The automatic transfer switch is what moves your home from utility power to the generator, and back again. If it fails, the generator can run perfectly and the house stays dark. It also protects utility workers by keeping the generator from feeding power back into the grid.
Signs of a transfer switch problem:
- The generator starts during an outage but the house has no power
- The switch clicks, buzzes or does not move
- The generator does not start when the power goes out, because the switch is not sending the start signal
- Lights flicker or the load drops out when switching
Transfer switch work involves your home's electrical system, so it should be done by a qualified person. Call and describe what you see, and we will connect you with a local provider.
