Things haven't changed since 1994 other than types of refrigerants and more efficient equipment. AC units still don't defrost, Heat Pumps still do during the Winter. I'm thinking the problem may be in the t-stat as well as it's location to other possible heat sources that would bring it on. Sunlight and doors being opened and closed. I'm still in the HVAC business since 1976.

I agree totally sometimes people do not realize that the whole in the wall could become a problem letting warm air behind the stat and changing the temp, or all that you posted...........

Well I called Dometic and they told me that the unit changes can speeds and that's what I am hearing. They told me it was normal.

Mine does it too. I was listening to it last week as it was around 98 degrees at 10:30 in the morning...lovely day to pull 800 miles, but I digress.

It sounded to me like it was allowing the compressor to cycle occasionally while changing fan speed. The fan speed may be on a stepped resistor? It has to cycle from one specific speed to another, not linear. It never stopped blowing cold air.

Ours does that when it reaches the set temperature. It will shut down the fan for a second or two then start up again at the lower fan speed. It was unnerving at first till I realized it was doing it every time the fan switched speed. You can check that by moving your set point up and see if it does it.

I noticed our Tracer 15kbtu doing the same thing. I hoped it wasn't an issue but when in extreme heat (beach 90+ degrees) I'll put the fan on high instead of auto and let the compressor cycle.

Re: AC fan stopping issue...

We have experienced this problem with our new 2014 325RES on many occasions at 5 or more campgrounds this summer. We observed that the A/C fan stopped 7 times within a 10-min period with the final stoppage for about 3 sec before the fan speed changed. The problems always occur when the A/C unit needs to change from low to high or high to low fan speeds, but the A/C compressor keeps running even though the fan has stopped. Our dealer has changed the Dometic thermostat and "everything but the compressor and fan" in the A/C unit, but we have not had warm weather to verify whether the probems has been fixed.

Setting the t-stat fan control on HIGH or LOW will prevent the fan from stopping, but then the fan runs even when the A/C compressor is off.

Good luck to all of us that have the Quiet Cool A/C.
