this was super helpful. i yanked a working motor/blower from a slightly older system one unit that had a dead humidifier circuit(found it had melted the connector inside) and moved it to my newer bipap unit. works great, dead silent. mine had bad bearings…so loud. great article. thank you for saving me money, time…..SLEEP!
