Dealing with Travel Switches Effectively03/11/2014 Back To Blog
It is important to note that travel switches are not limitless resources. The Garage door repair teams in Arlington Heights understand this. Just like the work that is undertaken on genie installations, this is a process that requires concentration and technical skills. The first assumption is that the openers and safety electric eyes are working as they should. Make sure that you remove the cover once the unit is unplugged. This is delicate painstaking work that can easily go wrong in the wrong hands. Remove some machine screws at strategic points so that you do not have to deal with the full force of the entire structure. Normally these are found around the case. Set the cover aside with the screws nearby so that you know what goes where.
Gear Motors and Accessories
Many structures will have a motor as well as a set of gears. This is not too far off the circuit board. The travel limit itself has two metal fingers. There is also a small carriage which runs on the threaded rod. You can adjust these locations with the help of a good strong screw driver. The fingers must move in response and the wires must be tightened appropriately. With any luck you will not need to do any more but it is best be thorough with the checks.
Powering the Opener
Most experts in Illinois are convinced that electric motor burnout is a rare thing and they are correct. For example there is a thermal cutout which plays an important role in protecting the structure from overheating even if it is off track. Humming is a sign that the gears are jammed in some way and need to be released appropriately. Normally the thermal limit will reset automatically on the modern installations where everything is mechanized. Nevertheless this checking process should be undertaken on a regular basis as part of an overall maintenance program.
