Book says a possible leak in the coolant system but I can't find anything.

Symptom; turn on APU from keypad... system starts... APU starts... Condenser kicks in... APU runs for a minute then dies.

Checked; Oil level, coolant level and supply, belts and all are good.
 
Does your unit have a radiator and a coolant overflow tank and if so does it have a coolant level sensor on it and if so can you jump it?

Fan and radiator but it feeds from the big radiator so I can't look inside the lil bugger. No overflow tank.

Check the freon level with a gauge. You can find the cans of freon with a built in gauge for around $29 or less at an auto parts store. Saves money if you don't have or want to buy a set of gauges.
That's the one thing I have not checked cuz I lack gauges....just ask anyone... I merely hope for an " on the road" quickie that gets my motor runnin'... Then have the TK doc fits it when I get to home base sometime in ..........November?

That's why I suggested buying an all in one kit. $29.oo. I don't know what KIND of freon it is, the new stuff is R134a.......

OK it IS R134a. Here's a manual. Long, but scroll down to pages 93, 94.
1.2 lbs. of R134a

Wonder when R134a will stopped being called the "new stuff"?

If your AC compressor is kicking in and running I would not pump any more gas into it. Too much and you start blowing gaskets. You can buy a bottle of gas with the gauge at any truckstop or Walmart. If it does need gas you have another problem so the fix will be temporary. You can dick around with it and waste your money or you can take it to Thermo King and have it fixed right the first time.

If there's not enough gas, there's a REASON why. It just doesn't fly away.

That's true, but you'll know soon enough if the leak is big or small. A leak can occur from a hole in a line, which could be major, or it could something easily fixed like a schroeder valve.
 
ACS means air conditioning sensor. Either a sensor is bad or you are low on freon. Have it serviced by a pro. It could also be the AC clutch or compressor going bad.

Had the compressor replaced last summer by one of Tulsa's finest....
