To provide an air conditioner control device which detects a sign of a failure before occurrence of the failure, an air conditioner with the same, a control method for air conditioner and a control program for air conditioner.SOLUTION: The present invention relates to an air conditioner control device 50 provided in an outdoor unit 2 including a compressor 10 and an inverter. The outside unit 2 comprises a detection sensor which detects a predetermined value based on the compressor 10 or the inverter. The number of times that the predetermined value exceeds a predetermined threshold is counted as a sign detection count or the predetermined value is defined as the sign detection count. When the sign detection count becomes equal to or greater than a predetermined count, oil return control for returning oil to the compressor 10 or load suppression control for suppressing a load of the compressor 10 is performed.SELECTED DRAWING: Figure 1 【課題】故障に至る前の故障の兆候を検知する空調機制御装置、これを備える空調機、空調機の制御方法および空調機の制御プログラムを提供することを目的とする。【解決手段】圧縮機１０及びインバータを有する室外機２に備えられた空調機制御装置５０であって、室外機２は、圧縮機１０またはインバータに基づく所定の値を検知する検知センサを有し、所定の値が所定の閾値を超える回数を兆候検知回数としてカウント、または、所定の値を兆候検知回数とし、兆候検知回数が所定の回数以上となると、圧縮機１０へ油を返油する返油制御または圧縮機１０の負荷を抑制する負荷抑制制御を行う。【選択図】図１
