Air conditioner cut-off?

[Wijames]

My MH has a single standard air conditioner. Does anyone know of an add on you can get to have it cut off at temp? My compressor cuts off but the fan still stays on. I wouldn't mind except it's right over the sleeping area and is quite noisy.

When your A/C is running, the compressor causes the coils to get cold on one side, possibly causing a build up of frost, and heat on the other side. The fan not only circulates the air but defrosts the cold coils and cools the hot side. The fan needs to run all the time to avoid problems.

You could try turning the fan speed down, but keep in mind that you may then have problems with the coils freezing up, especially in humid weather.

Do the fans on ducted air conditioners run all the time as well? I thought they shut off like a home unit. Also, can standard non-ducted air conditioners be set up to run off of a wall thermostat?

The fan stays on even for the units that are ducted. It does not function like home.

I have a Dometic AC with a wall mounted T-Stat and it shuts off completely when it hits the set-point (just ike our home AC).

Is it a non ducted unit? If so, can you give me the model number. Thanks

My Dometic is non ducted but has the wall thermostat which has auto mode. This mode varies the fan speed by steps and shuts off the fan when compressor shuts off. There's also low-med-high manual modes which the fan continues to run while the compressor cycles.

What brand of air conditioner do you have? I would think something could be whipped up and retrofitted no matter what you have. Perhaps the fan and the compressor could be wired to run/not run at the same time. But I do not know the limitations of the relay/thermostat for this wiring configuration. Maybe someone here does know this....

If our thermostat is in the "auto" mode, both the compressor and the fan will shut off. If in fan mode the compressor will cut off and the fan will continue to run.

I have heard of more complaints from those that shut the fan off than those that continue to run. Once it shuts off it will get real quiet then awaken you from the sudden start up of the fan and compressor.

Ours is ducted so I have both options and usually select the continuous fan on low at night to drown out any outside noises. I prefer to keep some air moving and the ac is a little quieter on a ducted unit.

Actually the ducted A/C fans have auto setting on thermostat then they turn off when temp set point is reached just like home

Non ducted..no wall t-stat fans run until turned off

Not so. The fans in my first MH ACs would continue to run after the condenser would go off, however, the three following RVs the AC would completely shutoff after the condenser stopped running.

Your thermostat is probably in the 'fan-on' mode. Need to switch the mode to automatic so it will go off with the compressor.

Post the thermostat make and model for best answers.
