Found unit compressor locked out on thermal lock out due to start capacitor failing and run capacitor starting to go out of range. Recommend replacing both at same time. System compressor needs to cool, will return tomorrow to complete repair and test system. Pulled unit outdoor disconnect to allow system to cool. Replaced run capacitor, start capacitor, and potential relay. Checked compressor operation by manually pushing contactor in. System will work now with a call for coolung.
