How did you know which and how the 3 wires are connected from the control box to the tstat???? Doug

There is a time delay of 2 minutes for compressor operation.
But I think the A/C fan should come on right away.

Did you do the "system initialization" described in the operator manual P3?

It worked prior to putting the thermostat in the furnace worksjust not fno fan or ac once the ac is set I hear the box click like it normally does I will have to check the 110 power

In my original thread linked above member GCLARK recieved a bad contol box from Camping World. If you have 120v power and 12v power coming in to the box and checked the rest of the connections I am not sure what else to say. I assume you read through my install thread and it was very straight forward. All I can think is the box is bad... unless were you having any trouble before?

Does the furnace work?

How cold is it? Might be too low to run the A/C?

I did read an issue that too high of temp (~105F?) will cause the thermostat to not engage... don't know if there is a low temp spec.

Any thermostat error code?

I put in the domestic LCD thermostat.. installed the control box wit came with and now ac and fan won't come on

New box? Is that a new Dometic control box up in the air unit?
Did you get the new Dometic LCD thermostat or are you still trying to make the Coleman work?

Could it be the capacitors? It work before I installed the new box and thermostat

OK so I did't the LCD single zone digital thermostat and new box the furnace work but when onfan or cool the box just clicks like normal but no fan or cool??????
