SOURCE: Raised vent is Rising after being lowered
Hi,
My RV30S was installed by a qualified service technician in
approximately the year 2000. It finally developed a mind of its own.
It would raise up and run for a bit and then stop....sometimes it
wouldn't raise up or go down....it would switch from fast to slow to
stop.....it became frustratingly unusable....
...today i finally took it upon myself to take it apart and I determined that the controller board had fried.
Before I go on -> Disclaimer: These units are hard-wired to live
A.C. power. These units must be serviced by technically qualified
service personnel. I do NOT recommend anyone to attempt this service.
I've worked in the past as an electrical engineer by trade. But to save
you time and money you can shop and buy the parts you need yourself and
then hire an appliance service technician to safely install them for
you. This way they can't rip you off by over charging for the parts and
you can certainly count the hours for the install.
The controller board is shown here. In my case, this diode fried.
I found a replacement controller on E-Bay for only $82 bucks and change. At the time of this writing they had 14 in stock.

It sounds like you may be having the same problem. But please be sure
to hire a qualified appliance service technician to do the work. If he
quotes a price for the controller board anything over 82 bucks, you
will indeed will be in a better position to negotiate a better deal.
Hope this helps anyone that is having or will have the same problem with an older RV30....

We have the same problem. Our 36RV goes to full on while raising and does not turn off until in the full down position. Has done this from the first month of purchase.
We have the same problems ( the slower speeds quit working). Disassembled the top and cleaned the contacts under the control buttons ( on the circuit board) - it worked for awhile then quit completely. Apparently you cannot clean the area around the control buttons with any liquid since it will get down on top of the circuit board and corrode the surface. Bad design-never worked right from the get-go. I would never buy another Dacor product.
