The other day I was getting ready for initialization and my KREC was under 3. This shouldn't happen I know, what could be the issue? I checked my KREC counter and it seemed to be calibrated properly.

The fan works but it doesn't cool. I don't know the model It's a mitsubishi Mr. Slim wide and long angle.


The compressor probably isn't running. The Main reasons that this will happen
1 - A bad run capacitor (silver or metal capacitor)
It’s either shorted, grounded or open.
If it’s shorted a lot of times it will bulge out, (sometimes slightly)
2 - A bad start kit ( plastic capacitor and Relay connected to it )
The capacitor is either shorted or open
The relay either has an open coil between terminals #1 and #5
Or the relay is stuck.
Any time you change the capacitor or relay you should change
the other, especially if they are over a year old.
3 - A loose, burnt or disconnected wire
4 - Wired wrong
5 Compressor is open (windings burnt open)
6 Low on charge not getting enough cooling back to compressor, (Feel top of compressor to see if it’s hot it shouldn‘t be)
7 Some compressors have a black plastic overload under the compressor cap which could be bad.

The air conditioning wont turn on. The fan turns on but when it tries to cool it just goes back to the fan.

Our air conditioner does not seem to be blowing any cool air...it basically just seems to be acting like a regular fan

The unit is a 12000 BTU energy efficient model purchased from Lowes 3 years ago. It is not cooling. The fan runs fine but it just isn't cooling. The filter doesn't need cleaning. What could it be?...
