Opener Does Not Work

A. Make sure power cord is plugged into a properly grounded 3-prong 120 volt outlet. Plug in a drill or other electrical tool to test for power.

B. If opener has been cycled several times, the motor overload protector may be activated. Wait approximately 10 minutes for the motor to cool and try again.

C. If a four-function Wall Console is being used, make sure the Vacation Switch is in the "UNLOCKED" position. The power unit can not be activated nor programmed with the Vacation Switch in the "LOCKED" position.

D. If door is severely out of balance, the opener may not be able to exert enough force to move it. Make sure all locks are removed. Pull the Emergency Disconnect Cord to release the door from the opener. Check to see if the open will operate if not connected to the door. If opener now operates, review "Door Balance Test" in you Owner's Manual.

Hand Held Transmitter Does Not Work or Has Short Range

A. Review the "Radio Coding Instructions" in the Owner's Manual.

B. For Secure Code Openers: If the transmitter button is pressed more than sixteen times when it is out of range of the door opener, it will have to be pressed twice while in range in order to get the transmitter synchronized with the opener.

C. The battery in your transmitter may be dead or weak. Replace the battery with the same type.

D. Try moving or coiling the antenna wire on the opener.

E. CB radios, computer equipment, powerful communication signals, and other door openers may cause undesirable interference and shorten radio range.

Pushbutton Does Not Work

A. Make sure the pushbutton wires are not touching each other at the rear of the opener or at the pushbutton.

B. If the wires are not touching each other and the problem still exists, disconnect the wires from the back of the opener and "short" across the two pushbutton screws using a key or screwdriver. If  opener now operates, the pushbutton wires are probably shorted or broken.

Lights Flash on Opener

A. This may be caused by activating the obstruction system that is controlled by the open or close force adjustment on the rear of the opener. If it requires more force to move the door than the opener can supply, the lights on the opener will blink. A common cause is a poorly operating door or an obstruction. Review "Door Balance Test" and "Open and Close Force Adjustments" in the manual.

B. If the beam sensor is not aligned or working correctly, the door can only be closed by holding the wall-mounted pushbutton. The transmitter cannot be used to close the door. The light on the opener will flash and the door will reverse and open if the pushbutton is not held until the door is fully closed.

C. If something obstructs the door while closing, it will reverse and open - lights will flash. If something obstructs the door while opening, it will stop - lights will flash.

Door Closes - Then Opens When Reaching the Floor

A. Is a rake handle, garden hose, snow, ice, etc. obstructing the door? Remove the obstruction then try closing the door again.

B. Due to climatic conditions many concrete floors will heave or sink. Turn the (small black) close travel adjustment 1/4 turn opposite the direction of the arrow on the cover, then review the "Close Position" and "Entrapment Test" instructions in the manual.

Excessive Tube Bow

A. Check to see that the powerhead is securely mounted and the door operates freely. Review "Door Balance Tests: in the manual. Is something obstruction the door?

B. Review the "Close Position" and "Entrapment Test" instructions in the manual.

Opener Activates by Itself

A. Carefully check the wiring to the pushbutton and electric key switch (if used). An intermittent "short" caused by a staple or frayed wire may be the problem.

Light Stays On

A. The light time delay on the opener will keep the light on for approximately 4-1/2 minutes after the system has be activated, then will turn the light off automatically.

B. If the opener has a worklight switch (which is supplied only with a four-function wall console), slide the switch to "OFF" position.

C. If the opener has a pedestrian switch (which is supplied only with a four-function wall console), the light will stay on for 4-1/2 minutes after the pedestrian door has been opened.

Not Enough Open or Close Travel Adjustment

A. If you operated the power unit before it was completely installed or if you did not position the traveler the correct distance from the tube support, the limits and traveler may be out of synchronization.

B. Turn off power, remove and relocate traveler by disconnecting chain from sprocket, re-assemble and try adjusting again.

Something Broke - Need Assistance?

Identify the part in the manual, then contact your local dealer

A. Reference the proper pages in the manual for all adjustments and settings.

B. If the problem has been located in the radio control (other than batteries), return only the transmitters and the control board. DO NOT return the complete opener.
