Thermo King TriPac APU Problem

Hello, I've searched this whole forum and can't find a solution for my apu. The problem I'm having is, when I turn my apu on, the blower will run for five seconds, turn off and a red triangle will show along with the word "ENG."

After the blower stops, the apu will crank for two seconds and shut down. I've checked the antifreeze, oil and all of the fuses. Could someone help me out please?

 

If you have a evolution. I will bet my last dollar it's your expansion valve, or evaporator.

 

Yes, it's an Evolution lol. Is there anything I could do until I get to a shop this Friday?

 

Nope.

 

You need to hook up a latop to read the code.
Could be anything from low coolant to high or low presure switch.
And yes you have to be able hook up and read the codes
You need to get it to a shop.

 

Sounds like a heat sensor

 

50/50 odds what I've stated. The new expansion valves are plastic internals. Just to save .02 cents.

 

I just checked my evaporator, and it's full of water at the bottom. What could cause this?

 

Ok. Thank you very much, I'll just idle the truck until I get it fixed.

 

Probably condensation.
