| Symptom: | Solution: |
| One or both of the Indicator lights on the safety reversing sensors do not glow steady | Inspect sensor wires for a short (staple in wire), correct wiring polarity (black/white wires reversed), broken or disconnected wires, replace/attach as needed |
| Disconnect all wires from back of motor unit | |
| Remove sensors from brackets and shorten sensor wires to 1-2 ft. (30-60 cm) from back each of sensor | |
| Reattach sending eye to motor unit using shortened wires. If sending eye indicator light glows steadily, attach the receiving eye | |
| Align sensors, if the indicator lights glow replace the wires for the sensors. If the sensor indicator lights do not light, replace the safety sensors | |
| LED is not lit on door control | Inspect door control/wires for a short (staple in wire), replace as needed |
| Disconnect wires at door control, touch wires together. If motor unit activates, replace door control | |
| If motor unit does not activate, disconnect door control wires from motor unit. | |
| Momentarily short across red and white terminals with jumper wire. If motor unit activates, replace door control wires | |
| Sending indicator light glows steadily, receiving indicator light is dim or flashing | Realign receiving eye sensor, clean lens and secure brackets |
| Verify door track is firmly secured to wall and does not move | |
| Motor has over heated; the motor unit does not operate or trolley is stuck on stop bolt = Motor unit hums briefly; RPM Sensor = Short travel 6-8“ (15-20 cm). | Unplug unit to reset. Try to operate motor unit, check diagnostic code |
| If it is still flashing 5 times and motor unit moves 6-8’ (15-20 cm), replace RPM sensor | |
| If motor unit doesn't operate, motor unit is overheated. Wait 30 minutes and retry | |
| Motor unit doesn’t operate | Replace logic board because motor rarely fails |
| Situation | Probable Cause & Solution |
| The opener doesn’t 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 replaced. | |
| 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 piece 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. Are the wiring connections correct? | |
| The door operates from the door control, but not from the remote control: | 1. If your model has the Lock feature, turn it off. |
| 2. Is the wall push button flashing? Your opener needs to re-leam a remote control code. | |
| 3. Does the battery test light glow when the remote control push button is pressed? If not, replace the battery. | |
| 4. Program the receiver to match the remote control code. | |
| 5. Repeat the receiver programming procedure with all remote controls. | |
| The remote control has short range: | 1. Check the battery test light. If the light is dim, replace the battery. |
| 2. Change the location of the remote control in your car. | |
| 3. Check to be sure the antenna on the right side panel of opener extends fully. | |
| 4. Some installations may have shorter range due to a metal door, foil backed insulation, or metal garage siding. | |
| Opener noise is disturbing in living quarters of home: | If operational noise is a problem because 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 off. |
| 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 (replace), or there is an intermittent short on the wire between the door control and the opener. | |
| The door doesnt 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 |
| Repeat the safety reverse test after any adjustment of door arm length, close force or down limit. | |
| The door opens hut wont close: | 1. If the opener lights blink, check the safety reversing sensor. |
| 2. If the opener lights do not blink and it is a new installation, check the down force. | |
| Repeat the safety reverse test after the adjustment is complete. | |
| The door reverses for no apparent reason and opener lights dont 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 | |
| 4. If door reverses in the fully closed position, decrease 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: | Cheek the safety reversing sensor. Remove any obstruction or align the receiving eye. |
| The opener lights dont turn on:... | Replace the light bulb(s) (100 watts maximum). Use a standard neck garage door opener bulb if regular bulb bums out. |
| Is the Light feature on - Turn it off. | |
| The opener strains or maximum force is needed to operate door: | The door may be out of balance or the springs arc broken. Close 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 does not, disconnect the opener and call professional garage door service. Do not increase the force to operate the opener. |
| The opener motor hums briefly, then wont work: | 1. The garage door springs arc broken. |
| 2. If the problem occurs on the first operation of the opener, door may be locked. Disable the door lock. | |
| Repeat the safety reverse test after the adjustment is complete. | |
| The opener wont operate due to power failure: | 1. Use the manual release handle to disconnect the trolley. The door can be opened and closed manually. When power is restored, press the Door Control push bar and trolley will automatically reconnect (unless trolley is in lockout position.) |
| 2. The Outside Quick Release accessory (for use on garages with no service door) disconnects the trolley from outside the garage in case of power failure. |
| Problem: | Solution: |
| The garage door opens and closes by itself | 1. Is there a neighbor with a garage door opener using the same frequency code? Change your code. |
| 2. Make sure that none of the transmitter push buttons is stuck in the "down" position. | |
| 3. Remove bell wire from opener terminals and operate from transmitter only. If this solves the problem, the Wall Push Button is faulty (replace), or there is a short or broken wire between Wall Push Button and opener. | |
| Door doesn’t open completely | 1. Is something obstructing the door? |
| 2. If door opens at least 5 feet, travel limits may need to be increased. One turn equals | |
| 2 inches of travel. REPEAT SAFETY REVERSE TEST after the adjustment is complete. | |
| 3. If door has been working properly but now doesn't open all the way, increase the UP FORCE. REPEAT SAFETY REVERSE TEST after the adjustment is complete. | |
| Door doesn’t close | 1. Is something obstructing the door? |
| Completely | 2. Review the Travel Limits Adjustment Chart REPEAT SAFETY REVERSE TEST after any adjustment of door arm length, close force or down limit. |
| Door reverses for no | Is something obstructing the door? Pull red emergency release handle. Operate door manually. If it is unbalanced or binding, call for professional garage door service. Clear any ice or snow from garage floor area where garage door closes. |
| Apparent reason | Review the Force Adjustment REPEAT SAFETY REVERSE TEST after adjustment is complete. |
| If door reverses in FULLY CLOSED position, decrease travel limits | |
| REPEAT SAFETY REVERSE TEST after the adjustment is complete. The need for occasional adjustment of the force and limit settings is normal. weather conditions in particular can affect door travel. | |
| Opener light does not turn on | Replace the light bulb (75 watts maximum). Use a “garage door opener bulb" if standard bulb bums out prematurely due to vibration. Vibration may be caused by loose end panel. Retighten screws. |
| Opener light does not turn off | 1. There may be a defective ground at ceiling or wall receptacle. Unit must be grounded. |
| Opener strains or maximum | 1. Door may be out of balance or springs are broken. Close door and use emergency release rope and handle to disconnect trolley. Open and close door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not. call for professional garage door service. |
| Opener motor hums | Garage door sings are broken. |
| Briefly, then wont work | The trolley may be jammed into stop bolts. Pull or push on door while motor is humming to release jammed condition. Re-adjust door limits to prevent over-travel. |
| REPEAT SAFETY REVERSE TEST after adjustment is complete. | |
| If the problem occurs on first operation of the opener, door is locked. DISABLE DOOR LOCK. If chain was removed and reinstalled, motor may be out of phase. Remove chain; cycle motor to the down position. Observe drive sprocket. When it turns in clockwise direction and stops in down position, reinstall chain. | |
