  • Webasto fan question

    Posted by Dick on April 3, 2016 at 10:43 am

    We have two Webasto thermostats; one in the bedroom and one over the galley counter. We’ve been running the Webasto periodically as we dry camp in the Lambeau Field parking It appears that only the Webasto fan(s) in the bedroom/bath area are running. There is no air blowing out of the vents under the galley counter and in the living room even when the front thermostat is pushed all the way forward.

    Looking at the 120volt panel, I see no breaker marked “Webasto” on the panel which leads me to presume that the Webasto fans are either 12volt or 24 volt. So if the fan(s) up front aren’t working, there must be a problem with a 12/24volt circuit powering that fan … like a blown fuse or a bad motor. Where are the fuses? In one of the electrical bays?

    Is the switch on the bottom of the galley thermostat on. Is the temperature setting higher than the actual temp?

    On our Liberty coaches the entire Webasto system is DC power. The galley system should have multiple fans such as beneath the sofa, behind the dash, under the sink, etc. so if no fans are operating it is unlikely a fan failure. I don’t know if the thermostat engages a relay or if the fans are powered through the PLC relays on the rear wall of the electric compartment via the A-B system. I would start checking those little relays as a start point.

    Jon you’re a genius!!!! It was the switch at the bottom of the thermostat, which is almost impossible to see, which I think Jeff Rowe has told me about and reminded me about more than once!
