    Cabin heater?-gctid363640

    It got chilly last night on the boat! I turned the knob to "warmer" and turned the fan to "run" and all it didnwas circulate the cabin air. No heat. I have the switch on at the main panel. What gives??

    More info needed!

    Is this cabin heater electric or engine coolant heat provided?

    I'll assume electric.

    If the fan operates, this means that it's receiving a/c power, and it may indicate the electric strip, or a thermo switch that has failed.

    Try turning the a/c power off, pull the cover and expose the element wire connections and the thermo switch connections.

    Take some continuity test readings.

      I bet it's something a lot simpler...like his boat only has AC and not the reverse cycle unit. Just because the thermostat knob says "Warmer" doesn't mean it's going to crank out any heat!

        well..depends on the unit...if you have an airrrr heat/ac unit..it maybe set to ac only..which I believe is #1 on the pad..turn the unit off...then I believe you hold the fan button down until it displays..select up or down to get it to read 1 or 2...or 0 for both...1 I think is ac...2 heat...zero both.....(I'm not at my boat so can't verify with the manual)...

        the other thing is the pump may not be working..in the engine bay there is a water pump that pumps outside water thru the RC unit to produce either cool air or hot air....depending on how it's set...

          It's hard to give helpful suggestions without knowing what kind of heater you are referring to. Can you give us a name/model/picture/etc.?

            My seacock was closed. Opened it, still no heat.

            I dont know what brand/model it is. Its whatever came factory on a 2000/2001 ciera 2855. There are 2 knobs below the V berth. One knob has 3 positions (off, fan, run) and the oter knob is temperature (warmer to the left, colder to the right. What is reverse cycle heat? How does it work?

              RC heating is simply water is pumped thru a heat exchanger fan assy. in one direction..the coolant in the heat exchanger removes heat from the water and provides cool air to the cabin...reverse the water flow and you get heat.....one of those black magic things ......

                You're not getting heat because it's only an AC; warmer in this instance just means less cooler when it's hot out.
