LiftMaster Garage Door Opener Troubleshooting
Service Request: Mr. Jackson’s LiftMaster garage door opener could not open the door, even though all parts appeared in good condition.
Our Solution: Mr. Jackson tried to work the problem out himself, but was unable to locate the source. We began by examining the hardware parts of the door ourselves, as sometimes the professional eye can catch something that an inexperienced spectator may miss. We ran some tests on the opener as well, seeing if the limit switches were set right and if the chain drive wasn’t slack or adjusted too tightly. After a short while, we found the source of the problem in the opener logic board. It had some damage to the wiring, causing it to fail to work properly. We replaced the logic board and reprogramed the garage door opener to work with the remote again.
Broken Garage Door Cable
Service Request: Mrs. Monk needed us to replace a garage door cable that broke after getting snagged on something.
Our Solution: While many people know the importance of garage door springs, cables actually have just as crucial a role. The lift cables of garage doors do what their name suggests. They help lift the door. When one breaks, as it did for Mrs. Monk, the door can list to one side, and struggle to move. We came with a new cable of matching properties to support the weight of her garage door. The second cable (on the other side of the door) was in good shape so it didn’t need replacement.
