates from the door control, but not from the renwte control: | 1. Is the door push bar flashing? If your model has the Lock feature, turn it off. |
| 2. Your opener needs to re-lcam a remote control code. | |
| 3. Program the receiver to match the remote control code. | |
| 4. Repeat the rccciver programming procedure with all remote controls. | |
| The remote control has short range: | 1. Change the location of the remote control in your car. |
| 2. Check to be sure the antenna on the right side panel of opener extends fully. | |
| 3. Some installations may have shorter range due to a metal door, foil backcd insulation, or metal garage siding. | |
| Opener noise is disturbing in living quarters of home: | If operational noise is a problem bccause of proximity of the opener to the living quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to minimize vibration to the house and is easy to install. |
| The garage door opens and closes by itself: | 1. Be sure that all remote control push buttons and battery indicator lights arc oil'. |
| 2. Remove the bell wire from the door control terminals and operate from the remote control only. If this solves the problem, the door control is faulty (rcplace), or there is an intermittent short on the wire between the door control and the opener. | |
| 3. Clear memory and reprogram all remote controls. | |
| The door doesn’t open completely: | 1. If the door has been working properly but now doesn't open all the way, increase the up force. |
| 2. Is something obstructing the door? Remove the obstruction or repair the door. | |
| 3. If door opens at least 5 feet, the travel limits may need to be increased. One turn equals 2 inches of travel. Repeat the safety reverse test after the adjustment is complete. | |
| The door stops but doesn't close completely: | Review the travel limits adjustment procedures Repeat the safety reverse test after any adjustment of door arm length, close force or down limit. |
| The door opens but won't close: | 1. If the opener lights blink, cheek the safety reversing sensor. |
| 2. If the opener lights do not blink and it is a new installation, check the down force. For an existing installation, sec below. Repeat the safety reverse test after the adjustment is complete. | |
| The door reverses for no apparent reason and opener lights don't blink: | 1. Is something obstructing the door? Pull the manual release handle. Operate the door manually. If it is unbalanced or binding, call for professional garage door service. |
| 2. Clear any ice or snow from the garage floor area where the door closes. | |
| 3. Review the force adjustment procedures | |
| 4. If door reverses in the fully dosed position, dccrcasc the travel limits. Repeat the safety reverse test after adjustments to force or travel limits. The need for occasional adjustment of the force and limit settings is normal. Weather conditions in particular can affect door travel. | |
| The door reverses for no apparent reason and opener lights blink for 5 seconds after reversing: | Check the safety reversing sensor. Remove any obstruction or align the receiving eye. |
| The opener lights... | Don't turn on: Rcplacc the light bulb(s) (100 watts maximum). Use a standard neck garage door opener bulb if regular bulb burns out. don't turn off: Is the Light feature ow? Turn it off. |
| The opener strains or nuiximum force is needed to operate door: | The door may be out of balancc or the springs arc broken. C lose the door and use the manual release handle to disconnect the trolley. Open and close the door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it docs not, disconnect the opener and call for professional garage door scrvicc. Do not increase the force to operate the opener. |
| The opener motor hunts briefly, then won't work: | 1. The garage door springs arc broken. Sec above. |
| 2. If the problem occurs on the first operation of the opener, door mav be locked. Disable the door lock. Repeat the safety reverse test after the adjustment is complete. | |
| The opener won't operate due to power failure: | 1. Use the manual release handle to disconnect the trolley. The door can be opened and elosed manually. When power is restored, press the Door Control push bar and trolley will automatically rcconncct (unless trolley is in lockout position.) |
| 2. The Outside Quick Release accessory (lor use on garages with no scrvicc door) disconnects the trolley from outside the garage in ease of power failure. |
