AC compressor not kicking on


I have an in wall Kenmore 240v unit. When I turn it on all functions work but the compressor doesnt kick on. It buzzes for a while every couple minutes and eventually works. What should I look for?

Re: AC compressor not kicking on


Check the run capacitor and wires to the compressor

ohm out the compressor windings (https://www.lennoxpros.com/news/the-...ase-compressor)

If it doesn't start with good windings and a good capacitor, you can try a hard start kit like http://www.supco.com/eclass.htm.

If it doesn't start with a hard start, the compressor is finished and it's wise to replace the unit.
