I have a 2015 Thor Tuscany 40KQ with the AquaHot 400 Heat system, I get plenty of hot water for the sinks & shower, but only one of the 5 heat registers fan is working, I have looked inside and out but can't find any fuses for the fans. can anyone tell me where they are, and are there 5 or just one fuse for the fans
Check to see if you have more than one thermostat, AH normally have "zones" Our coach has a thermostat up front, one in the bath area and a basement thermostat near the water manifold.
Also there should be fuses/breakers labeled for the AH and blowers..
Contact Thor with your coach serial number, model # and date of build , they should be able to provide you with the proper wiring diagram.
The annual service for the AH should be around $300

My 2015 Tuscany had 1 or both of the fans in each register mis-wired. Either the black or red wire was not crimped in the crimp connector. Pretty easy to tug on the wires to see if they are loose? Yes you can spread the crimp connect with pliers and reuse. Think new one are about $0.20 each. Wouldn't be surprised if they were not even installed into the crimp thing. Some of mine were that way!
Forgot to mention that in addition to bad wiring it took a trained Aquahot repairman 6 tries to get our unit anywhere close to working last January in Quartzsite. Seems close to acceptable now. Not a big Aquahot fan.
