Genie doesn't manufacture garage doors but openers and their accessories. So, the term Genie garage door repair mainly refers to opener services. Repair is an ambiguous word since it is often used for every service a specific component would need including its replacement, fixing or maintenance. In reality, repairing means restoring damages like fixing the reverse system when the overhead door closes down but opens up again! In any case, the value of Genie garage door repair is great since it will ensure all parts of the electric opener are in good working condition.
The opener sensors often need adjustment and their wirings should be checked for damages especially at the parts where they are stapled. Setting the force limit at the opener unit so that the door will close or open fully and tightening the bolts are small repairs, which will allow to the system to be stable and ensure proper door movement. Since Genie openers have different features depending on the model and also differences from other brands, they must be repaired in accordance to their own specifications but also with the generic safety requirements.
