We had a central vacuum cleaner in the 94 Dolphin, our previous motorhome. My wife really liked it and wanted one on our newer 03 Horizon. I purchased a Dirt Devil CV950 Central Vacuum System from RV Upgrades. After getting it installed a test try showed that it would not work. I finally traced the problem to the internal circuit board and further to the 24 Volt transformer that supplies the voltage to the relay which controls the power to the motor. The primary was open. A call to Dirt Devil was made and the lady there sent me a new circuit board. After installation, the system now worked very well. After nearly one year the system was again dead. Analysis showed the same problem.
I removed the transformer from the PC board and routed 2 wires (24Volts) out to an external wall transformer purchased from Radio Shack. The new transformer will supply 1 amp (the original transformer was rated at 40 mA) and should never go bad again. It works great again.
If anyone has the same problem with the CV950 this could be the answer.
