I have a Carrier APAC Sundowner 8kW split. The Model is S008OHR7AN. Its single phase, R22.

It suffered a brown out and has subsequently stopped cooling.

Refrigerant charge is fine and evap fan runs on auto. No compressor run or cond fan run (although pushing compressor contactor finds the comp runs). Reviewing the PCB inside (NR-1) finds it has an error code 59. The table says this is Phase failure and S/R lockout.

So unit is single phase and Ive check voltages to unit now fine.

How do I trouble shoot or reset it??

Please help.
