Thermo king s 600 HELP no alarm code.

Also your unit will shut off when n it reaches the set point in start and stop, and will go to low idle when it gets within a degree or two when in continuous.

 

Run it +5 -10 continuous, probably what the cold place has theirs set at any way, see if it holds that on low idle. Then bump it to 0

what year is the trailer? 6+ years old with hot product on 90* days will be sure to keep it screaming

 

In the meantime, I would get a piece of wire and try sticking it in the drain hoses and see if you can get some water to drain out.

 

Your welcome

 

There’s a check valve in there not holding the Freon back when the 3 way valve shifts to defrost, just had to replace that on my spread axle

run 0 continuous and so when it shifts to heat it will defrost the system, depending on where you are delivering to crank her to -10 an hour or so before you hit the gate if they check, otherwise I wouldn’t worry about it
