If the top comes off, it will be by the motor and exhaust. Just replace it with the new one, make sure you don't mix up any wires. Also unplug it from the AC first.

If the central vacuum tank will not turn OFF even with the switch in the “OFF” position, then the low-voltage wires should be disconnected from the tank. If the tank continues to run and still will not turn off, then most likely the relay inside is defective (but it could be a defective and/or shorted ON/OFF switch). If with the low-voltage wires disconnected the tank is able to then be turned off with the switch, then there is a short in the low-voltage wires or a hose is plugged into an inlet somewhere. ~ TTURAMBAR

SOURCE: have a nutone CV-450. Suction is gone at the

The first thing to do is to disconnect the pipe coming into the unit. If there is suction there than you probably have a break in the line. If there is no suction when you disconnect the pipe coming into the unit than it is most likely the motor gasket. This gasket can sometimes get sucked into the motor causing problems. Remove the lid to the central vacuum, than disconnect the motor, you should be able to tell if maybe the gasket has been off center or if it has been sucked up in the motor.
