Check if the 7.5A fuse # 20 (marked as MG clutch - magnetic clutch) in the engine bay fuse block is OK.
Magnetic clutch is the term used for the AC compressor clutch, presumably because it is electrically operated

Fuse 20 does not appear to be blown or corroded

@augustavan81723 since you checked the fuse you know that it at least should have power. I suggest that you next use the self diagnostic function for your HVAC. Here is how to do that.
Automotive AC are pretty complex so it will be difficult to go through each step on here. Use the HVAC part of the SM for your checks and let us know what you find out and where/if you get stuck. Honda Accord HVAC
After the self diagnostics, my next step would be check the clutch itself. if the tests all came back looking good.

You'll also want to check the relay, if the fuse is good. Sometimes the high/low-pressure switch could be bad, causing the compressor not to engage.

@oldturkey03, would you have the Honda Accord HVAC troubleshooting manual for a 2012 Honda Accord SE?
Thank you, Bigfish.

@bigfishtanner I just checked and the latest Accord manual I have is for the 2010

Thank you @oldturkey03! The self-diagnostic procedure showed an open evaporator temperature sensor circuit. I was taking the sensor out and found the last person bent one of the two pins over in the connector.
