Dometic duo therm fan issue
Ive got a 97 class c with a duo therm ac unit. When I turn just the fan on my generator bogs down and dies almost immediately(fan doesnt start up). Ive replaced the start and run capacitors as well...

It would help if you can provide the brand and model of the new control control board.
Are you trying to use the old Tstat with the new control board?
We need to know which Tstat, brand and model you are tying to use?
A 1997 Dometic if it is a ducted air system, with a remote T stat, it could be a bi metal T stat. Pending that t stat and vintage, there was no 12 VDC power at the control box as the older control box had an on board transformer and created its own control voltage. This could be why you have no 12 VDC at the air box area. The next generation Dometic ducted air system was what they called an analog system control board and the RV manufacture had to bring 12 VDC to the air box area to power up the control system
If you have a non ducted system, that is a mechanical control and no remote TStat.
We need more info on what you have now and trying to hook up to help better.
Hope this helps
