Average lifespan of 8 – 10 years can be expected, although there are operators out there which last as little as 5 years yet as long as 25 years (or more!). If your operator is getting old, consider replacing it with an up-to-date machine with all the latest safety features. New openers now offer upgrades such as a battery backup system in case of a power outage, and remote accessories that can tell you if your garage door has been left open, or opened while you are away.
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.
You most likely have a burned drive belt, although there is the possibility of having a burned circuit board or capacitor. All are easily replaced.
A humming operator is usually the outcome of a burned out capacitor.
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.

Yes. Older openers use switches in either the “on” or “off” position. This type of RF (radio frequency) stays the same; therefore anyone with a code-grabbing device can steal your code and use it anytime. Newer openers have the technology that uses a combination of over 4.3 billion possible combinations…making it impossible for someone to steal the code. We sell brand new Liftmaster Operators with this new technology.
Check to see that the power head is securely mounted and the door operates freely. Review “Door Balance Tests: in the manual. Is something obstruction the door?
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. If the photo sensor beam is broken (walking in and out of the garage while door open) it will reset every time it is broken.
