OK, all electronic theories are out the window. Yesterday I had the shroud off the A/C and it was very hot in our area. I think it exposed the compressor and coils to more heat than it could handle. Today I put everything back and also cut away some of the grills in front of the exhaust radiator fins and coils. I read that it blocks the airflow and can reduce the cooling effect. I fired the unit up today and it has been running for over an hour. It is a bit cooler today but still plenty hot. 83 today and yesterday 99. I am not sure if there is a safety cutoff on this Coleman A/C but it would not surprise me. Thanks for all your help.
Seriously, get a multimeter, so next time you can determine what is reallyhappening.
You didn't throw any electric theories out the window.
- When it's hot, the compressor load can be a bit higher resulting in more amperage.
- When it's hot, it's common for the electric grid voltage to be lower, resulting in more amps.
But without data, you have no idea if it's simply overloading a 20amp circuit or if there is something unexpected happening.
