sounds like you need to wash your condenser coil. Sounds like your compressor is kicking out on high head pressure. Once it cools off it starts cooling again take it out and give it a bath don't get the electric wet.
I just experienced this problem myself. What helped me was cleaning out the lint trap. My guess is that the until sucks in air through there, then conditions it. Blows the cold air out the top, and hot air out the tube. When it can't suck a decent amount of air in, the condenser can only condense so much of that limited amount of air. When it runs out, the unit just runs the fan until enough air has been condensed.
My lint trap was filthy, hadnt Bern cleaned in years. Soon as I popped it off, the unit started belching out cold air nonstop. Clean your lint traps! Don't make my mistake!
It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.
You are going to have to increase the amount of heat absorbed by the evaporator coil on the indoor section of your system. First change the filter. Second turn the power off to the outdoor section and leave the indoor fan running until all the ice on the evaporator coil has thawed this could take a few hours. Third you need to verify that you are getting adequate airflow across the indoor evaporator coil and the outdoor condenser coil both fans should be spinning at full speed and airflow should be unobstructed by dirty coil fins or debris Hopefully after you've done this you will have cold air blowing inside and the larger of the two lines entering the unit outside will be cool to the touch but not frozen or even frosted regardless of run time and the small one should be the slightly warm but not hot. If the larger line continues to freeze then it could indicate a number of problems but essentially your condensers cooling capacity is outrunning your evaporator coils ability to absorb heat from air stream circulating in your home.Hope it works out for you GL!
