I have a Jayco 247 eagle sl 5th wheel the a/c controls are on the ceiling attached to the unit and the fan runs all the time once you turn the unit on you can hear the compressor kick in & out as the set temp is met. Is there a way to convert this type of unit to a wall mount thermostat or other thermostat control where the fan and unit shuts off once the desired temp is achieved

The conversion would probably run as much as a replacement roof air unit .
How old is your 5er ?

It's a 95

I can't remember seeing the wall thermostat available on any roof air unit that wasn't ducted through ceiling vents.
But if you could post your current air conditioner's make and model , maybe another member has heard of a conversion.
Sorry I should have thought to ask about the brand when I posted the first time.

No problem. It is shot in the dark just would like for it shut off when sleeping, like to hear the night sounds without having to get up and turn off and on

It's not the wall vs internal thermostat that makes the difference - it's the a/c controller circuit board that decides whether to cycle the fan or not. Since the only air a non-ducted a/c gets is what the fan pushes through it, it generally leaves the fan running to help circulate air in the RV and even out the temperatures. Otherwise the internal thermostat only senses the air at ceiling level near the unit.

You can perhaps replace the a/c internal circuit board with a similar one from a ducted unit, but that would depend on the a/c make & model and what functions are on the board. Probably easier to replace the a/c with a ducted model. Sometimes that only requires replacing the inner (underside) half of the a/c unit (it's actually in two parts).

There are a couple ways, I feel they are too expensive though and there is some danger in them.

NOTE: I hear a lot of complaints about the NOISE Roof A/Cs make.. if you run the fan on high your brain tends to filter that one out. You notice the noise a lot more when it comes and goes.
