The following have been replaced over the last 2 years and still chattering at start up this year..

System has had the eev valve replaced eev\afc cards replaced as with as the temp sensors. New cap and contactor as well as a good charge and leak check.

Send to run fine for a day or even a few after the tech comes out but inevitably we are right back to the chattering compressor contactor.

Thoughts?
