    Force Adjustments The force adjustments regulate the amount of power the garage door opener uses to open and close the door. The adjustment screws are typically located on the back panel of the overhead motor unit. Following are instructions on how and when to adjust the forces.

Please keep in mind that too much force will interfere with the proper operation of the safety reverse system. The door might not reverse properly when required and could seriously injure or kill someone. Do not increase the force beyond the minimum amount required to close the door. Do not use the force adjustments to compensate for a binding or sticking garage door. Always test the safety reverse system following all adjustments to force levels. Test the DOWN (close) Force: Grasp the bottom of the door when the door is about half way through the DOWN (close) travel. The door should reverse. (Please keep in mind that reversal halfway through down travel does not guarantee reversal on a one-inch obstruction.) If the door is hard to hold or doesn’t reverse, decrease the DOWN (close) force by turning the down force control counterclockwise. Make ten degree turn adjustments until the door reverses normally. After each adjustment, run the opener through a complete travel cycle. Test the UP (open) Force: Grasp the bottom of the door when the door is about half way through the UP (open) travel. The door should stop. If the door is hard to hold or doesn’t stop, decrease the UP (open) force by turning the up force control counterclockwise. Make ten degree turn adjustments until the door stops easily. After each adjustment, run the opener through a complete travel cycle. If the door doesn’t open at least five feet: Increase the UP (open) force by turning the up force control clockwise. Make ten degree turn adjustments until the door opens fully. Re-adjust the UP Limit if necessary. After each adjustment, run the opener through a complete travel cycle. If the door reverses during the down (close) cycle and the opener lights are not flashing: Increase the DOWN (close) force by turning the down force control clockwise. Make ten degree turn adjustments until the door completes a close cycle. Re-adjust the UP Limit if necessary. After each adjustment, run the opener through a complete travel cycle. DO NOT increases the force beyond the minimum amount required to close a properly adjusted and balanced door. Perform the 1” Safety Reversal Test: With the door fully open, place a one-inch board (or a 2x4 laid flat) on the floor, centered under the garage door. Operate the door in the down direction. The door must reverse on striking the obstruction. If the door stops on the obstruction, it is not traveling far enough in the down direction. Increase the DOWN limit (located on the side of the overhead motor unit) by turning the DOWN limit adjustment screw counterclockwise (opposite of arrow) 1/4 turn. Repeat test. On a sectional door, make sure limit adjustments do not force the door arm beyond a straight up and down position. When the door reverses on the one-inch board (or a 2x4 laid flat), remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment. If the door will not reverse after repeated adjustment attempts, call for professional garage door service. Repeat this test once a month and adjust as needed.

Travel Adjustments
The travel (limit) adjustments regulate the points at which the door will stop when moving up or down. These adjustments are located on the side of the overhead motor unit. Following are adjustment procedures on how and when to adjust the travel to your opener. Please keep in mind that improper adjustment of the travel limits will interfere with the proper operation of the safety reverse system. The door might not reverse properly when required and could seriously injure or kill someone. Please remember to perform the 1" safety reversal test after any travel adjustment.

If the door does not open completely, but opens at least five feet: Increase the UP travel. Turn the UP travel (limit) screw clockwise. One turn equals approximately 2” of travel. (NOTE: To prevent the trolley from hitting the stop bolt, keep a minimum distance of 2-4” between the trolley and the bolt.) If the door does not close completely (stops short of the garage floor while in the close cycle and does not reverse): Increase the DOWN travel. Turn the DOWN travel (limit) adjustment screw counterclockwise. One turn equals approximately 2” of travel. If the door reverses after coming in contact with the garage floor: Decrease the DOWN travel. Turn the DOWN travel (limit) adjustment screw clockwise. One turn equals approximately 2” of travel. Perform the 1” Safety Reversal Test: With the door fully open, place a one-inch board (or a 2x4 laid flat) on the floor, centered under the garage door. Operate the door in the down direction. The door must reverse on striking the obstruction. If the door stops on the obstruction, it is not travelling far enough in the down direction. Increase the DOWN limit by turning the DOWN limit adjustment screw counterclockwise (opposite of arrow) 1/4 turn. Repeat test. On a sectional door, make sure limit adjustments do not force the door arm beyond a straight up and down position. When the door reverses on the one-inch board (or a 2x4 laid flat), remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment. If the door will not reverse after repeated adjustment attempts, call for professional garage door service. Repeat this test once a month and adjust as needed.

Remote Control Range Issues
The range issues could be related to radio frequency interference that comes from something in your home or in the surrounding environment. Certain electrical devices can radiate interference; this could be almost anything that is plugged into an electrical outlet, though some are more likely than others. This includes TV cable, cable amplifiers, surge protectors, fluorescent lights, battery charging devices (power tools, golf carts, etc.), anything that utilizes a timer (sprinkler systems, lights, alarm systems, etc.) and a myriad of others. If the problem seems sporadic, we can safely assume that the device responsible for the interference is only being operated during those times.

