\015 Have a nutone CV-450. Suction is gone at the unit. intake fans seem to be running full power and getting good blast of air from the output pipe. Cleaned filtes. not sure what to check next or how to fix this\015

Answers :

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.
