Question about Kenmore Heating & Cooling
This is an intermittent problem. The unit works fine for weeks at a time, but sometimes has the following problem: The compressor will kick on, but not the blower. The blower is not stuck, it will move freely. After a minute or two the compressor sounds labored and kicks off. After a few more minutes, the blower will kick on all by itself, without the compressor. It doesn't matter which fan speed is selected, or whether is is one of the constant fan speeds, or power saver speeds.
Likely a bad motor, when this occurs verify the board is sending voltage to the motor.

I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad.
Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.

Unit#2 -Sounds like the contacts on the master switch are welded closed or the switch is broken, Replacing the switch should fix this unit.
#1 is a little more difficult to diagnose. The compressor is being taken off line by a circuit that protects the compressor from damage either; 1- liquid refrigerant getting back to the compressor which can be caused by something as simple as a clogged return air filter or evaporator coil on a heat pump or 2- overload situation caused by a bad condenser motor or a clogged condenser coil. The first thing you need to do is clean both coils and replace the filter,. Then check to be sure your getting good airflow across both coils. I think it's most likely an airflow issue I hope this resolves the problem GL!

buy a new effecient A/C
I had the same problem but it was my bedroom one so I swapped out my living room A/C into my bedroom and put the new one in the living room.
