Question about Broan-NuTone CV353 Central Vacuum
You need to determine if this is a problem with the hose or the unit. I would recommend plugging my hose in the wall sideways. This should make your central vacuum run continuously. If the unit doesn't cut on and off it is the hose. If it still cuts on and off it is probably the relay.

SOURCE: I have a nutone CV-750,
It sounds like you could have one of two problems. I would guess either a short in your house, or a bad relay. If you plug you hose in sideways it will bypass the low voltage wire in the hose. If the unit doesn't shut on and off then you have a short and need a new hose. If the unit continues to cut on and off then you probably need a new relay. The relay is really easy to change out yourself and there are places to buy online.
