thanks, ***** ***** cannot identify it from that information, can you take a photo of it, or give me a model number of the thermostat, does it have 4 buttons or 5 buttons? take a look at this photo thanks
Customer: replied 2 years ago.
unable to take picture tonight, but if I use the thermostat like the one in the picture, I will have to use the power supply that matches that thermostat, won't I ?
Customer: replied 2 years ago.
the one I have is 6 touchpads

thanks, ***** ***** the problem the thermostat and control must be compatable, the ac will plug into any dometic control. so what I need to figure out is if the thermostat you have uses wires to the thermostat or a data cable that looks like a phone cord.........
Customer: replied 2 years ago.
the thermostat that's bad hooks up by a ribbon cable, witch is flat.
Expert:  Michael Reush replied 2 years ago.
thanks thats a problem, can you take down the ceiling panel, and access the control board, and get a part number off of it, you cannot use the new control and thermostat without running new wires, and that is not something you want to do, so lets see if we can match up the control. the issue with the part number of the airconditioner is that the unit is sold in two parts the upper units are interchangable, and will plug into any control,,,,,,,,,,,,,,,dometic created a nightmare, and you are feeling the pain...

I will look at the control board and see if I can deal with it in the daylight Monday, thanks for your help.
