AC fan

hello everyone, hope you’re enjoying your summer camping trips.
my question today is if anyone can hear the AC fan running. My switch doesn’t say which position is on or off but, no matter the position, I cannot hear anything running. And once I turn the AC on, it is so loud that I couldn’t possibly hear it even if it were running. The manual I have doesn’t even mention the AC fan.

Thank you all,

    Yes, you should be able to hear the AC Fan spinning when the AC itself is off.

    Typical failure cause is a broken wire at the fan motor solder connections. These are small diameter wires with a rigid solder connection that breaks after years & miles of road travel.

    I re-soldered my fan connections twice over three years. Finally replaced fan itself this past spring when the fan blades broke from the hub.

    Function of AC Fan is to draw outside air into the window AC cabinet to improve AC heat exchange operation. Some owners have also completed additional DIY projects to increase the volume of air that fan can pull in.

    @MuttonChops thank you, I had a feeling you would chime in.

    On the photo above, is the fan on?

    Yes.

    Don't forget AC Fan is 12VDC. So make sure other 12V items, like the lights, are working.
