Hello,

A/C Season here in So. Florida, My system is 5 plus years old and has worked very well. However for the last few trips or weekends on board I noticed that the unit will run fine, and then cooling stops and the vent air is warm. The unit's pump and fans are working fine as is the control panel which shows the cooling indicator lamp on.

Now, I can shut the unit down wait 2 to 3 minutes and turn it on and it cools again.

If I'm not around, see below, it will "reset" itself and cool again.

When away for the boat, a 1997 Island Packet Cat, I leave the thermostat at 85 and I'm sure it runs while we're away; daytime temps in So. Fl are around 90, with water temps around 84, so the unit must run every day, and for a long time. And when we get back the cabin is at 85 so I think it is doing it;s job.

Now I have two questions, one; what can cause the intermittent cooling and is this a pending falult?

and two, do these machines have a "duty cycle" or time they should run before stopping to cool off, no pun intended, or can the run and run with no harm?

Thanks in advance.

Imagine…

Thank you, I'll check the manual.

What would cause the deicing cycle to come to play? Low freon?

Will the icing be visible on the unit?

And I'll go back to the " away " mode for humidity control.

What risks are there in letting the unit run? As in some days it's won't reach its thermostat set point.

All the best,

Imagine…

Thanks again.
