Question about Heating & Cooling
I have a Kenmore Room Air Conditioner, Model# 580.75121501, 1 1/2
years old. The unit puts out very cold air but the temp controller never
cycles the compressor. I have set the temp control has high as 85
degrees and the room temp is cooled down to 75 and the compressor
continues to run, in both the Cool & Energy Saver modes. In Fan mode
the compressor does not run.

More than likely you is gonna have to replace the control.Sometimes getting a wash rag real hot and going over the buttons will help unstick them.

Doe's the temp reach the set point? If not then it will run until it doe's. If you set the stat warmer and the fan keeps running after compressor shuts off check to make sure it is in power saver mode. Most AC units keep more even temp when fan is left on.

Ours was worse than yours. It was not frozen up, but it did need freon. The tech told us that the compressor coil (the unit in the attic) was leaking freon and that the unit would have to be replaced within a year, but adding freon dropped the temperature inside from the mid-80s to the mid-70s (on 100 degree days). It might go lower, but we don't set the thermostats below 76. We paid $80 for the service call plus another $197 for 3 lbs of freon (for our 4-ton unit). Total cost: $274. The quote to replace the system with a new 14 SEER unit is $7,000 -- but this will get us through the summer. Oh, be sure to replace your filters monthly and keep your condensor fins clean. Spray them down with a hose (even while the unit is running), make sure there are no leaves or other trash blocking them, and make sure you have 2 feet of clearance around the condensor. Putting plants or other objects right up against it will impede its operation. Good luck!

If the a/c fails to continue to blow cold there could be a few problems you can look for. First once you activate the system check to see if the compressor kicks in. You will hear the compressor humming . Once the a/c quits cooling go and see if the compressor is still running. If its not running its probibly gone into thermal overload (compressor overheated). If that is the case then you need to check to see if the coils are icing up if they are icing up then the problem is with 1) air flow restriction filter dirty, coils dirty simple repairs there replace filter, clean evaporator coil with a coil cleaner that can be purchased at a home repair store cleaning the condensor coil the same. 2) system is low on freon in which case the system will need to be recharged. Also, If you have a digital thermostat replace the batteries that may also be of some help. Good Luck on repairs
