Hi, i am hoping someone can assist me, I have a Carrier Supra 750 truck fridge that keeps shutting down after 5 mins from start up and brings up a "system check" alarm code on the controller monitor. In the back of the truck, the fridge fans are working fine but its just blowing warm air through. I have never had this issue before so i would be greatful for any and all tips on where to start my investigations. Thank you.
