2003 Sundancer 260 ac/heat

[BennyC1960]

Hello. And thanks in advance for any responses. I can’t figure out how to work the thermostat. Can anyone give simple directions to set the temp for cooling and heat? I tried to put the A/C on yesterday and couldn’t hold the desired temperature.

It couldn't hold the desired temp or you couldn't set the desired temp? Seems like a couple things going on here?

I'm assuming you have a CruiseAir system in a 2003. You should be able to google the user manual pretty easily to find all of the fan/mode functions. Typically you should be able to push "cool" and use +/- to set the temp. That's it...

As Stee mentioned, it's pretty straight forward. If you have the original owner's pack, there was also a manual in there for the AC. But... did you open the seacock and confirm water was pumping through?

Thanks...i have the original manual but I guess it was an option which had separate manual which I don't have. Yes it worked when I had the boat surveyed....I'm probably not doing something correctly. I'm just looking for the basic way to set the temperature. I lowered it to 68 and it kept going back to the temp inside the cabin (88)

Did you push "cool" to make sure it's in cooling mode?

I believe so but will try again today....

If you do indeed have it set to cool make sure it is not "frozen" over or that the filter is not clogged. You will need to pull the vent cover in the mid cabin and inspect. A dirty filter will reduce airflow and can cause a A/C to freeze over which will not produce cold air. Also check for good water flow from the pump by checking for a solid stream on the outlet.
