Maybe someone here can help me. I have a 2001 Airstream Land Yacht with two Dometic Duo-Therm Penguin air conditioners. Last month I had the repair shop replace the seal on the front AC. Now it is missing one of the knobs that control the temp. The shop can't find it and I looked hi & lo throughout the unit to no avail. I checked on line and can't even find a part no. for the knob. It is about the size of a nickel, black with a white line on it. Any help would be appreciated because I am trying to sell the MH. You can contact me thru e-mail at: firstname.lastname@example.org
Thanks in advance.
