I have installed a central vac in my home, it has 4 inlets for the hose and one vacupan in the kitchen that sucks up trash that is swept off the floor. The on/off operation is low voltage and makes contact (turns the unit on) when the hose is inserted in the room outlet. My problem is that when the motor is plugged in, it starts to run without the hose being plugged in anywhere. The vacumn function works fine, the on/off operation is the problem. I have to plug and unplug the motor (located in the garage) to get it to run.

Any suggestions or help will be greatly appreciated.
