Hey guys. I recently purchased a 2013 Wabash with a carrier 2500 unit . I used the unit for 2 weeks Haven't pulled any frozen loads with it as yet . I decided to test it. I left the unit on overnight at -13. Came back in 12 hours to find the unit off with the alarm on Had these 4 codes . Only issue I ever had is that the box temperature would always be 3 degrees higher than the set point. You will also see pictures of the failed pre trip (this is after I cleared the fault codes ) I had gotten the unit checked at the carrier service center right after I bought. They found no issues
Looks like the evaporator fan isn't turning.Run the unit and check if there is any airflow,if not then probable bad clutch or bad connection at the plug
