I had problems with the power. When It was restored I tried to turn on the a/c but it turned on then beep and turned off. It the left a red button flashing and beeping. Then on the lcd it says STOP. Please let me know what to do, I reset it and it keeps doing the same. Please help I'm melting!!! Thanks in advance.

The compressor is not taking up and is shutting off. Put the AC off for few hours so that the compressor retains back the oil pumped in during the power break. Thereafter switch it ON-- I am sorry for the heat at your place - If the AC is still showing the same fault I am afraid your will need to check if the starter relay is faulty or not responding or having bad contacts.
when a power disrupption takes place it is normal that the internal timerr will switch off for a determined time to reset the compressor. It will also be good to check your motor capacitor for fault.
If none of these seems to correct, then use a clamp tester to confirm the starting current, if high I am afraid the compressor is faulty.
I hope you start by switching OFF as I pray it works out.
Good day
