Hello, Unfortunately the compressor likely is seized now. There are a couple of reasons that the original start device failed, 1) faulty connection. 2) poor quality part. 3) compressor was running non-stop due to other deficiencies in the unit or 4) the compressor was failing to begin with. The compressor may indeed check out ok as far as electrically ( windings ) but the mechanical component ( rotor ) has locked/seized up. You can determine whether it is the windings by checking the ohm value between common to start, common to run and run to start ( c-s, c-r, r-s ) and look for values similar to 6ohms, 3ohms, & 9ohms. Then check the start and run & common windings against the compressor casing to see if windings are shorted. In order to double check the mechanical component you'd need another hard start, ( or a test cord direct to 120vac, but that should only be done by an experienced tech ). nothing else will start it at this point obviously or you wouldn't be using a hard start already. The other unfortunate issue is this, many of these compressor's have a 10yr. parts only warranty but that was voided as soon as the 3in1 hard start was installed. In the end I'm likely not telling you anything you didn't already suspect or know in fact, but it is likely the compressor. I sympathsize, seized compressors **** ! Hope this answers your question and moves you forward. good luck macmarkus :)
