AMCORAIRE mini-split M#UCHW-H12AF2 power problems and tech manual

[myrepairman]

I am unfamiliar with this type of air conditioning system: the mini-split. Are there parts available? Is there a technical manual or service diagnostic sheet for this particular unit?

It suffered a burned wire at the terminal connection inside the condensing unit a few weeks back. I repaired it, and it worked for a few weeks, but now there is another problem. The inside display shows 76 degrees, but when pressing buttons on the remote there is no response from the inside or outside units.

As a side note, the problems are likely due to the system being on a shared electrical supply, and in the summer heat, there may be a voltage loss occurring that is inducing problems in this unit.

As usual, thank you for any input, and Christmas is not far away - the beer stacketh up higheth!

... Are there parts available?

.. there may be a voltage loss occurring that is inducing problems in this unit.

1) should be parts available ..

2) wiring diagrams, but nothing in reference to the Remote operation

3) are the batteries in the Remote good ?

4) somewhat low voltage shouldn't cause the problems you're having .. if low enough, would trip the Circuit Breakers (Motor straining)

Yes, batteries in remote are good. Any idea if this manufacturer is common, new, established, junk? I've seen a lot of Korean and some Japanese names out there while crawling around servicing different stuff, but have never before encountered this manufacturer's name. A wiring diagram would be a great help. THank you.
