most all appliances are designed to be in an ambient not to exceed 80 degrees. Units will function but not up to design specs and would really strain to work. Only commercial unit can survive in temps up to 95 degrees in the Southeast U.S. and this temp varies depending on your general location.
First question would be, is the compressor running? If yes, then there is a refrigeration issue. If no, then there is either a control issue or compressor component issue. We really need to do the question and answer "game" in order to troubleshoot. Let me know if I can be of any possible help. Good luck!
I can only suggest, at this time, to try and trouble shoot your issue(s) via traditional procedures. In most all cases, a wiring diagram can get you thru most troubles. So sorry I can not be of any further help. I also tried to location info on the internet and struck out at every turn. Let me know if I can be of any possible help. Good Luck!
