    Heater fans-gctid825027

    My 3988 has both electric heat and an added Wabasco diesel heater but my issue is I don't have power to the mid berth or salon fans.

    Are they controlled or do they only work when the diesel heat is up and running.

    No information is available on breaker or fuse location

    Picture shows the fan lower right

    Thanks

    Those are King PAW 120 volt wall heaters. The breakers are on the main panel labeled heater. There are three of them.

    The thermostat that controls each one is nearby, in the mid cabin it is on the wall above and to the left of the closet.

    They are an extremely quiet and nice working heater. You may want to have your wiring checked to see if the breaker is bad, the line voltage thermostat is bad

    or if the heater is bad.

    Amazon had a huge sale on them last year and many of us here on the forum bought replacements. I did as well even though my 20 year old heaters still worked.

      In addition, the diesel heater and the electric space heaters are independent from each other. If the diesel heater is of the forced air type, it has a built-in fan on the heater that forces heated air through a system of ducts and registers. If it is a hydronic heater, it circulates hot coolant to a series of air handlers. The air handlers have built-in heat exchangers and fans.

        +2 on the King Pick a Watt. At my home "slip" I'm limited to 15 amps. I was able to select, by which wires are connected, 250 in the guest stateroom and 500 each in the salon and master stateroom on our 3818 and still have enough for a light or two and the refrigerator. And, they fit in the old mounting can with minor modifications and I used the original grills.

          NortonRider is correct on how quiet and efficient these King Electric heaters are. I replaced the salon unit when the drum motor started to make noise and since they are permanently lubricated - there was no use trying to fix. I replaced the heater box can and everything with the black grille (PAW1215). The units can be programmed to 250, 500, 750, 1000, 1250 and 1500 watts. Since the salon is a huge area to warm up - I programmed it for 1500 Watts. In order to use the 12.5 amps (1500W) - I had to swap the salon heater breaker RED 10-amp with a WHITE 20-amp breaker. This heater really warms the salon really fast to the temperature that suits me and I've not had any breaker trip issues even on 30-amp service.

            Often swapping a breaker for a higher amperage breaker requires larger gauge wire to be compatible. 12 gauge with 20 amps and 14 gauge with 10-15 amps?

              Thanks Uncle Bob for mentioning. Yes, I checked the schematics beforehand and the existing wire was 14/3 on each of the (3) heater breakers. Since they are dedicated lines only to each heater I am sure it is in compliance to handle the 12.5 amps.

                I wonder why there was a 10 amp breaker there. Mine are all factory 15 amps which matches the 14/3.

                  Because the original heaters were set at 750 watts and no pic a watt option.

                    A 20 amp breaker should supply voltage to 20 amp wire, not knowing how your larger cruiser is wired, was the existing wire gauge good for the potential 20 amp draw?

                      The wabasco heater has a fan switch the selects low and high but fan does not come on.

                      The previous owner added bridge heating and that fan works and I see a holding tank on the bridge that has no fluid in it.

                      I'm guessing this could be the fluid for my webasco.

                      I will add fluid and see if it produces heat.

                      Thanks

                        You might have to purge any air out of the system if the header tank is dry. Often the fan is controlled by a relay that does not activate until the water temperature heats up. Takes five or six minutes. That doesn't explain why you can hear the bridge fan unless it is a different system, maybe from your engine heat.

                          It may be a different system as the fan is controlled with a 3 position switch and it has a nice tank with a rad cap under the upper bridge.

                          How would I check the fluid level in the wabasco t 70 or does it use the engine coolant. 50/50 anti freeze?

                          The webasco is up in behind the star engine and 8 d batteries.

                          I select the heater on with a toggle switch on the panel and it shows green heater lights off after a minute and then the toggle light goes out but no heat.

                          Thermostats are selected to highest temp.

                          Previous owner is N/A for info.

                            Wabasto is not connected to the engine. If it is hydronic it has it's own header tank. If it is integrated with the command bridge, then the header tank is up top. If not, it might be under a bench in the salon. Of course If it is hot air there is no tank.

                              All good
                              The tank is under the bridge and was low on 50/50
                              Heats well but I think it may have a small leak that I can’t find
                              It was lower on fluid after a few months of use.
                              The fans kick in after the system is warmed up
                              Thanks for the help
