Fixed the problem a reasonable cost.
The replacement circuit board worked as promised. More importantly, or valuable, was the email assistance I received along the way from MD's support. I had originally thought my motor was bad, but with their help I was able to narrow down my problem and find an appropriate solution. Not having much electrical experience I would not have been able to DIY this project without their help. Thank you!
Worked has advertised -- just need to get the wiring correct since the older unit did not use a circuit board - it is working and no problems
This was a good option for replacing the relay board on my NuTone cv-350. The install was fairly easy & it worked fine. But, replacing the relay board just confirmed my fear that the 20 year old motor was failing and causing this & the past two OEM boards to burn out. Oh well; lesson learned; stuff gets old & breaks down.
The board did not work, repair person said it was a faulty board and has been in touch with customer service but no resolution yet. The board needed to be returned.
MD Notes: We have been in touch with the customer and are working toward a remedy.
Routine. I required a refund and they processed it quickly.
Works as a universal replacement to the Nutone VX-550 circuit board in a 15 yr old unit. Mounting was a challenge but rigging it up to fit where the 2nd motor would be on a larger unit works great.
Worked great!! Allowed me to upgrade a 30 year old Pullman Built in Vacuum from a mechanical transformer and switch to a a circuit board. Very pleased.
Very easy to install and worked great. There are no wiring instructions included with the circuit board itself, which would be nice, however, they are available on the website. Sure beats having to pay for a new central vac.
New circuit board replaced old low voltage control unit, took awhile to troubleshoot in getting it hook up right following instructions from MD, but finally is working correctly.
Finally installed the circuit board. Fairly simple to do. Works great!
Worked well and fixed vacuum that was stuck on. Slight modification to mount it (new hole drilled) as existing unit from the 90s. Thanks!
I had an excellent experience with MD Central Vacuum. Their part saved me a fortune in having to replace our vacuum system.
Worked perfectly for my board that went bad
Part arrived from California to Canada in 2 days. Fit perfectly.
Circuit board works great. It was great to have something that works as advertised. No problem at all with the connections.
Worked fine, but not a direct plug in replacement for the factory unit, does require some basic electrical knowledge and tools. Follow instructions on the product page.
Fast service, easy to look up parts in the website. The relay fit perfectly and now I can control the motor remotely from the handle again.
Works perfectly for my old Hayden Supervac 3600 without having to drill a new hole. Thanks!
