The standby generators offer more power and easy operation without extension cords. They are hardwired into the home and are structurally more complex. If any issues arise on your standby generator and electric motors, it is better to call a professional to repair them on-site. What is involved in On-site repair services of Generators/Motors? Initial inspection: When you are unaware of the exact issues with your motor or generator, it is hard to say what you can predict once the technician arrives.   The technician will first perform a quick inspection to identify any obvious problems, such as damage on the outside of the box or anything that might appear broken. Checking Connectivity: The next step of a technician is to check whether the generator has tripped or is off. This issue is generally caused by something similar to blown-fuse or a problem with the cable or its connection to the main house network. If everything is perfect, the next step is to check for leaking voltage on the generator. Voltage Regulation: When the generator is off, you cannot be able to detect any residual voltage. But, the presence of a residual voltage (even as little as 5 Volts AC) could signal many problems. The most obvious problem could be the improper working of the voltage regulator. A technician might require to open up the generator and check each issue separately to identify which one provokes the generator to malfunction. Fixing the issue: Once the issue has been detected, the generator or motor is fixed immediately, or it could take a day or two. This banks on whether parts need to be replaced or how extensive the problem is. Sometimes the issue is simple, such as a tripped circuit, and can be fixed right away. In other cases, it might require a second visit with additional equipment. Or the technician might need to take a component away and return it once after fixed.