To isolate the interference turn the circuit breaker off to the garage and plug the garage door opener into an extension cord from another room. If the range improves, then the interference is coming from a device in the garage. If no improvement is seen follow the same procedure, this time turning off the circuit breakers to your home, with the exception of the garage, and test the remote controls If improvement is noted, turn the circuit breakers back on, one by one, until the range problem resurfaces. This will allow you to narrow down what room the problem device is in. You will have to go from there to isolate it further, by unplugging and re-plugging the items in that room.

Safety Sensor Issues
If the door will not close unless constant pressure is applied to the wall button, the symptoms are indicative of a safety sensor issue. There are a few different things that can cause this type of problem, so listed below are the issues with their corresponding solutions.

1. Check each sensor for a steady glowing indicator light. If both indicator lights are on, or if one indicator light is flickering, the sensors may be slightly misaligned. To check for misalignment; obstruct the beam of the sensors so that they cannot see each other. When the beam is blocked, the indicator light on one of the two sensors will temporarily go out. This is the receiving sensor. Remove the obstruction and loosen the wingnut on the back of the receiving sensor. Adjust the receiving sensor until the green indicator light is bright and steady, then retighten the wingnut. This usually takes a couple of attempts before it is back in alignment.

2. If an indicator light is out on only one of the sensors, check for a possible loose wire. Sensor wires are attached to the white and black terminals on the back or side panel of the overhead motor unit. If wires are securely connected, check the wires running from the sensor to the motor unit for any breaks. Check anywhere the wires are spliced together. Try moving the wire around where it is connected at the back of the sensor. If the indicator light does not come on, you will need to replace the sensors.

3. If the problem exists only during the daytime, check to make sure the receiving eye is not in direct sunlight. If this is the case, it may be necessary to remount or adjust the sensor back toward the side wall of the garage.

   Motor Hums Briefly and Door Does Not Move The inner trolley may be stuck on the stop bolt. Below is listed the step-by-step procedure to resolve this issue.

4. First, verify that the trolley is stuck on the stop bolt.

5. Disconnect the garage door from the garage door opener, by pulling the red manual release rope straight down and then back toward the motor unit. This will allow you to close the door by hand.

6. Chain tension is adjusted using two nuts and a threaded shaft; located on the inner trolley. If you are inside of the garage looking out, you will find these adjustment nuts on the left hand side of the T-rail. Loosen the outer nut (the nut closest to the garage door) 4 to 5 turns. This helps relieve the ‘bind.’

7. Run the unit from either the remote control or wall button. The trolley should travel toward the door and stop. If it re-engages with the door, pull the Emergency Release Handle to disengage it.

8. With the trolley in the down position, decrease the up-travel by turning the Up Travel screw 2 full turns opposite of the arrow. (DO NOT decrease up travel while trolley is still stuck on the stop bolt otherwise the center contact on the limit switch assembly will become bent.)

9. To add tension to the chain; tighten the outer nut. With every turn of the outer nut, the chain will rise slightly. Keep your eye on the midpoint of the rail; when the chain is approximately 1/2” above the bottom of the T-rail at the T-rail midpoint; tighten the inner nut (the nut closest to the motor) to secure the adjustment. The chain is now properly adjusted.

NOTE: If the inner trolley does not move off the stop bolt, repeat steps 2-6 above.

Unit Does Not Respond to Any Commands
If the garage door opener does not respond to commands from either the remote control or the wall button, the Receiver Logic Board may be damaged. Below are instructions for testing the Receiver Logic Board; this consists of disconnecting the Wall Control Button and shorting across the red and white wire terminals.

1. Locate the red and white terminals on either the rear end or right hand side panel of the overhead motor unit. You may need to remove a light lens cover in order to see them.
2. Disconnect the red and white wall control wires from the motor unit at the red and white terminals. Leave the other white wires from the safety sensors connected to the white and black terminals.
3. If you have screw terminals on your opener: (Wires wrap around the screws) Use an insulated screw driver or a pair of needle-nose pliers with insulated handles to short across the red and white terminals.

If you have quick connect terminals: (Wires plug into the terminals.) Strip 1/2” of insulation from each end an insulated wire and short across the red and white terminals.

Shorting across the red and white terminals should cause the motor to run. If the unit only clicks and/or the opener light comes on, the Receiver Logic Board will have to be replaced.

Using your opener's self-diagnostic capabilities (when 'Learn' button LED flashes)
1 FLASH OR 2 FLASHES - Safety sensors wire open (broken or disconnected)

Symptom: One or both of the Indicator lights on the safety 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 from back of each 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.

3 FLASHES - Door control or wire shorted Symptom: LED is not 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.

4 FLASHES - Safety Sensors slight misaligned (dim or flashing LED) Symptom: 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.

5 FLASHES - Motor overheated or possible RPM sensor failure. Unplug to reset. Symptom: 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 inches. - 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 inches, replace RPM sensor. - If motor unit doesn’t operate, motor unit is overheated. Wait 30 minutes and retry. If motor unit still will not operate, replace logic board.

6 FLASHES - Motor Circuit Failure. Replace Receiver Logic Board. Symptom: Motor unit doesn’t operate. - Replace logic board because motor rarely fails.
