Generator Electrical Problems We Diagnose and Repair in Zuni Pueblo, NM
Standby and portable generators are complex systems with both mechanical and electrical components. Our licensed electricians focus on the electrical aspects of generator failure, which include issues with the automatic transfer switch, control board power supply, battery charging circuits, generator output voltage and frequency regulation, breaker failures within the generator panel, and the wiring connections between the generator and the home or business electrical system.
The automatic transfer switch is one of the most critical components in a standby generator system and one of the most common sources of generator failure in Zuni Pueblo, NM properties. The ATS monitors utility power and automatically disconnects the home from the utility grid and connects it to the generator when power is lost, then reverses the process when utility power returns. Failures in the ATS can cause the generator to fail to start during an outage, fail to transfer power to the home even when the generator is running, or create dangerous backfeed conditions.
Generator control board failures often present as no-start conditions, failure to complete self-tests, false alarm shutdowns, or generators that start but immediately shut down before coming to full power. The control board manages the entire startup sequence including engine pre-heat cycles, voltage buildup, frequency stabilization, and load acceptance. Our electricians diagnose control board issues with manufacturer-appropriate procedures.
The electrical connection between a generator and the home's electrical system must meet strict safety requirements in Zuni Pueblo, NM. All generator hookups must incorporate a properly installed transfer switch or interlock mechanism that prevents the generator from feeding back onto the utility grid, a dangerous condition known as islanding. We install and inspect all types of generator connection systems including whole-home ATS, manual transfer switches, and panel interlock kits.
Signs Your Generator Needs Immediate Service Before the Next Outage
A generator that failed to start during the last outage, shows trouble codes on its control panel, trips its own main breaker when loaded, runs rough or shuts down under load, failed its most recent self-test, or has not been professionally serviced in more than 12 months needs attention before you need it again.
