Serial number Friedrich AC

[Canadiancold]

Crazy question for everyone but I'm working on a AC so old that I can't find the model number and all I have is the serial number .Need some parts but without the model it's not gonna happen .Friedrich is the type the serial number is JDAJ024194 and I'm 99% sure there is a loose connection or board issue .

Intermittent turns off can go 20 hrs or 10 minutes  ,turns back on or sometimes not and needs the remote to go back on .Outside of that always cold no freezing of the evap,no codes ,drains good , unit is under a solarium no dirt or even minor wear on it .
