The compressor is probably not runnng. 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.

My air conditioner is blowing warm air in the house and cool air outside. The fan outside was stuck and not spinning so I gave it a nudge to get it started now the unit seems to be running in reverse.


You will need to replace the fan motor. Basically when the system starts running in reverse the fan motor is shot, and the electrical is telling to motor to spin one way but since the winnings are shot then are making the motor spin the opposite direction.

AC is set on cool & furnace comes on blowing hat air


My first thought is a bad thermostat or control board or maybe something is wired wrong. If all that seems to be working I would look at the outside unit. if that condenser fan motor is not operating then you wont get any cooling. look for a swollen capacitor. Read more
