Why is my DUOVAC Central Vacuum System not turning on?

If your DUOVAC Central Vacuum System is not turning on, the issue might be due to several reasons. First, ensure that the power level (voltage/amperage) meets the power unit's requirements. A malfunction of the motor or control module could also be the cause; check that the power cord is directly plugged into a power outlet. The unit has a mini breaker (button on the side of the motor housing) to protect against overload. Try resetting it. If the problem persists, it may be low voltage wiring; you can test this by short-circuiting the low voltage terminals on the motor housing with a screwdriver (rubber handle). If it starts, the wiring is the issue. Also, check the breaker on your electric circuit panel.
