Thetford Aria Deluxe II RV Toilet

[Vsilvester]

Hi I am new to the forum I just purchased a 2005 madp and had a problem with the Thetford Aria Deluxe II RV Toilet the dealer replaced the control board when it would not flush it worked fine for 2 weeks then I was in bedroom and my wife was in kitchen and we heard the toilet flush and no one was in bathroom so I checked it and it dead again
I checked the fuse in back and it was fine . We took it back to dealer the next day and when I dropped it off it still did not work
When dealer checked it out he says it was fine and it has been for two weeks
The problem is we just don't trust it and are thinking of replacing it with the aria classic Manuel flush version I can install it myself but it still costs $600 and I don't Riley want to pull the trigger what do you guys think I's the electric version a known problem should I replace ? Are we being to critical Need expert Help
Thanks. By the way I have been lurking for a few months and this forum is a wealth of info I have already learned so much thanks. !

We had an intermittent operation issue with ours and didn't know why. Then I noticed the interior lights slightly flickering. Our RV uses a relay to turn off the 12v supply to the coach. I replaced the relay and the original 2002 toilet issues disappeared. The new relay has the ability to pass the current the toilet needs.

Well just arrived at our short destination campground horseneck beach mass. And the toilet stopped working again checked the fuse and power with test lite tried to open the Manuel valve to dump contents and it just will not budge it turns three or four turns but knife valve stays shut cut power to all circuits to try to reset it and still no good
Had to bail it out and sanitize. So I guess we will have to use the facilities at the campground just called my local dealer and ordered a classic Manuel flush ill install it this weekend and throw this thing away ! And put it behind me ! haha
