Continued on page 32 Learning the A-Z's of operator troubleshooting is not something that can be quickly accomplished. However, a few aggressive persons have done so faster than normal which is 3 to 4 decades for some. Regardless, a person still needs the opportunity to learn, meaning having the chance to actually work on operators to gain experience. Gaining knowledge on operators is one of the toughest things to master. A person must be engaged, focused, and proactive in their learning voyage. Addressing the topic of troubleshooting, sometimes one can find a component that has malfunctioned by simply looking at it, but to truly verify a component, a tester is required. Dependable and inexpensive meters are available, and I suggest buying a cheap meter first because you will most likely break or lose it. With this tool you can verify voltage, contacts, circuits, and most important operator components. Start small with components like limit switches or push-buttons. Set the tester on the continuity setting (ohms). The sign for Ohms looks like an upside down horseshoe, as follows: With the meter on this setting, you should hear a beep every time you touch the two meter leads together. Once you have verified the audible beep, you can place the leads on a pushbutton and press it in. If the button is good, you will hear the beep. There is so much more to testers than this, but testing buttons is a good place to begin. The next best step is to set the meter on the AC volts setting, and stick the meter leads in the two slots of a wall Most garage door service personnel I have met yearn to know more about products they install and service. One can spend years replacing hinges, cables, and springs which will lead to becoming a competent garage door serviceman (woman). This experience will do with the majority of service calls, but eventually one will be required to troubleshoot a difficult operator issue, and to be successful you must be well prepared.
