Question about Broan-NuTone CV353 Central Vacuum
Open the door on the inlet port and look inside. You should see 2 small pins. These pins are spring loaded to make contact with the metal end of your hose when you plug it in. Two low voltage wires are screwed to the underside of these pins. The low voltage wires go all the way back to the low voltage switch/relay on your central vac power unit.
Sometimes one or both of these pins will just break so that they don't make contact with the end of your hose. If you see no pins or just one then you will have to replace the inlet cover.
If both pins are present; push down on them with your finger. If you feel resistance then your inlet is probably OK.
CAUTION: IF YOUR CENTRAL VAC INLETS HAVE A 110 VOLT CONNECTION, REMOVAL/REPLACEMENT OF YOUR INLET SHOULD ONLY BE DONE BY A QUALIFIED ELECTRICIAN.
Remove the two screws in the faceplate. Carefully slide the inlet cover out. Check the two screw on wiring connections. Make sure both wires are securely attached and that there are no breaks.
If neither of the above fixed your problem, you may have a broken or disconnected wire somewhere between this inlet and the low voltage witch at your power unit.
