Question about Broan-NuTone CV450 Central Bagged Central System Vacuum
The relay that turns the machine off from any of the several places where you connect, is probably stuck.
The relay is operated by low voltage. When you connect your hose, you comlete the low voltage circuit and energize the 110 volt system, and the machine comes on. When you pull the hose out, the relay is suppose to release.
those are my thoughts
I hope this is of value to you.
