Upon arrival, system was off. Turn3d onto cooling mode so that outdoor unit would come on. Fan motor was very sluggish to come on and compressor did not run, only made a buzzing sound. Found that original 45/5 Dual run capacitor has failed and will need replaced. Parts are covered under warranty but labor is not. Installed new 45/5 dual run capacitor and test ran in cooling mode. No other issues found or suspected at this time.
