Air conditioner (not working) (South Salem)

Portable air conditioner purchased in summer 2020 (retails for around $450). Worked great for two summers but when we tried to assemble it this year, we couldn’t get any cold air. Unfortunately, we don’t have the time (or skill) to troubleshoot it right now. The compressor is under warranty, but the rest of the machine is not, and we would need to mail the whole (huge) thing back to the manufacturer to take advantage of the warranty - with no guarantees that the compressor is the problem. If anyone out there has the time and skill to work on this, it could be a bargain! Would love for someone to get some more use out of it. Very heavy - recommend two people for pickup. Needs to remain upright in vehicle; truck or similar vehicle likely required.
