    Same problem for me. Runs and blows cold air for an hour or so and freezes up then the unit boggs down with very little air blowing into the RV. Mine is a Duo Therm 15k Quik Cool roof top A/C and is 3 years old. Changed out my T/S earlier becuase it was "short cylcling". That seems to have went away. Cleaned coils but still freezing up.

Why did SPT Portable Air Conditioner stopped blowing cold air?


Unit needs to be taken apart and washed out , also check to see if motor turns freely by hand , clean base of unit fans / blowers and drain ports / channels . Check outdoor motor to see if bearings are tight or fan overheats and cuts off if so replace outdoor motor .

Ckl60-1l outside fan runs good,compressor do not run


Reasons for icing up are dirty filters,dirty indoor evap coil or low on refrigerant. Check these. Your compressor is probably overheated. Let it go for a couple of hours if you are in a hurry. Run a water hose over it. Rus

Fifth wheel A/C PROB


Most probably your unit has no more refrigerant charge. Being unused for 8 yrs will cause leaks on seals.Locate for the system sight glass, run your a/c,if you don't notice any bubbles nor liquid appear on the sight glass your unit runs out of refrigerant.Hope some of this information helps you.

My unit works fine in temperture of high 80s. Anything above that it runs constantly for 5 to 7 hours. I do not remenber it doing this last summer.


Couple or reasons, Unit sized too small, plugged filter or low refrigerant. Have the unit cleaned and inspected by a qualified technician.

I purchased a 1994 5th wheel with a Coleman air conditioner. It had been covered and in storage for 3 years. When I turn on the thermostat, it sounds like its trying to work but quits after a minute or...


You may have a power supply problem. If you are connected to an external power supply with a cord, make sure it is able to carry the necessary power. To small a cord will cause a voltage drop giving insufficient voltage to run the compressor. The noise you hear is the refrigerant pressure equalizing in the system after the compressor shuts down.
