Box temperature is always 3 degrees higher than setpoint

Then why are you guys telling me to clean trash out when I already cleaned the trash out? I don't get it.

 

No you don't have to clean the trash out, but over many years dirt and dust will get up in there and could plug it up. I don't and have never pulled a refer so I have absolutely no idea what you guys are even talking about but I've seen those same plugs in other applications. AC drains or just drains for tool boxes or damp locations vents or whatever. And they can get plugged up.

I was just responding to the question of why would you stick a coat hanger up there. To clean out the goo

 

Gotcha. I check if they have stuff in them by pinching them at the top. This tends to detach any caked-on grit up there, which then falls out when I pinch open the flat part at the bottom.

 

yea i know. but have you ever seen how far up trash can get. you would be amazed how much is up in that hose

 

Ya it can get all the way to the top, which I check from inside the reefer. Although I guess there could still be a unchecked gap between the top of the bottom and the bottom of the top. But my main point was plugs may not be quite so urgent if his hoses close on their own.

 

i just always plugged them on frozen loads. air tight

 

Does it happen to be an used Prime trailer? I picked one up a couple weeks ago and it does the same thing. I send it at 45 continuous and it hangs out at 47. Since I’m hauling sweet potatoes I haven’t messed with it.
My old trailer was always tail heavy. This trailer my first two loads I’ve been in the 76-78k range and still haven’t had to move my tandems. Other then the noisy defrost cycle I really like this trailer.

 

I got mine from Prime in Springfield MO. Had it 2 weeks now. A 2016 Wabash intermodal. They took most of the intermodal stuff off but I had them leave the bumper rails on. What'd you get?

 

It’s a 16 Utility with a carrier. Took a new Great Dane van from IN out to SLC to pick up the trailer. This morning when I woke up the outside temp was colder than my reefer. Wouldn’t you know it my reefer was 43 and I had it set for 45, running continuous. I think it’s some prime setting. Other then a precool I’ve never seen it more than 2 degrees away from the set temperature.

 

Nice, well they do have heaters also, and they'll use either one as needed. Utilitys are real nice, I consider them well built and functional, but for some reason I just can't stand the offset clearance lights, lol. You might see a wider temp range on start/stop but that'd be normal, like +/-5 I think.
