My carrier unit won't cool down below 38 degrees. I just had a leak repaired and freon checked and cleaned the coils. What could be the problem?
I'm not a reefer mechanic but I've had that same thing happen before. Our shop had me manually defrost it. I did that an it cycled through an back to normal operation. After that it worked fine. If that don't do it ya may have had a sensor go bad.
