I will preface this in saying that I don't know much about electrical stuff (obviously).
So, I inherited this 'older' air conditioner. This past summer, I connected it to an AM466 module so that I could toggle it on & off with a remote.
Now, dismantling it for the winter, I noticed that the electrical prongs have melted the AM466 & there is black staining as well as melting around the electrical prongs.
So this is for my own education- Was the AM466 module unable to handle to A/C? (see specs from the A/C below). Or could this be due to say water (the plug & module lies on the floor under the window & it's possible some rain water/condensation could have splashed on it).
Also, given what you see in the photos below, is the A/C plug done? Should I retire this A/C unit? (I know it's old, but if it's safe to use...it still works perfectly).
Thanks very much for your help.
