Unless you have seen this condition of heat and humidity before, I'd be inclined to think it was/is icing on the evaporator.

air flow over these coils is critical, and maybe the ducts in your unit have a litte bit more resistance. I notice a major air flow change in my A/C unit when I shut off the quick cool dump. Being in Denver, I couldn't freeze a coil if I wanted to

if it isn't a freeze up, then something else, like a relay is going out.

Have spent most of the days in this type of heat/humidity. After getting home, I will open the foam enclosure around the evaporator and get a look see.

Thanks for the replies.

I just bought a new 2013 georgetown xl 378. 2 15000 a/c. It does the same thing since picking it up. My dealer says he has not heard of that before. It might be normal. It doesn't do it very often. We'll see.

Glad you visited there while you were in town. Amazing place.

It is not normal and I am having a problem similar to yours. I question setting the thermostat to 10 deg. below ambient if the outside is at those temps. I am currently traveling and will be home tomorrow. I will keep you posted when I am where I can do a little better troubleshooting.

When you said the fan keeps running during your recent compressor behavior changes, I forgot to ask the obvious, this is with a thermostat set to fan auto not fan on, right?

Edit: nevermind, I see you replied in another thread about AC interuption.

The logic is to ensure the unit cycles on and off to dehumidify the air and cool most efficiently.

Leaving it at too low a temperature setting will cause it to run near constantly and cause ice to form on the coils. This will restrict air flow and further reduce cooling and increase icing. Unless the unit is shut off to allow the ice on the coils to melt, the compressor will eventually overheat and the thermal breaker in the motor will open shutting the unit down.

There were two running threads by the same poster for the same issue.
Both threads are now merged.

Herk-I replied to Bob123 and I used some of the same comments on my post and in a reply to him. That made it look like I had two posts at the same time and then they were combined. This removed Bob123 question.

Bob123, sorry I got your post removed.

I will keep members updated when I get my problem resolved.

That's normal for my A/C and this is mentioned in the owners manual for either the thermostat or the A/C, I don't remember which. My trailer is at a storage lot so I don't have access to the manuals.
