    Reefer alarm showed up #41 and #42

    #41 Check Engine Coolant Temperature
    #42 Unit Forced to Low Speed

    What do you recommend doing? I have a load on and waiting for another one. Unloading is at night.
    The info next to those codes when I googled tell me to Check as Specified but it doesn't tell me to take an immediate action.
    Is it okay to wait until tomorrow morning? Or should I head to ThermoKing Service right away?

    If and when you are not driving open up the doors of the engine and let it breathe. Just something I used to do in my reefer years during miserably hot weather.

    That’s all I got :)

    That's what I'm already doing. I'm observing the temperatures. It's slowly going down. But I don't know what to do now.

    You check coolant level in the refer unit? I'm sure you did, just putting it out there.

    Check the radiator for being plugged externally with debris. No air flow, no cool. May be a simple as cleaning off some debris.

    Yes, I had to clean it. It's working good.
