Help with A/C on new Passport 175BH
Hello all,
In November I picked up a new 2018 175BH; It's got one Dometic 13,500 BTU ceiling A/C. I know I did a thorough preflight/walkthrough during acceptance, but now with the unit's first use of the summer, I found that the A/C (and fan only) work on LOW and HI setting; the middle setting produces a "hum" but no fan.
I just set up an appointment for servicing for a recall (different story), and let the service center know I had this A/C problem. He quickly said, "There is only a LOW and a HIGH setting, no medium." This doesn't make sense to me, as I can still hear the hum of a motor in the second position.
Can someone clarify this unit's operation?! I am attaching a photo of the sticker.
Along the lines of operation, does the thermostat on the wall have any bearing on the A/C? or is that just for my LP furnace? (There is a hot/cold rheostat knob on the ceiling unit).
I find ALL the operators manuals to be severely lacking!
Thanks for any help.
