Reefer Trailer

Had a question. My reefer trailer light was green when I first turned it on, then I changed the set point from 30 to 32 degrees, and now the light that was green turned yellow. A yellow square of lights. Anyone know what this means or how to fix it...should I be worried? The reefer is running though

Yes that means that there is something requiring your attention. On your Reefer control panel, go to the page that shows your error codes or fault codes and see what it says. Don't ignore that yellow light!

Kinda depends on many things.. need more information, like type of reefer , and age.. Our company runs ThermoKings and they have a display that will also show warnings.. The Amber light could be a defrosting, Low coolant, Oil temp, to even ABS problem of trailer.. But the main display will show it if you look at it.. Or it should in the Menu section of it.. The Amber light is mainly for when you are going down the road to let you know in your mirror that there is a problem.. So check the actual display.
