Other than the voltage rating on these new caps being 3V instead of 2.5V on the old caps, I see no immediate difference. New ‘no-name’ supercaps that will likely fail in 3 years, so I felt no desire to order top shelf components knowing that it is likely a poorly–engineered circuit design leading to component failure.Ī picture of the ‘improved’ caps on the replacement board from Liftmaster. Some staining to the PCB, but the electrolyte didn’t have a chance to eat any pads or vias, yet…. Ruptured and leaking capacitors do not represent an optimal working condition. Here are some pictures of the old and the new. I went ahead and fixed my existing 888LM anyways. Liftmaster is well aware of this problem and are issuing warranty replacements with no questions asked, which is the right thing to do. I was also fortunate that the problem issues I was having were not as bad as some others have reported, namely the control panel shorting out and raising the door while no one is at your home or business. My garage door does not see a lot of use, so I got 4 years before mine started acting wonky. I initially just figured one of the photo eyes for the light beam were out of whack so I readjusted them back to specs with no improvement in my little issue.Īfter a lot of other troubleshooting and a lot of digging online, I discovered that a pair of 1F supercapacitors in the older 888LM units are guaranteed to fail almost 3 years after the control panel is installed.
