Have a 2004 MADP with HydroHot system. The #3 pump on system panel has a red light. Duo-Therm fans are not operational now. Is there a connection? A/C was operational yesterday afternoon (both units); but neither the furnace, heat strips or just fan setting seems to be operational this AM. Also tried running the A/C unit again this AM without success (even though the ambient temp is 57 at the moment!). Have checked fuses, water levels in 12V system and in HydroHot. Cold nights are coming to the South! Suggestions?

Mceaches, welcome to iRV2.

We have quite a few members with the Hydro Hot system, and I'm sure they will soon be along to help.

Hi! I am not sure of the answer for your question. If you can't get the answer here go to: http://autos.groups.yahoo.com/group/...guid=230636861. That group only deals with Aqua Hot & Hydro Hot issues. They are pretty sharp on that site. Paul
